Mecha-Hitler
Part One: First off, don't believe any of that bullshit people say about how Hitler supposedly "committed suicide". Before His immanent defeat in Germany, he ran away towards Russia where he remained hidden for a few years until his dumbass fell through a patch of thin ice and became a popsicle. A few years later the Russian people found his body perfectly preserved in ice. Using their advanced technology, they removed his brain and locked it deep within a monstrous robot with which the Russsians planned to use in order to wage war upon freedom, Jews, justice, Poland, and general minorities. Mecha-Hitler became to powerful and escaped the Russian military base. He cooperarted with the Japanese after agreeing to give them control of America after he wages war in exchange for upgrading his body.
After the upgrades to his arsenal, Mecha-Hitler betrayed the Japanese and fled to Mexico. Luckily the Japanese were smart enough to implant a control chip into his brain. They deactivated his body and currently is in a state of suspended animation somewhere in the Mexican desert. We can only hope that the Mexican people never locate him and restart his programming.
