Dexter had done an experiment, and it had gone horribly wrong. The problem was that he didn't remember it. Only Samurai Jack did. So, every so often, the martial arts master came by to try and remind him of it.
It went something like this.
Dexter was working on plants and aging again, but this time he made sure Dee Dee wasn't in the lab. He fired the laser. Samurai Jack just happened to swing his sword under the beam, and the laser bounced off and hit Dexter. Samurai Jack caught him before he fell, but Dexter had changed. He was making plants older, Jack realized in horror, as a young man around the age of about twenty-one years old lay unconscious in his arms. His curly hair was straighter and fell in his eyes, his glasses were smaller on his face, and his pale skin was flawless with the exception of a scar across the bridge of his nose. His clothes had even gotten bigger with the body -how, Jack didn't know, but he didn't doubt anything about Dexter...even his clothes. The handsome young man mumbled in his sleep and sat up groggily, rubbing his eyes under his specs.
"What in the world just happened?" he asked, voice low. Even his voice had changed! Jack thought in dismay. "And why do I sound different? Samurai Jack-san?" He turned to face Jack with sparkling blue eyes.
"You got hit by the laser," Jack told him awkwardly.
Dexter's eyes widened behind the glasses. "Oh...well..." Dexter stood shakily but quickly regained his balance. His legs were long and slim, and he had a bigger build. He was inches taller than Dee Dee. Jack's eyes widened. This was the man Dexter would grow up to be. Strong, confident, calm, and good-looking. Jack smiled.
"Who would be able to fix you?"
Dexter smirked. "Just because I'm older, it doesn't mean I'm less intellectual. I can program the laser. You just have to hit the button when I'm in position."
"DEXTER! Lunch time!"
Bubbles' voice echoed off the lab walls.
"Oh dear," Dexter breathed.
"I brought you some...soup..." her voice trailed off as her eyes caught sight of him. "D-Dexter?!"
"Yes?" he squeaked nervously.
"You-You-You're...wow," she gushed, eyes hearts and drooling. He looked at her innocently. "I have to show Blossom and Buttercup!"
Dexter shivered. "I can just imagine what Buttercup will say," he shuddered. Jack smirked. Poor kid, he thought. Dexter blinked with long eyelashes and covered his eyes. "Dear Einstein, I need to change back before-"
"WHOA!" Blossom and Buttercup shouted. They hovered in front of him, jaws dropped. "Dexter, you're...!"
"You're hot!" Buttercup finished for her sister. Blossom blushed and pushed her sister playfully. "Seriously, how did the little science boy turn into...THAT!"
As the girls drooled over him and Dexter stared at him with wide, pleading eyes, as if saying "help me", Jack sighed and shook his head.
"He even has the accent!" Bubbles squealed. The girls laughed in agreement and hugged him. Dexter grimaced and stared at Jack, desperate for help.
"Girls, let go," Jack finally interrupted. "He needs to get back to normal."
"Ehh, but why?" Bubbles countered.
Dexter sighed. "I really need to change back soon," he whispered under his breath. "I can't handle girls. Armies of mutants, yes. Girls...no. Never."
Either Dexter had blocked that memory out, or his brain had lost it in the transformation process, but Dexter didn't remember a thing.
The girls did, though, and paid extra attention to him from that day forward...to which Dexter was oblivious of.
