Changes

His Partner Bakugan is Aquos Preyas, who crashed [[Marucho's House|Marucho's house]] party, which was thrown after he moved into [[Dan Kuso]]'s town. Preyas was sent to the [[Doom Dimension]] in Marucho's battle with [[Klaus von Hertzon]], which made Marucho want Preyas back so much that when Klaus opened up his portal, Marucho followed him.

Later, when Klaus shows up with Preyas, Dan and [[Runo Misaki]] use the ability Pure Light to win Preyas back. Preyas evolved into a two-sided Bakugan called Angelo and Diablo by coughing them up. Unlike other Bakugan, Preyas multiplies when he evolves, so Marucho got to keep the old Preyas ''and'' the new one.
