Multiversus had a long development period, with a large portion of that time being spent in open beta. And, in the open beta of the game, Jake the Dog from the beloved Adventure Time series was a pretty fearsome character. He was basically Kirby from the Super Smash Bros. games but with more range. Thankfully, while he has been nerfed a bit (primarily in his Where's My Halfpipe Attack) overall he's still the same in the full-release version of Multiversus.
