Borderlands 2, Krieg was an intriguing character but as a class generally sucked. His ult was a melee only mode which... doesn't mesh with a game about COLLECTING GUNS. They also introduced Gaige. Her class worked better in the game, although very gimicky, lore wise she was basically a more sane Tiny Tina.
Like... genuinely a series or a movie about him sounds cool... but... I don't think they're gonna show him off like that link. How is an internal monologue supposed to work if only one of the 4 hear it? It can't work while sharing a spotlight.
Also I can't remember if it's official or cannon but
spoiler
Krieg is Tiny Tina's dad so...
so then, do they get along with other spiders as well? maybe we can finally farm some spider silk without the genetic splicing?
