Pony Head

Pony Head is a member of the Starco Avengers. She is the stand-in for Vision in the EBA Edited Universe.

In the EBAEU
Pony Head is first introduced in the War for Starco. Her horn is one of the six Infinity Stones that Daron Nefcy needs to complete her plan. Because of this, Daron sends two of her Children to take the Horn. Seahorse tries to protect Pony but they are still outmatched. River Johansen, Moon Butterfly, and Baby arrive and they are able to save the heroes and protect the Horn. Together they travel to Eclipsa Butterfly's kingdom in hopes of finding it an easier place to protect Pony, but Daron sends her faceless army after them. Glossaryck works to try and safely remove Pony's Horn so that Seahorse can destroy it while the Starco Avengers battle the army outside.

Even though the heroes manage to defeat the army (with some help from Adam McArthur), Daron arrives to take the Horn herself. While the other heroes try to hold her back, Seahorse begins to destroy Pony Head's Horn to keep Daron from getting it. Just before Daron reaches it, Pony's Horn cracks and explodes, destroying Pony Head with it. Pony soon finds herself back on the battlefield, however, as Daron uses Father Time's Wheel to restore both Pony and her Horn. Pony is weak and powerless as Daron rips the Horn finally from Pony's head, killing Pony for good before tossing her lifeless form to the side.

In SvtFoE
In the show Star vs the Forces of Evil, Pony Head is Star's best friend from Mewni and next in line for the throne in the Pony Head kingdom. Many people find her obnoxious, but no one can argue that she is loyal to her best friend and would do anything for her.
