As leader of the outlaws known as Ravagers, Yondu and his cohorts pillage their way through the galaxy, taking whatever they want for solely their own benefit.
Yondu found Peter Quill when Peter was a child. Although Yondu raised Peter as a human son, he has a less-than-perfect paternal relationship with him. Yondu also is completely satisfied with his argument against Quill for rebelling against him (his argument is he stopped Quill from getting eaten), repeating it hundreds of times to Peter for 20 years.
In 1988, Yondu was sent to Earth with a mission to take Peter Quill to his father, but instead decided to keep and raise as a Ravager.
Being in Morag, Yondu discovers Quill decided to keep the Orb and sell on their own. Later, Quill gives his whereabouts to save Gamora of imminet death. Being on the Yondu's ship, decide to work together, on the condition that Yondu would get the Orb once they had succeeded.
During the Battle of Xandar, Yondu kills many to Sakaarans with his Yaka Arrow. Finished with the battle, Peter gives him a false Orb. Later he discovers that inside the Orb is a troll doll but he simply smiles, being thrilled since he collects them.
Two months later, he while relaxing on the planet Contraxia with his Ravager Clan, his crewmember Taserface and one of the other members hatch a plan to kick Yondu out. While there, he encounters Stakar Ogord, who is disgusted to see Yondu again, and an argument ensues, in which Stakar tells Yondu why he was exiled for trafficking in kids. Later, Ayesha arrives on Contraxia to offer Yondu a mission to capture the Guardians of the Galaxy on Berhert.
Yondu and the Ravagers arrive on Berhert, and capture Rocket Raccoon who is staying with the Milano which had crashed after a battle with a fleet of Sovereign Drones. While capturing Rocket, an argument breaks out between Yondu and Taserface over Yondu's unwillingness to hand the Guardians over to the Sovereign, until Nebula shoots off Yondu's fin.
Later on the Eclector, Yondu and Rocket are imprisoned while the rest of the Ravagers dress up Grootand tease him, treating him as tgeir mascot. Taserface gains control of the ship, and kills all crewmembers loyal to Yondu. Later the rest of Taserface's members are taking a rest while Rocket and Yondu plan to escape the Eclector. With the help of Groot and Kraglin, Yondu gets a new fin (which was hidden in his room) and uses his arrow to kill Taserface and the rest of his members. Kraglin pilots the Quadrant while the Eclector blows up.
Yondu, Rocket, Groot, and Kraglin were on the way to Ego's Planet to rescue Peter Quill and his team against Ego's plan to rule the universe. After the battle, Udonta was welcomed by Rocket and Groot and joined the Guardians of the Galaxy. Later escaped with Quill as the Ego's Planet was destroyed and Ego was killed. Yondu sacrificed and died.
During Yondu's Funeral, all Ravager Clans joined forces as Yondu was brought into space. After the Funeral, Quill gave Yondu's Arrow and Fin to Kraglin and began to practice using the weapon only to end up stabbing Drax in the chest. Udonta's actions inspire Stakar Ogord to assemble his previous team including Aleta Ogord, Charlie-27, Mainframe, Krugarr, and Martinex T'Naga. The team has become the chief Ravagers.
