Well, if that rumor about it evolving into a Fighting/Dark type and Pancham needing a Dark-type Pokemon in the party to evolve is true, then it's likely that its evolution is going to look mean and not so silly.
That's a dumb rumor. And nothing keeps gamefreak from destroying a good thing and making it stupid.
That's a "dumb rumor" that has been correct about a lot of things so far - the names of Pancham, Helioptile, and Fletchling; the existence of the Fairy type and that it's super-effective against Dragon; Sky Battles; the increased transparency of EVs...
Well since it's probably true, it's still an awkward way to evolve a pokemon into a handicapped bear.
How do you know it's handicapped? Also Mantyke would like a word with you.
Mantyke was probably just a filler pokemon gamefreak put in gen 4 because they were running out of ideas. Mantyke shouldn't even be a pokemon. It's like the jaja binks of pokemon, along with spinda, stunfisk, etc.
