Tetrax Shard is an alien bounty hunter from the planet Petropia, originally hired by Vilgax to retrieve the Omnitrix, but is now a trusted friend and ally of Ben Tennyson. As a member of the Petrosapien Race, he has the power to create and grow green crystals to use as weapons, shields, and projectiles. He also has a variety of weapons on his belt and a hoverboard on it too.
Battle Against Fuse
In the future, Tetrax is nowhere to be found. He was either defeated in battle, lost, or fled from Earth to escape Fuse's tyranny.
The PastTetrax is onboard Mandark's flying research facility within The Darklands alongside Samurai Jack. He is helping study the plans of Fuse, such as the weapons made of his monster's remains and super charged Fusion Matter. He is normally seen with his helmet off, but uses it in his idle pose.
History of Planet Fusion
Fearing that the Ectonurites (Ghostfreak's species) are in-league with Fuse, Ben is eager to learn more. After the hero completes the first few steps of his plan, Ben sends him/her to Tetrax. Ben states that Tetrax knows all about intergalatic affairs.
- Before the addition of multiple other nanos, he was the only fusion that gave a nano but only appeared in that nano mission.
