Diesel is my Mewtwo OC. There's a bit of a backstory with him, but the main idea for his character was to take Mewtwo as his personality was from the Movies, put him in the setting that reflected the games more, and inject him with cat-like instincts that he pretends he doesn't have. This works when he's say, reading philosophy in my Pokemon trainer's room, but not when my trainersona buys a new electronic and Diesel's more interested in finding out if he can squeeze himself into the box.

If it fits I sits.
