A dangerous and notorious Bakugan, Tremblar is shielded by sharp defensive blades. When an enemy gets in close proximity, Tremblar immediately detonates his most powerful weapon: a stinging spike shield that cuts through even the toughest of monsters.
He appeared alongside the other Nonet Bakugan in Wiseman Cometh. He barely participated in the battle, as he never attacked any of the Brawlers' Bakugan. He helped summon the evil Mechtogan and was defeated alongside the other Nonets when they lost control of Mechtavius Destroyer.
He appeared in Enemy Allies, where he battled Roxtor. Roxtor escaped the initial attack from Tremblar, but was defeated by Mechtavius Destroyer. Tremblar lost alongside the other Nonets when Mechtavius Destroyer was defeated.
He appeared in Gunz Blazing in ball form with the other Nonets. He later shows up alongside Wiseman and decided to challenge Drago, but Reptak returned the challenge instead. Tremblar gains the upper hand after he transformed into Combat Mode but was later defeated by the counterattack of Dragonoid Destroyer and Reptak.He appeared in Countdown to Doomsday with the other Nonets. He helped Volkaos defeat Magmafury and then he helped summon the evil Mechtogan and was later transported back to Wiseman's headquarters along with the other Nonets when Mechtavius Destroyer defeated Dragonoid Destroyer.
In Evil vs. Evil, he battled against Mechtavius Destroyer alongside the Nonets. After his pod is shot down and destroyed, he himself is killed and has his power absorbed by the fierce Destroyer.

- It is the first Bakugan to be one of a kind in a wave of Bakugan.
- He may be a robotic Bakugan, due to him saying he was "scanning for enemies" and "having a system malfunction" when Roxtor knocked him over in Enemy Allies.
- Tremblar's ball form is similar to Fencer's, with shorter legs and tail.
- When Tremblar's pod was destroyed, it didn't affect him at all, nor did it damage him. As a result, this proves that once it detaches from Tremblar, it acts as a single unit. Despite this, Tremblar is likely able to control it mentally.
- Tremblar is the only Nonet that can't equip BakuNano in the game.
- Tremblar is the only Nonet Bakugan who cannot fuse or combine with other members of the Nonets. This is due to the fact that he is a BakuMine, while the others are BakuFusion or Baku Sky Raiders, groups of Bakugan that can in some way fuse with other beings.
