Marco Diaz (Rocket)

Marco Diaz is a member of the Starco Avengers. He is the stand-in for Rocket in the EBA Edited Universe.

In the EBAEU
Marco is first introduced in the War for Starco. He arrives with Adam McArthur and Star Butterfly (Groot) to save the heroes who were already fighting in Eclipsa Butterfly's Kingdom against Daron Nefcy's faceless army. They are able to hold off the army from reaching Pony Head, but once Daron herself arrives, the heroes are unable to hold her back and she is able to claim Pony's Horn for herself. After Daron snaps her fingers and unleashes the Six Ships, Marco has to helplessly watch as Star fades to dust in front of him.

He is currently with the surviving Starco Avengers on Earth. His fate will be revealed in Daron's Endgame.

In SvtFoE
In the show Star vs the Forces of Evil, Marco is the second main character alongside Star. He was always known as the "Safe Kid" on Earth, but he's willing to do whatever it takes to help Star and keep her safe.
