Luka

The titular Luka the Great, an inventor and fruit connoisseur! Although an omnivore, he usually eats a vegan diet because his friend Fry does. His status as a thief-catcher is not one he actively sought to earn. His original motivations were selfish, as he only wanted to keep his stuff safe, though later on his personal distaste at invention thieves (and thieves in general) led him to actively pursue criminals he encountered.

He'd be lying if he said it wasn't exhausting though. Can't a dog catch a break?!
