Since Joker is finally makign his debut in Ultimate Smash, I'd figure I show off Gurume's persona(Who will take a life on his own). Daddy Grimm.

Daddy Grimm comes from an alternate timeline where being a nature lord, feastbeast, or have any special power outside the norm, is punishable by death. Some how, Daddy Grim goes a step further, as no one is actually sure If he is a nature lord or feastbeast. What is known is that he is suave, sophisticated, and a thief. However, he steals things that are, well, fresh or in the moment. Like a fresh box of doughnuts fresh from the oven, a new car from the lot, he even kidnapped a baby at one time, only to return it safe and sound to their parents. as he states it as his philosophy:" An object that lasts forever is boring. You can view that anytime, but the moment of it's entrance in this world, it is the most valuable and precious of it's kind."

Despite his methods and ways he views life, he does share similarities to his blue mountain counterpart.
Both have a big belly and appetite, both are towering figures, both have a unique reputation, and both actually despise when the rich trample over the poor. Daddy Grim may be a shady figure, but his targets are most often then not corrupted.
