—Thorak, various episodes
Thorak, Zorak (ゾラック, Zorakku?) in the Japanese version, is Jaakor's Mechtogan and is also the second Mechtogan used by Shun Kazami in Bakugan: Mechtanium Surge. He is a 2-in-1 Mechtogan along with Flytris and when they combine, they can form Duomechtra.
He appears in The Eve of Extermination, where he was summoned by using Dragonoid Destroyer's energy. He also combined with Flytris to form Duomechtra and defeated Mechtavius Destroyer.
In Evil Evolution, he fought against Mechtavius Destroyer alongside the Brawlers. He formed Duomechtra with Flytris but was defeated easily.
Aquos, Darkus, and Haos Thoraks made brief cameos in End of the Line.
Thorak is #16 in the Mechtogan toy line. Aquos Thorak has 210 Gs.
- Whenever he attacks with his dragon-like head, he says: Chain Dragon. Whether or not this is an Ability Card or simply a catchphrase is unknown.
