Clockwork powered man with a human brain, whats not to love?
Braun is at heart considerate and thoughtful, that is if he has a heart... he tends to overthink most situations and take little actual action.
When braun works he only uses his hands, usually he has a cigar tucked into his mouth.
Braun was an aspiring poet and philosopher when he had a tragic accident at a young age. Still adjusting to his new physique (he couldn't afford a realistic modle so the docs gave him what was laying around) he doesn't really know what to do with it yet.
