Infinity Trister, Trister (トリスター, Torisutā?) in the Japanese version, is a Gundalian Bakugan and Marucho's Guardian Bakugan in Bakugan: Mechtanium Surge. He is Marucho's fifth Guardian Bakugan after Preyas, Angelo/Diablo Preyas, Minx Elfin, and Akwimos. His BakuNano is Crosstriker and his Mechtogan is Accelerak.
Agile and fluid in his movements, Infinity Trister combines speed with the mystery of his stealth mode to confuse opponents. Extra powers unique to Infinity Trister provide a defense shield which nullifies his opponent's ability in battle.
In Interspace Showdown, he was revealed to be Marucho's Guardian Bakugan in the intro and that he is a Gundalian Bakugan that teamed up with Marucho shortly after the events of Gundalian Invaders. He later helped the children in the arena that Titanium Dragonoid was battling in due to him not controlling his new powers by protecting them when the buildings were collapsing alongside Taylean.
In Mechtogan Mayhem, he battled Krakenoid and he was doing good. However, the battle was interrupted by Zenthon before he could defeat him. He later attempted to battle Zenthon but was defeated in one strike. The battle then had to be drawn.
In Tri-Twister Take Down, he and Taylean were battling against the Tri-Twisters and their Cyclone Percivals, but were losing since it was three against two. They were later saved by Krowll and Horridian.
He appeared again in Back In Sync. He talked about how he arrived in Bakugan Interspace a long time ago, probably during Gundalian Invaders, and was looking for his destined partner. He met many Brawlers but he felt that they were not for him and if it took him years, he would wait. Then, when he saw Marucho battling, he had realized that Marucho was to be his destined partner. He battled again with Marucho against Krakenoid and Jack Punt. Even though Krakenoid used his BakuNano, Jamsaber, Trister defeated him.
In Mind Search, he, along with Marucho had decided to enter the announced "Capture the Flag Tourney" in Interspace in order to limit the amount of chaos as well as finishing the battle as soon as possible. Before that, he and Marucho tried to convince Paige and Rafe not to enter, where they refused. Later on when Boulderon and Wolfurio were badly injured during the brawl with Team Anubias, Trister made interference and transported them to safety. As a result, Rafe and Paige decide to stick with Marucho's strategy, and Trister and Wolfurio were able to distract Sellon, her Bakugan Spyron and her Mechtogan Braxion in order to enable Boulderon to take the flag in which they succeed. In Re-connection, he battled Spyron in the semifinals and won. In the finals, he battled Taylean and lost.
In Dangerous Beauty, Trister is in ball form and is upset that he didn't get the chance to participate in the battle.
In Interspace Armageddon , he joined in the fight against Mag Mel's Chaos Bakugan in Bakugan Interspace before it got deleted.
In Dark Moon, he, Drago, Taylean, Wolfurio, and Boulderon fought to protect Earth and the universe from total destruction, but got defeated by Razenoid while trying to protect Drago.
In The Final Takedown, he was still fighting against all the Razen Titans and beat one using the ability Press Impulse. Later he was happy that Drago survived the explosion of the Dark Moon.
Sometime between The Final Takedown and Evil Arrival, Trister parted ways with Marucho. However, rather than returning to Gundalia, he opted to live on New Vestroia instead.
Because the Brawlers used the Current of Time to go back and destroy Mechtavius Destroyer before he killed him, he is now either living peacefully on New Vestroia or reunited with Marucho at some point.
