Marucho uses Aquos Bakugan. It is notable, however, that Marucho's Preyas and Elfin can change their Attributes at any time during a battle. His Preyas Angelo and Preyas Diablo are Aquos/Haos and Aquos Pyrus respectively. His Guardian Bakugan are his Preyas and Preyas II
Marucho is a super rich member of the Bakugan- Battle Brawlers. He comes across his Bakugan Preyas on a party held in his huge house. He (with Preyas) and Dan together then fight the big pop stars Jenny and Jewel (who were under Masquerades order) and defeat them.From then onwards their teamwork start and they take full pleasure out of life together.
He is a extremely rich boy who is very generous and intelligent, a bit like a walking encyclopedia or dictionary. He loves to play Bakugan, alongside this is his fondness for creating strategies, over using brute force. He used to be very obedient to his parents just because he wanted to please them, but that changed when he met the Brawlers and Preyas. He now has no regrets for the past, realizing that he only wanted to make his parents happy.He is super-rich but he does not show-off instead he is immensely kind. He and Preyas together, are known to cook good.
Marucho's Bakugan in Bakugan: Battle Brawlers are listed below.
His Guardian Bakugan is his Aquos Preyas, which, later in the series that is revealed to have a special evolution, allowing him to burp up his two, twin brothers. Preyas Angelo with angel looking, and on the flip side, Preyas Diablo with devil looking, which allowed Marucho to not only keep Preyas in his original form, but his 'brother' as well. Preyas was sent to the Doom Dimension in Marucho's battle with Klaus Von Hertzon. Later Klaus shows up with Preyas. Dan and Runo find a way to get Preyas back through defeating him in battle. After this incident, Preyas burps up his brothers, as mentioned above. Preyas also has a effect called "Change of Attribute" with that he can take advantage of the opponent's gate card. Preyas II has a split personality: Angelo Preyas seems to be a bit more intelligent and nice compared to Diablo, who usually says exactly what Angelo says, but in a different way. He reached 7th in the rankings.
