He was portrayed by Michael Rooker who also played Merle Dixon.
In 1988, Yondu went to Earth on a delivery mission to take Peter Quill to his father, but instead of doing that, he kept the boy and trained him to be a Ravager. Over the next 26 years Yondu developed a close fondness of Quill, despite never showing any of his affection.
Guardians of the Galaxy
Yondu discovered that a mysterious item called the Orb was located on Morag; he was offered a great fee if he retrieved the item for Broker. However when Yondu arrived onMorag, he discovered Peter Quill had taken the Orb for himself.
Yondu was furious and phoned Quill who did not deny he had taken the Orb but refused to give his location before hanging up the call. Yondu issued a bounty for Quill's capture; when Yondu said he wanted Quill alive, this lead to an argument with one of his men and Yondu assured his men that once he had Quill, he would kill him himself.
Yondu and Kraglin Obfonteri traveled to Xandar to meet Broker. Yondu admired some of the strange artifacts that Broker had for sale. However, he made his true intentions known quickly when he drew his arrow and aimed it at Broker's head while mocking him. While Broker was scared for his life, Yondu forced him to reveal that the Collector was the person to whom he planned to sell the Orb.
Yondu and the Ravagers traveled to Knowhere and quickly found Quill, who was also being attacked by Ronan's Sakaaran soldiers. Quill was able to briefly get away from Yondu by piloting a mining ship.
When Quill gave his location away to save Gamora, Yondu quickly abducted the two on his ship. Yondu initially planned to kill Quill because of his many betrayals. He aimed his arrow at Quill's throat and prepare to execute him, but when Quill convinced him that it was possible to steal from Ronan with the insider knowledge provided by Gamora, they decided to work together to get the Orb from Ronan the Accuser, on the condition that Yondu would get the Orb once they had succeeded.
Battle on Xandar
During the Battle of Xandar, Yondu commanded his Ravagers to attack Ronan's Sakaarans; he and Peter Quill planned to enter the Dark Aster together but Yondu's M-ship was quickly shot down. He survived the crash and got out of his wreaked ship, only to discover several Sakaarans telling him to order his men to attack the Nova Corps ships. Instead on obeying, Yondu whistled and used his arrow to single-handed to kill every Sakaaran in front of him. He made it back to the city and later witnessed Ronan's death. Yondu convinced Quill to hand over the Orb as agreed; Quill agreed but managed to switch the Orb for a fake without Yondu noticing. As he left Xandar with Kraglin, they discussed how they did not deliver Quill to his father like they were hired to do, Yondu noted that he thought Quill's father was a jackass. As the Ravagers drank and celebrated the victory over Ronan, Yondu decided to open the fake Orb given to him by Quill. He was amused to discover that Quill had replaced the Infinity Stone with a Troll doll.
As leader of the Ravagers, Yondu Udonta appears as a vindictive, calculating, and unscrupulous thief. He is willing to kill, threaten, and betray if his wellbeing is in danger or he desires something of value, sometimes reneging on his employers for a benefit such as turning Peter Quill into a Ravager when he was supposed to deliver him to his father. Though he claims that the Ravagers have a code of honor, as Quill states that code is virtually steal from everyone. It should be noted that Udonta may have some morality as he stopped the Ravagers from eating the young Quill - an act which he continued to throw in his face.
With Quill, Udonta has a complicated history. As numerous of his men state, he had always been soft on him and protected his wellbeing - at times costing his credibility amongst the Ravagers but he was willing to use Quill as an example to his men, if not apologetically. Despite being a thief he has a level of trust in Quill but due to being betrayed beforehand, an equal level of mistrust. For example, taking his word in defending Xandar from Ronan the Accuser for the Infinity Stone but vowed to kill Quill and the Guardians of the Galaxy if they double-crossed him. When granted the orb containing the Stone, he did not seem particularly angered to find out that Quill gave him a fake Orb. Quill does state that Udonta is the only family he has.
Udonta also has a habit in which he collects oddities and places them on the console of his chair. The most recent one being a Troll Doll which was given to him by Quill in the place of the Infinity Stone.
