Dr O’Neil showed up three days later with a mishmash of metal plates, pipes, wires, a piece of a conveyor belt, a sizeable motor, a car battery, and several other odds an ends. Donatello exulted over the haul. “This is perfect! Where in the world did you find all this great stuff??”
“There’s a scrap yard a bit upstate… I picked up most of it there. It was a long drive, but, well, priorities.” He grinned at his turtle-fied daughter.
“Thanks, Dad,” she said warmly, hugging him.
“All the best for my girl,” he beamed. “And, speaking of priorities,” he said, producing a messenger bag from one of the boxes, “…your homework.”
April let out a less-than-thrilled sigh. “Oh yay,” she said flatly.
Donnie smiled down to her as she pulled her books out to see her assignments. “You may as well get started… I’m just gonna be carting all this stuff down to the next station for the rest of the afternoon, maybe start welding the domes…”
“You’re not building it here, then?” Kirby asked, a bit shocked. “Won’t it be safer here?”
“Eh, not likely. I’ll do the welding here in the garage, but otherwise, it’s better to keep it off-site. It might survive Leo unless Nerfdart Ninja Deathmatch gets out of control, but Raph’d probably put dents in it for laughs and Mikey’d try to use it to make cheeto, onion, and electron pizza,” Don scoffed. “I’ll be saving them from themselves by putting it somewhere they can’t conveniently set off bolts of lightning.”
Kirby chuckled appreciatively. “I can relate. I grew up with two brothers myself.” He patted Donatello on the shoulder and turned to leave. “Good luck. Let me know if there’s anything else you need.”
“Thanks, Mr O’Neil!” Donnie called after him.
April looked up from her pages of assignments. “Are you ever gonna call my dad by his first name?”
“No, not too likely.”
“Why not? He likes you!”
Donnie shrugged as he picked up a box of pipes. “Oh, respect, professionalism… and I want to keep on his good side in case he ever figures out I’m banging his high-school-age daughter while she happens to be compatible with my ginormous penis…” He paused. “Though, putting it that way, if he finds out, he’ll probably make turtle soup out of me himself.”
She blinked, looking stunned and then possibly even aroused, judging by the sultry look she gave him. “Okay, fair enough answer.”

“Mutated?! April got mutated?” Casey exclaimed. “How is that even possible? Isn’t she, like, immune to mutagen?”
Raph shrugged as the two of them walked through the tunnels. “Yeah, well… This was a fluke.”
“I suppose that’s why she keeps turning me down for dates lately...” he mused. “She’s not, like… really hideous or anything, is she?”
“Yeah… that totally wasn’t the shallowest thing you could’ve asked…” Raph snarked at him.
“Oh. Yeah, I guess…” Casey agreed, apologetically putting a hand to the back of his head. “But is she?”
“Eh,” Raph decided after a moment’s consideration, tilting his hand back and forth. “Maybe for a human.”
The two of them entered the lair. Casey glanced around apprehensively. Her red hair wasn’t hard to spot, visible over the top of the bench where she was focused on studying, and was certainly impossible to mistake as anyone other than April despite the green skin, beak and shell. She clamped her pencil in her teeth as she flipped a couple of pages in one of her schoolbooks.
“Red?” he asked tenuously nevertheless.
The pencil dropped out of her beak. “Casey!” She pushed her notebook off her lap and clambered over the back of the bench to meet him.
“…And I guess she’s not totally unfortunate-looking as a turtle,” Raph added to his earlier statement. April crinkled her nose at him, and he chuckled. “Okay, she’s definitely not hard on the eyes.”
“Better,” the female turtle accepted.
Casey gaped, taking in her new appearance. He whipped around and glared at Raph. “You turned her into one of you?!”
Raph held his hands up. “Hey, whoa, whoa! We didn’t do this to her! It just kinda… happened.”
“You sure?” Casey challenged. “It’s awfully convenient that she turned into a turtle.”
“It was more or less a… freak accident,” April explained. “I’m lucky Leo was the last thing to touch me, or who knows what I’d’ve ended up as?”
“Leo? I would’ve figured Donnie—“ He glanced around the lair again. “Where is Donnie?”
April turned a thumb toward the garage. “Welding. Working on something that’ll be able to produce more of the mutagen that did this to me, so he can make a retro-mutagen from it.” Casey paused, now able to hear the crackle of an arc-welder in the background. “He’s really throwing himself into it… he’s been at this for hours!” she continued, casting a warm gaze at the garage. “He’s doing everything in his power to get me back to normal.”
