Yondu Udonta

Yondu Udonta was a leader of an exiled faction of the Ravagers and adoptive father to Peter Quill. When Quill betrayed the Ravagers and stole the Orb for himself, Udonta led the hunt for his former ally. Eventually, Udonta caught up with Quill, but he was convinced to help him in the battle against Ronan the Accuser, who was threatening to use the Power Stone to destroy Xandar, with Quill ensuring Udonta did not get the Infinity Stone at the end. Despite losing the stone, Udonta chose not to get revenge against Quill, leading to mistrust among all of his own clan.

Udonta's clan turned against their former captain and put their trust instead in Taserface. With the help of Rocket Raccoon, Udonta got his revenge against the mutineers and destroyed his own ship. Udonta went to help the Guardians of the Galaxy in the battle against Ego. As the planet collapsed into itself, Udonta sacrificed his own spacesuit, and his own life in the process, saving Quill.
