Disgaea characters you feel could have been represented in SSBU

Yes I know the DLC support for the game has ended such a long time ago as lately I couldn’t help but wonder who could have made it to the roster of the game.

I know that SSBU had RPG characters from games like Final Fantasy 7 and Dragon Quest as lately I was trying to come up with some ideas on what Disgaea characters again could have made it into the roster since some I could see being included were Laharl and Adell due to their prominent nature in the franchise since they always show up in the mainline Disgaea games.