The human teen glared resentfully toward the garage, but turned back to April before she noticed. “Is there anything I can do for you, Red? Anything I can bring you, or…?”
April considered for a moment, but came up empty. “No, not really… Dad is already bringing me all of my assignments and brought everything I need for now…”
“Oh… Well if you think of anything later…” he offered, trailing off.
She smiled back at him. “Thanks, Casey. I appreciate you trying to be helpful. If I think of anything, you’ll be the first one I call.”
He beamed his toothless smile at her.
“Hey, Jones… you want me to show you that new technique or not?” Raph called from the dojo entrance.
“Yeah… There in a sec!” He withdrew from April, ambling to the dojo, turning to dramatically throw a kiss to her before disappearing inside.
She smiled as he left, then shook her head, returning to her homework. She looked up again at the garage and stared at it for a long while.
Construction on the Van de Graaff generator went spectacularly smoothly, if slowly. It seemed like there were always things keeping him from working on it: the usual ninjutsu training, going out on patrol, his and April’s synergy practice, and then there were the times when she just pulled him away to have sex with her… which were admittedly frequent. Nonetheless, the machine was nearing its completion after about two weeks.
He was assembling one of the receptors when April showed up at the platform. She pulled a foil-wrapped packet out of her satchel. “Brought you lunch.”
“Oh, hey, thanks. Be there in a minute,” he called back.
She pulled out a book from her reading assignment, sat on the opposing platform, and started reading… though frequently, he caught her just looking over the top of it at him. He looked back at her. “What?” he smiled down to her.
“Nothing,” she said, and went back to her reading, or rather, staring at him over her book. He caught her at it a moment later.
“Seriously, what?”
“Nothing… just reminds me of something.” After a few more minutes, she took out her phone. “Donnie,” she called, aiming it at him.
“Hm?” he responded, screwdriver held in his teeth.
“Take a step left… now half a step forward—Stop! Perfect! Smile!” She took the shot, looked at it, and grinned to herself.
“Oh, come on, what? Do I have grease on my face or something?” He set his tools down and leapt agilely across the tracks to her. She held out her phone with the picture displayed. It was of him, standing behind the wide, bulbed receptor. The perspective made it look as it if was sprouting from his lower torso, looking very phallic. He bumped her beak and forehead with his own. “You dirty girl!”
“I can’t help it!” she giggled. “Do I need to be punished?” She trailed a hand over his thigh.
He grinned wickedly at her. “Maybe you do. Have you been bad?”
“So bad,” she purred.
“Oh dear,” he said, kissing her neck. “And what have you gone and done that’s so bad?”
She dragged her tongue across the side of his head. “I’ve tried to seduce my boyfriend.”
“Ah. That is a crime,” he smiled while her tongue gave him shivers. “Well, nothing for it, you’re going to have to be spanked.”
“Woe is me!” she dramaticized, throwing a hand to her forehead. “I resign myself to my fate!” She pulled her knees beneath herself and leaned down until her head rested on her folded hands, giving him as much access to her rear as she could, most of it being hidden beneath her carapace. Donnie enjoyed the view of the back of her thighs for a minute, then gave them a gentle smack. April craned her neck around to give him an expectant look. He gave her another feather-light tap in response. She rolled her eyes and huffed, turning back around. She missed the malicious grin he took on. He tweaked her tail, and she squeaked at the unfamiliar sensation. Then he hit her hard enough for the crack of it to echo around the station, and she let out a surprised demure yelp. He repeated the motion and was rewarded with another small noise from her.
He slapped her several more times with varying degrees of force, rewarded each time with a gasp or moan from her. Her seeming enjoyment of the punishment was encouraging to him, in more ways than one. He encouraged himself a little more between the swings he delivered to her reddening thighs, and was soon able to free his manhood from the confines of his shell. He took her by surprise by lifting her back half and forcing her legs apart; she let out a startled squeal. “Or, maybe the rod is a more appropriate punishment for you, hm?” She nearly screamed as he pushed into her. He stopped her by grabbing her ponytail and yanking her head abruptly backward, cutting her off. “Sh!” he warned sharply, then started giggling. “I don’t want the guys to hear us!”
