Kirby also has many other interesting characters such as Meta Knight, Bandana Waddle Dee, and King Dedede.
Ristar doesn't have any memorable one other than himself.
May be if the game has a sequel it could introduce more characters but sadly there was none.
But what pisses me off is that
he could of! If he had more than one game, new characters could've been introduced and expanded upon.
For example, some of the chharacters from the first game could be expanded upon, such as Planet Flora's elder or Ristars parents.
