Here's some I think you can add to the list.

Sonic the Hedgehog: I'd like to see more Sonic villains like Chaos and maybe Rouge the Bat.

Super Mario: Bowser Jr is the most overdue nintendo character imo. He really needs to appear soon.

Tekken: Most overdue franchise for death battle imo.

Pokemon: Arceus really needs a death battle.
