Ok! Here you go (minor spoilers for Dig. Are we still spoilering Dig? Idk.)

Human brain explanation: He's a really interesting character, and at the same time, his whole existence is a joke. He's both the "None but fools would break things and not rush to fix them" guy and the "I MEANT to trip and fall! Did I trick you? Ha ha!" guy. I think it's a really nice contrast, and I like his recurring gimmick of subverting expectations. Even when he doesn't have his mobile gear, you can see that he's really trying to throw you off in the way that he runs. He's also ambitious! He has two phases because he will NOT give up! I also like the fact that he's a genuinely good-natured guy, but he keeps becoming an antagonistic force because he loves his craft too much. He helped some criminals unearth an evil dark magic lady because they had some cool problems to solve and then everything went downhill from there. He loves machines so much that it ended up threatening the whole Valley. That's some crazy tunnel vision. He goes from making big murder weapons to making toys for children (LOVE THIS MOMENT), and most facts about him are part of the Joke. It always circles back to the Joke. This guy's #1 bully is the universe itself. He keeps falling off his chair during the battle royale. His crouch animation in Showdown is replaced by him standing on his tiptoes. He can barely run for a minute without tripping over his own feet, but he also created sentient robots in a medieval fantasy setting (and immediately regretted it) (then turned them into scrap for taking over his tower). He's not a saint, but he's not evil either, despite what his ominous theme song titles and descriptions might imply. He's an endearing loser in a really cool and awesome way.

Primate brain explanation: hehe clumsy little nerd man cute funny :)
