Nazi Grandpa

Nazi Grandpa is the debut episode of Felix Fitzgerald and the Genetic Soda.
==Plot==
"Felix Fitzgerald, I can't believe that you've ended up here again," the man's voice heartily boomed throughout his office, a mix of disappointment and mild annoyance mixing in the hot late summer air and colliding with Felix's eardrum. While other boys may have cracked under this tone, the two boys currently inhabiting Principal Foozle's office seemed as if they were perfectly content with just staying there and doing nothing. The two of them showed no signs of emotion, watching each other carefully out of the corner of their eyes. Neither of them would be the first to break, and so they continued in their feirce staring contest.
But they did not continue uninterrupted for long.
"Didn't you tell me you were off to a new start, Felix? Earlier in the morning, wasn't it?"
Nothing irked the boy more than being reminded he was not the man he thought he was, and so Felix's frustration finally came to fruition. He stooped forward in his slightly uncomfortable chair and slammed down on the principal's mahogany desk. 
"I was!" He protested, unaware of the fool he was making himself out to be. He slammed his fist on the desk again, enough to jumpstart the principal's Newton cradle with a fuel of pure dissent. "I still am!"
"Then why are you here?"
"Because he called me an asshole!"
The principal turned his head to the other boy, and raised an eyebrow. He hoped this one would finally shy away from stoicism long enough for him to answer a question. 
The lips to the boy's mouth slowly curled and lifted, emanating a flat, monotone voice.
"It was meant as a term of endearment," the boy explained.

"I don't care what either of you say, or what either of you want to do. You're going to do what I want and you're going to go where I want to go," the girl said, her manners uptight as she looked down at them. Her face was held high, tilted slightly towards the sky so it seemed as if she was constantly looking down at them despite her vertical disadvantage.
"So she's not stuck with us... But we're stuck with her?" Felix reasoned, attempting to conversate with his fellow victim. Instead, the boy merely shrugged it off. (girl) smiled, partially delighted by her captive's stoicism.
"FELIX FITZGERALD!"
The man hobbled up to Felix. Felix, stunned, could not get out of his way in time before he gripped onto the undersides of Felix's forearms and fondly regarded Felix's face. Instinctually, Felix scrunched up his nose. The man smelled terrible, like rotten eggs, and smoke, and... a cool ocean breeze.
"My boy, you've grown since I've last seen you!" 
"I don't... Know... You?"
He cast his arms aside from Felix's shoulders. Felix, still stunned, let his arms be thrown to the side.
The strange traveler pulled out a silver pocketwatch from the inside of his overcoat. He held it up to the light, as his eyes fluttered from the face of Felix to the face of the clock. Felix did not understand what the point of this was, for the time did not seem all that important, yet to the man, it seemed to be the most important thing in this world.
Following this, the aging man held his arms out for Felix to hug, though Felix did not follow through. The man merely shook this rejection off with a smile. "Boys will be boys, I suppose!"
He headed for the front door of the Fitzgerald household and welcomed himself inside. Felix looked at his sister, who merely smiled, shrugged, and followed him indoors to merely witness what this strange man would do.
Felix sighed and eventually followed her in.
The man raided the pantry first, all the while muttering something about how starved interdimensional navigation made a fellow. Felix didn't question the notion, though he did rank him a few slots lower on the sanity scale.
(he tries to make a really weird sandwich, and that sets Felix off)
However, before he could dip the unholy combination into the coffee and finally bring his monster to life, Felix grabbed the sandwich with one hand and the mug with the other, and promptly wrenched them away from the odd man's hands. The man simply stopped and stared at this mannerless barbarian.
While the man's jaw was dropped, Felix seized the opportunity to properly use his. "Who the hell are you and what the hell are you doing?"
"You see, Felix...
BACKSTORY:

*Iron Phoenix used a time warp discovered by Oskar
*In another timeline/dimension, Iron Phoenix perfected the Genetic Soda
*Oskar had a change of heart and massacred the other scientists before they could return to Berlin
*Survivors of Iron Phoenix were kicked out of the timeloop here, and Oskar followed
* 
*Felix's family are descendants from an alternate timeline
*an Evil Empire descended across the timeline, and Oskar was complicit in their rise as a member of the elite strike force, Iron Phoenix. Evil Empire absolutely desolated the Earth and left its resources raw
*Oskar went with Iron Phoenix to find a new Earth, but while they were crossing the Void, he backstabbed them
*in the new earth, Oskar found a wife and had a family. when he told the truth to his wife, she slapped me and told him he had to do something
*Oskar faked his death as a drunk (so everyone would be motivated to forget him) and went back in the Void. 
*Oskar explores the void
*Oskar returns, but finds that the Cult of Iron Phoenix has already returned
"Your grandmother was no tame dame, however! If I was a firecracker, she was a stick of dynamite! When I told her of my secret origin, she had one bombastic response!"
"What was it, grandpa?"
"She slapped me upside the head!"
"Women-on-male abuse isn't something to glorify," Felix grumbled.
"Ah, but boy! Sometimes we can all use a good wake-up slap! It can stop us from going down the wrong path, or from abandoning the right one!
"Your great-grandmother's vivacious approach to life reminded me of why I had left the Iron Phoenix in the first place! I could not just abandon my fellow countrymen to a dimension of endless enslavement! I had to right my wrongs.
"Over the next couple weeks, I spent tireless nights building not only a machine that could return me to the void between dimensions, but a reputation as a drunk, too! When my time came... I created a brainless clone, and let his body be discovered in a ditch! I left your world, with all of our family viewing me as an utter disgrace.
"I returned to the void, and spent the next few generations of my life finalizing the weapon we had been commissioned to create. I had plans on using it on them, to vanquish the Cult in the void and return home, but before I could challenge them... I learned that they had already arrived in your time. Here! The time of my very own great-grandchildren! I had no choice but to follow them..."
"So, you want our help
"No! Absolutely not! The revolution must happen from within! We cannot colonize their world with color, just as they try to enslave your timeline with evil! I am here to save your time! Only with your cooperation can we defeat the Cult of Iron Phoenix and turn them back in time!"
"Well, why don't you fight them yourself?"
"The technology won't work on me.
"So why me?"
"Because you possess the genes most similar to mine. I designed the device with a lock on my own DNA."
Felix popped the capsule into slot on the wristmount gauntlet. Then, with deft speed, he snapped a switch shut. The transformation process had begun.
"Felix! He's just a distraction!"
