Super Smash Bros. Lore!
This is not official, it's some weird stuff made up by me and my friends
Mr. Game & Watch
Mr. Game & Watch formed out of the souls that perished during the Eternal War in the Subspace. Because he is a weird abomination, both Kirby and Jigglypuff want him dead, and he went into hiding. He later joined the Defenders, and can use his souls to fuel his dark magic. The souls in Mr. Game & Watch have been dead for too long to return to the world of the living through the Defenders' portal. Mr. Game & Watch can Judge the souls of people who are still living, sending them to the Nine Hells (the number he gets is the Hell they go to).
