Oh yeah? Well on Gundalia, we have a saying: The dude who yaks and yaks should get to the point instead of talking in circles.
Infinity Trister, Interspace Showdown

Infinity Trister, known as Tristar (トリスター, Torisutā?) in the anime, 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.


Bakugan: Mechtanium Surge

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 is shown arguing with Taylean and Dan saying he should battle while Dan sits out. Before Marucho and Jack Punt began to battle he gets cocky saying they will win easily. he later battled Krakenoid in a jungle like environment. Krakenoid starts off by using fish flop turning invisible and submerging him in water. He then uses Aquos Mine and turns Krakenoid visible. His opponent attacks him with his claw though. Krakenoid then cloned himself and attacked him brutally. Marucho then opened up heptagon mixer causing his power to increase. He then used Abyss Cyclone to attack. However, the battle was interrupted by Zenthon before he could defeat him. He later attempted to battle Zenthon by using fear stream on the robot which caused no damage. He then used hyper stream which proved useless. He was then defeated in one strike. The battle resulted in a draw.

In Fall From Grace, he battled Zenthon alongside Titanium Dragonoid and Taylean before Zenthon flees and later he watched Titanium Dragonoid's and Taylean's battle against Spyron and Vertexx.

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.

In Agony of Defeat, he and Taylean briefly fought against Drago using Core Bunker and Root Core - Battle Bastion to protect Bolcanon and Krakenoid from Thor Buster. They then noticed Drago was acting like a savage.

In BakuNano Explosion, he battled the Bash Brothers and their Darkus and Pyrus Flash Ingrams and won a bit. Marucho (possibly) used Hold Over to prevent the Bash Brothers from moving and using any abilities until the battle's over, but he and Tristar lost due to them using their BakuNanos causing Shun and Taylean to beat them in their place.

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, Tristar 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, Tristar made interference and transported them to safety. As a result, Rafe and Paige decide to stick with Marucho's strategy, and Tristar 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 Triple Threat, he and Taylean battled Horridian and Bolcanon in the finals match. Both his opponents used their Bakunano giving them a hard time. Taylean later took Bolcanon out. He and Taylean were ready to take out Horridian when the battle got interrupted by Mag Mel's Chaos Bakugan invading Interspace.

In Interspace Under Siege, he helped battle the Chaos Bakugan and later used his BakuNano, Crosstriker.

In Gundalia Under Fire, he was shown to be happy to return to Gundalia.

In Battle Lines, he used his Mobile Assault Vehicle for the first time.

In Unlocking the Gate, Dan and Drago gave Tristar and the others a piece of their power which enabled them to call their Mechtogan.

In True Colours, he helps Drago fight against Anubias's Bakugan by using Crosstriker.

In Dangerous Beauty, Tristar 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, Tristar parted ways with Marucho. However, rather than returning to Gundalia, he opted to live on New Vestroia instead.

In Blast From the Past, he helps the Bakugan from New Vestroia to defeat Mechtavius Destroyer, but he was only shown briefly and destroyed quickly by Mechtavius Destroyer.

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.
