During his battle with Mario and company in the game Super Mario RPG: Legend of the Seven Stars, Yaridovich can create doubles of himself also named Yaridovich. By using Mirage attack!, Yaridovich creates a double of himself. The copy is identical to the original in appearance, but is weaker. After one of the copies received 500 HP of damage, the clone merges with Yaridovich. The two may also merge after a few turns. Yaridovich clones are the only bosses besides Exor that Geno Whirl can do 9999 damage to.
