Dogidogi
Dogidogi shows up in Super Dragon Ball Heroes as basically the evil mirror version of Tokitoki. Mechikabura made and raised this thing specifically to be his dark counterpart, which tracks given how twisted the whole situation is. Later on, Fu gets his hands on Dogidogi and uses it as a key component in manufacturing the Pseudo Universe—so it's not just powerful in its own right, but actually central to one of the arc's biggest plot points.
