Tetrax Shard is a Petrosapien bounty hunter who first appeared in Omni-Tricked: Part 2.




Tetrax wears a shiny grey suit along with a black helmet with a small, teal triangle on it, shoulder pads and boots. There are glowing teal coloured lines in his helmet and shoulder pads. Tetrax's Petrosapien physiology can manifest through the armor, allowing him to use his powers without removing it.

As of Mutiny for the Bounty, Tetrax is now missing his left arm.


As a bounty hunter, Tetrax's motivation is solely based around money. This can lead him from helping Ben Tennyson in the fight against Vilgax to actively hunting Ben down for a mysterious client.

Tetrax believes patience is the key to success and scolded Kraab for wanting to attack Ben early on.

Tetrax is shown to be quite arrogant, viewing himself as the leader of the bounty hunter trio and thus deserving of a prestigious leadership money share.

Tetrax displays a sadistic sense of humor, responding to Ben's horrified claims of letting his cousin Gwen fall to her death as him simply "letting her go", before laughing about it.

Although he initially referred to himself in the third person, he switched to using first person later on.[1]


Tetrax was introduced in Omni-Tricked: Part 2, when he attacked Ben and Phil along with SixSix and Kraab. The trio came to retrieve the Omnitrix from Ben, so as to prevent Vilgax from getting hands on it and completing himself.

In Omni-Tricked: Part 3, he came through a portal along with SixSix and Kraab to fight Vilgax. However, when the trio was defeated they left.

In Bounty Ball, he was watching Ben as he moved the train with Omni-Enhanced XLR8, he wanted to get the Omnitrix from Ben Tennyson because "his client" wants the Omnitrix from Ben.

In Mutiny for the Bounty, Tetrax captured Ben and tried to sell him. Later he and Ben teamed up to defeat Kraab and Sixsix. He lost his left arm due to Kraab ripping it off. Kraab and Sixsix were defeated by Tetrax and Ben. Tetrax left in his ship, this time being on friendlier terms with Ben.

Powers and Abilities

As he is a Subsapien, Tetrax shares many of the same abilities as Diamondhead.


Textrax carries a laser blaster.


Tetrax's large size prevents him from easily manoeuvring himself in tight spaces, such as a train's cabinet doors.[1]  Just like other Subsapiens, he can be harmed by loud sounds, just like Omni-Enhanced Diamondhead.
