who started the ravanger coup guardians 2

The Ravager mutiny in Guardians of the Galaxy Vol. 2 was started by Taserface , not Yondu. He leads the takeover after Yondu refuses to hand Peter Quill over, and the mutiny is later helped by Nebula.

What happens

• Yondu’s crew is working with the Sovereign at first.

• When Yondu hesitates to betray Quill, Taserface challenges him and takes over the ship.

• Kraglin does not really support the mutiny; he helps free Yondu and Rocket later.

In plain terms

If you meant “who caused the Ravager coup,” the answer is Taserface. If you meant the larger Ravager split around Yondu, that was driven by Yondu’s past actions and his banishment from the main Ravager community, but the actual on-ship coup was still Taserface’s move.

TL;DR

Taserface started the coup against Yondu in Guardians of the Galaxy Vol. 2.