April turned enough to give him an odd look that read as “Really??”, but she complied, confining her pleasured outbursts to near silence. Tiny gasps and heavy breaths that would have been moans from her told him what he was doing right. Donnie found it a difficult task himself, having to breathe heavily or cut off a groan as her body clenched around his hardness. He caressed her sides, then gripped her shell where it curved inward at her waist and shoved himself as deeply as he could into her, eliciting a silent scream from her, her neck arching backward. Seeing the pleasure he brought her was enough to push him over the brink, and he spilled into her with a choked, soundless groan. She was left gasping as he retracted from her.
“There, now,” he panted. “I hope you’ve learned your lesson.”
“I don’t know… I may need a reminder tomorrow,” she teased, not moving from her position on the floor of the platform.
“Woman, you are insatiable!” he jabbed back. He fiddled with the foil packet April had brought him, pulling out three slices of pizza. “Looks like the Michelangelo special of the day is gummi bears, chocolate chip and calimari…”
“No one ever explained the limitations of what should go on pizza to Mikey, did they?”
“Don’t be ridiculous… “ he replied with his mouth full. “You can put anything on pizza.”
April sighed. “That’s kind of my point…” She picked up her phone and checked the time. “I guess we’d better get back… almost time for training.”
Leo came out of his meditation. He didn’t like what he’d thought about, but it was clear he needed to confront Donatello with it. He stood and exited his room. He peered into Don’s lab, peeked into the kitchen in case anyone was there, checked the dojo space. Raph and Mikey occupied the floor in front of the TV, playing a fighting game.
“Anybody seen Donnie?”
Mikey answered innocently, “He’s probably off showing April his staff.” Then he cracked an impish grin.
Leo stared at him, then glared at Raph. “You told him to say that,” he said, at the same time Raphael said, “I did not tell him to say that.”
The lair was uncommonly calm as they entered. Raphael was pummeling the punching bag in the training area. Michelangelo lay on the floor, engrossed in a comic book. Leonardo seemed to be meditating by the steps of the entrance, but stood as Don and April arrived. “Hey, Leo,” Donnie greeted, knowing by Leo’s look that he had something to say.
“Hi, guys, glad you’re back. Donnie, can I talk to you for a moment?”
Hoo boy… he thought. If Leo wanted to talk about something, it was bound to be bad news. “Sure, Leo,” he nodded. “April, d’you…” he started, but she was already walking off with a backwards wave toward them. He smirked, watching her go.
Leo motioned to him as he passed the turnstiles. “C’mon…”
April headed down to the benches and opened her book, squeezing in a little actual homework before training began. Mikey looked up from his comics to give her a sedate grin. “Hey, April.”
“Hey, Mikey,” she grinned back.
He tilted his head toward the gates Donnie and Leo had just left through. “Donnie’s my best bro,” he said kindly. “It’s good seeing him happy. I’m glad you guys can finally be together.”
April smiled broadly. “Thanks, Mikey.”
“Okay, what is it?” Donnie pressed, once they were clear of the lair’s entrance.
Leo sighed. Whatever it was, he really didn’t want to say it, but knew he had to. “Have you noticed April acting a little… weird?”
“Weird how?”
“Like…” He shrugged and sighed. “…aggressive. Sexually.”
Donnie’s eyes went wide. “WHAT?!” He stabbed a finger at Leo’s chest. “Are you just being jealous of us? Finally, fate deals us a good hand and we’re able to be together, and you can’t stand letting us have that? Or that there’s not enough turtle-girls to go around, so no one’s allowed to have her, is that it?”
“No. Listen. We’ve been treating April’s mutation like it was completely stable—“
“—Which it is!”
“We don’t know that for sure! The electrified mutagen was made from the same basic mutagen the Kraang have always used, and we know that’s unstable. And just about every mutation we’ve seen has gone crazy aggressive on us… Think about it… Spider-Bytez, Leatherhead, Dr Rockwell, the Rat King, Timothy…”
Donnie looked away. “…Timothy.” Leo had struck to the heart with that one. Despite the fact that the idiot only had himself to blame for everything he had done to himself, Donnie still felt the guilt of failed responsibility for the kid.
“Even Sir Malachi wanted to keep us in his game forever…” Leo pointed out. “And most of them were aggressive from the start… Rahzar, Fish Face, Bugster Dorkman… It took Snakeweed a couple weeks to completely lose his humanity and start trying to be a cannibal…”
Donnie mulled this over. “What about us, though? What about Master Splinter?”
