Omnitraxus Prime

Omnitraxus Prime is a side member of the Starco Avengers. He is the stand-in for Wong in the EBA Edited Universe.

In the EBAEU
Omnitraxus is first introduced in the War for Starco. He is with Star Butterfly when Alex Hirsch arrives on Earth to warn of Daron Nefcy's imminent arrival. The three of them meet up with Adam McArthur in time to face off against two of the Children of Daron. Omnitrax fights alongside Star against Ostar while Adam battles Kellco.

The two magic users work together against the ship, but Ostar manages to knock out Omtitrax and take on Star one-on-on. Omnitrax doesn't get back up until after Star is kidnapped, but he is still able to save Adam by stranding Kellco.

He is currently still on Earth. He may have survived the Snap, but like the other survivors he doesn't feel lucky about it. His fate will be revealed in Daron's Endgame.

In SvtFoE
In the show Star vs the Forces of Evil, Omnitraxus is one of the members of the Magic High Comission. He is in charge of maintaining the order of space-time (as opposed to Father Time, who's in charge of regular time).
