Lythirus (リズラス, Risurasu?) is a lobster-like Bakugan. He was the Guardian Bakugan of Stoica, a member of the Twelve Orders. He was insane just like his master.



Lythirus is partners with Stoica of the Twelve Orders. He is a ferocious and savage Bakugan, whose style is a combination of insect and reptilian fish. Lythirus can cut anything up with his big scissor-like hands. He is usually calm, but once he gets angry, he goes on a destructive rampage. He is obsessed with winning and he will use any dirty trick to get the job done. His Battle Gear is Razoid.


Lythirus is normally calm, but he will go on a destructive rampage when angry. He is not above using any dirty tricks to win due to his obsession with winning. However, despite this, he did had some sense of honor, as seen when he call Plitheon "lower than scum" for turning his back on Jesse Glenn. He gets along with his partner Stoica, seeing how the two work together.

However, he has been proven to be insane, going as far to used the ability to drown his enemies despite the fact that he will drown his allies as well. He is loyal to the Twelve Orders, including his partner Stoica and Barodius, and Dharak as well. This shocked Lythirus when Phantom Dharak betrayed them by killing him and his partner along with Dragonoid Colossus.


Bakugan Battle Brawlers: New Vestroia

Lythirus was first seen in Final Fury, in the video which Professor Clay received from an unknown source, along with Dharak, Krakix, Lumagrowl, Sabator, and Strikeflier. They were at war with the Castle Knights of Neathia and beat them all.

Bakugan: Gundalian Invaders

Lythirus made his official debut in A New Beginning; he appeared along with the rest of the Twelve Orders' Bakugan during Dan Kuso's vision. They all were showing battling the Castle Knight's.

He appeared again in The Sacred Orb where he aided the rest of the Twelve Orders against Neathian forces by encountering a group of Nastix's and beating them by using Acid bath. He later fought Akwimos taunting him that he can't wait to destroy Gigarth. The two battled in the water then came out. Akwimos used Spiral Pressure causing Lythrius to use Megalow theria which ends up doing major damage to Akwimos. He ends up gaining the upper hand, that is until all of the Gundalian forces were transported back to Gundalia by the Sacred Orb.

After forcefully being transported out of Neathia, Barodius has Airzel, Stoica and Kazarina lead the next fleet. In The Secret Switch, he fought in the second round during the brawl between Dan, Fabia, Jesse, and Stoica. Lythirus had Aranaut on the ropes but after Plitheon joined the fight, the two were put to shame by Aranaut's Battle Gear, Battle Crusher. Later during the third round of the brawl, both he and Plitheon managed to really make a comeback on Aranaut; that was until Hawktor joined the fight and really put the two Twelve Orders in a tight spot. Stoica, seeing that they must win the brawl to prevent the Neathians from raising the second security shield, summons his Battle Gear, Razoid, and equips it to Lythirus, giving the Twelve Orders a temporary but minor comeback into the battle. However, due to the Battle Brawlers superior brawling skills; the battle results into a loss for Gundalia.

In Curtain Call, he, along with Lumagrowl, appeared to attack by using his claws, defeat and dispose of Plitheon as punishment for escaping and for saying he wanted to leave Jesse Glenn. During the punishment, he even cunningly remarked that Plitheon was "lower than scum" for turning on his battle partner, Jesse.

In Colossus Dharak, after Kazarina announces that she has finished upgrading Exokor, the rest of the Twelve Orders attack the Neathians in order to clear the path for Dharak Colossus to destroy the second shield. He and Stoica send out Scaboid and Megarus to attack Akwimos and Coredem. When the two beat them Stoica equips him with Raizoid and together him and Kraxix use their battle gear ablities and deadly inferno on Coredem and Akwimos causing them damage.

In Draganoid Colossus, He battled Akwimos who used his battle gear ability on him which he counters by using Merfock. Akwimos then uses loop defense though the water has no effect on him. He then uses Megalo theria which burns Akwimos and knocks him out winning him the battle. He and the others retreat when Linehalt uses his powers.

He makes a later appearance in Redemption, where he and Lumagrowl battled against Sabator and Aranaut. At first, they seemed to have the upper hand until Nurzak managed to give Fabia a few pointers that she could use to her advantage against Lythirus. Plitheon, Contestir, and Phosphos arrived to aid Stoica and Kazarina. Stoica then activated Death End Merman that flooded the whole entire battlefield which gave Kazarina and Stoica the victory.

In Final Strike, he and Stoica ambushed Shun and Fabia as they tried to rescue Dan and ended up battling Hawktor and Shun. The battle lasted till Dream Escape, where the it ended in a stalemate due to the Battle Brawlers escaping.

In Gundalian Showdown, he fought Blitz Dragonoid, Hawktor, Akwimos, Linehalt, Coredem, and Aranaut along with Strikeflier, Lumagrowl, and Krakix, only to be defeated by Blitz Dragonoid.

In Broken Spell, he was seen on Neathia along with Strikeflier and Phantom Dharak battling against Blitz Dragonoid and Hawktor alongside Strikeflier, but the battle had no outcome.

In Code Eve,he finally starts his battle against Akwimos, Raptorix, Linehalt, Coredem, Hawktor, Phosphos, Contestir, Rubanoid, Plitheon, Aranaut, Avior, Sabator, Blitz Dragonoid, Dragonoid Colossus, and lots of Neathian Bakugan alongside Strikeflier, Phantom Dharak, and lots of other Gundalian Bakugan. he attacks and defeats Sabator in order to prevent him attacking Barodius. He later attacks Dragonoid Colossus and blinds him by shooting Acid Bubbles in his eyes so that Phantom Dharak could attack him. Dharak attacked and killed Stoica and Lythirus along with Dragonoid Colossus as it was easier to just finish them all.