Leo gave him a flat look. “We’re ninjas. We hit stuff every day, and we discipline ourselves to keep our aggression under control… er, except Raph. Master Splinter was already a ninjutsu master when he was transformed, and he trained us basically since the day we mutated. But April… She’s got a fraction of the experience we have. I don’t think she has the restraint she would if she was… normal.”
“But she’s not aggressive! She’s still sweet, wonderful April.”
“Look, I’m not the science nerd you are, but I have seen some nature shows, and there’s some fairly universal gender roles at play: the males fight for territory or mates, and the females produce and raise the young.”
Donatello looked floored. “No. NO. I am absolutely not believing you!”
“Donnie… She’s been here two weeks. How many times have you had sex with her?”
“That… is…” He wracked his brain. “…none of your business!” he decided stubbornly.
“Come on, Donnie…” Leo pressed. “How about the past week… is it more or less than you can count on both hands? How about since Monday?”
Donnie pointed at him again furiously. “You are really crossing the line here, Leo!”
“How many?!”
“Five!” he shouted back. “Okay?!”
Leo was taken aback at the response. He did some mental processing, then checked, “In three days?” He sounded rather impressed.
“Why are you so jealous of us? Oh, wait, I know, it’s because you and —“
“Don’t you bring her into this! She has no part in this discussion.”
“Oh, really? Because I thought that as long as we were talking about aggressive mutant girlfriends—“
“It is not the same situation with us and you know it!”
“Then why are you trying to cockblock me?!”
Leo breathed in calmly. “I’m not out to cockblock you. I just don’t want you to be the last to know.”
Something clicked in Donnie’s head. Leo’s point had made it through. He calmed, even looked a bit guilty. “Fine,” he said at length.
“Are you gonna believe me now?”
Don didn’t look at him. “I’ll… take it under consideration.” Pensively, he headed back into the lair.
Three days later, Donnie trotted down the steps and over to where April was doing her homework on one of the benches in front of the TV. He nibbled her neck playfully. “Donnie!” she shrieked and swatted at him.
“It’s done!” he announced gleefully.
“It’s done?” she asked to verify, as though she couldn’t believe the good news. A joyous smile spread over her face, and she threw her arms around his neck. “Oh, Donnie!”
He picked her up, swinging her over the back of the bench. “You wanna come test it out with me?”
“Hell yes, I do!” she bounced.
“C’mon…” He pulled her by the hand to his lab area and took a flask of mutagen out of the mini fridge there. He opened it carefully and transferred the contents to another similar container, but this one had a metal bar set into the middle. “This is to conduct the electricity directly through the cylinder,” Don explained. “I want it to go directly into the mutagen, not just bounce from one cap to the other.” He sealed the container and grasped her hand again. “Let’s go!” The two of them bounded out, running down the corridor.
Donatello guided April up onto the platform and onto a rubber mat. He flipped a switch and the motor whirred to life. “Stay here on the mat so you’re grounded. I’ll have you turn the voltage up if we need to give it more juice.”
“Right,” she nodded.
Donnie took his place on another grounded mat and affixed the mutagen to the end of a long pole with a metal end. This was wired to the machine, which was beginning to produce small pops of static. He pulled his goggles down over his eyes. “Ready?” he asked. April nodded. Donnie held the mutagen-tipped wand toward the metal dome. There was a loud CRACK as the static charge jumped from the dome to the canister. He retracted the wand and examined the mutagen. No change. He tsked.
“Turn it up to 20,000 volts,” he called to April. She twisted the dial and the generator’s motor whirred faster. Once more, he held the wand out, and the electrons jumped to it with a loud snap. He pulled the mutagen back again and looked at it. Nothing.
“30,000!” he hollered over the motor. April adjusted the dial again and gave him a thumbs up. He waited for the little static crackles to ramp up, and extended the wand again. Zap. Nothing. He shook his head, dismayed and becoming impatient.
“Go ahead and give her all she’s got,” he called. April twisted the dial all the way to the 50,000 volt marker. Donnie held the rod out, and the small lightning bolt struck the container. Surely now… Please…
The mutagen stubbornly remained its usual glowing bluish green. He groaned in disappointment. “Dammit…”
April shut the machine off and walked solemnly to his side as he sat down on the platform’s edge. He pulled off his goggles and tossed them over his head at the disappointingly insufficient Van de Graaff. “So… what happens now? Can we build a bigger one?” she asked.
