Since I'm not a fucking retard, I'd go with a Pokemon which can be a pet, is a bro, and has some sort of special utility.
First thing that comes to mind is Tropius, but that only fits one of the categories (utility), and it's an overall ugly Pokemon in the first place. I'd hate seeing that thing daily.
Honestly, I'd go with Gogoat all day every day.
