I actually have his origin story. Goes a lil' somethin' like this:
Regular armful human man: Golly, working in a german factory with almost no safety regulations and no health benefits whatsoever sure is fun!
Gets arms torn off after they're cuaght in a machine.
Regular armful human man: .....well don't that just beat all?
Later that night...
Regular armless human man: Even though I am dissabled, I shall hone my body so I can function better than I ever did with my arms!
A few months later.
Armless Tiger Man: Besides the unforseen and highly improbably side effect of my face taking on cat like features and my teeth growing into fangs from using my mouth to hold things so much, I'm in the best shape of my life. Now, to declare a war on all machines.
Skynet: ....****.
Nazis: Hey, Armless Tiger Man.
Armless Tiger man: 'Sup?
Nazis: We really don't aprechiate you destroying our industrial factories like that. It's kind of an act of treason. We're going to have to, you know, kill you.
Armless Tiger Man: But I love Germany. I am a proud Nazi. In fact, when I was twelve, I would put chairs in the way of the Jewish kids in my school and put a penny by my feet just to watch them trip over for it. I just hate machines.
Nazis: Okay. Compromise: Wanna destroy machines in America?
Armless Tiger Man: Does a fat kid love cake?
Nazis: Not anymore. We killed all the fat children.
Armless Tiger Man: Oh.
Nazis: Yeah.
Long pause.
Armless Tiger Man: Okay, I'll do it.