Donatello shook his head. I don’t think we’ll be able to find a motor much better than the one we’ve got, and even if we did, maybe we could push it up to seventy or a hundred thousand volts… but a bolt of lightning can be upward of five million. I was hoping a small charge would be enough, but…” He gave an exasperated sigh.
She pulled him toward her, stroking his head. “It’s all right,” she said sadly. “I’m sorry it didn’t work… We’ll find another way.” She gazed softly into his eyes, and they felt their synergy kicking in. To be honest, I don’t mind waiting, she thought, as long as I have you.
The two of them were still deep in their synchronized state as they came back to the lair. Their surprise, synergy aside, was the same at hearing a familiar voice. “Casey Jones shoots the ramp! He scores! High score defeated, Raph!”
Raphael swung his shell into the machine and game locked up as the TILT lights flashed. “Oops,” he grinned as Casey’s ball went down the drain.
“Hey! You are such a poor sport…”
“Casey!” they said as one, not even aware of doing it, though April’s voice was enthusiastic, and Donnie’s slightly bitter. “What’re you doing here?”
Donnie felt his emotions of distaste for his rival clash with those of April’s attraction for him. He could also feel her shooting him a mental dirty look for thinking badly of him. He wished that they hadn’t been connected at the moment.
Casey whirled and backed into the pinball machine, flinching at the weird duality of their speech. “What the hell!?”
Raph rolled his eyes. “Aw, great… they’re doing their creep-o ‘Shining’ routine again… Seriously, would you guys knock it off with the stereo shit?!”
“Oh, sorry… give us just a second…”
They went through the steps of disconnecting themselves quicker than they intended. Donnie felt like he and April had torn apart, shredding part of his brain. He grabbed his head at the sudden pain and vertigo. “Ow… damn, bad idea…” April appeared to be going through similarly rough withdrawals, sitting down on the steps and rubbing her temples.
“Are you guys okay?” Leo rose to steady his brother. Mikey, splayed out on the floor in front of the TV, kept his place but looked up in concern.
April grimaced at him. “Been better…shouldn’t’ve rushed coming out…”
“What was that, some weird ninja-Jedi mind-control trick?” Casey queried, seating himself beside April, rubbing her shoulders in an effort to alleviate some of her pain.
“It’s this ‘synergy’ thing they’ve figured out how to do, where they share thoughts or something,” Leo explained.
Casey shot a sidelong glare at Donnie. Don gave him a smug grin in return. “Yeah… I really know how to get into a girl’s head,” he said with a lopsided smile, then went back to trying to suppress the lances of agony shooting through his skull. “Really botched it on the dismount, though…”
“How’d the test go?” Leo asked, trying to give Donnie something else to focus on.
Donnie winced, looking at him out of one eye, a hand over the other, and shook his head very slightly. “Nothing short of a lightning bolt is going to alter the mutagen, I’m afraid…”
Casey’s eyes widened. “Does that mean you’re not going to be able to fix April?”
“No,” Donnie declared with certainty, and a breath of relief as the shooting pain began to clear. “It does mean that she may have a very long time to wait until I can find a way to duplicate the ionized mutagen..”
Mikey interrupted from his place on the floor in front of the TV. “Guys, look! TCRI’s on the news!” Sure enough, the TV showed a still of the TCRI tower being struck by lightning.
“Turn it up!” Donnie demanded.
“…was captured by one of our viewers during the last major storm. The TCRI radio tower has been struck a record 821 times since its construction in 2003, almost as if Mother Nature herself has a beef against the building. But as for us lowly humans, we’re glad to have TCRI taking all the hits for us and grounding all those lightning strikes. There’s another big thunderstorm heading in this weekend, so here’s your chance to potentially take a great shot like this one, weather-watchers and photo buffs! Temperatures will be in the high 80s through Thursday at least and humidity will be high, with a high chance of major storms throughout the week… Better remember to roll up those windows and bring your umbrella!...”
Donnie’s eyes moved across the image on the screen. “I’m getting a really bad idea…” he said, stopping to think it all the way through. “Yep, this is definitely a really, really bad idea.”
