Ludo Avarius

Ludo Avarius is a side member of the Starco Avengers. He is the stand-in for Gamora in the EBA Edited Universe.

In the EBAEU
Ludo is first introduced in the War for Starco. Daron Nefcy needs to sacrifice someone to collect the Día de los Muertos mask, so she takes Ludo to the Pit of Wasted Characters. Realizing what Daron's going to do, Ludo tries to give himself plot relevance to escape, but Daron foils his plan and throws him over the edge to join Jackie Lynn Thomas, Ferguson O'durguson, and Alfonzo Dolittle in the Pit.

In SvtFoE
In the show Star vs the Forces of Evil, Ludo was the main antagonist of the first and second seasons. Although he is technically an enemy of Star and Marco, he seems to have a strange respect for them after the events of the season one finale and the Battle for Mewni.
