'''Roxtor''' ({{Nihongo|Rockstar|ロックスター|Rokkusutā}} in the Japanese version) is a scorpion-like [[BakuFusion]]. It fuses with [[Radizen]] to make [[Betakor]]. It was released in August 2011. He is [[Mira Fermin|Mira]]'s new [[Guardian Bakugan]] in the second arc of ''[[Bakugan: Mechtanium Surge]]''.

Roxtor is shown to speak gibberish, which only Radizen and Mira can understand. He seems to care about his peers, especially Radizen, who he wants to befriend. This was shown in Combination Impossible, where he entered the battle to help out Radizen.

The speed of Roxtor's attacks makes it a worthy adversary in battle. His powerful legs and elongated claws make him a lethal monster when provoked. Roxtor fuses with Radizen to form the mighty Betakor.
