Yondu Udonta and Kraglin Obfonteri traveled to Xandar to meet Broker. While admiring some of the strange artifacts that Broker had for sale, he made his true intentions known quickly using his Fin to draw his Yaka Arrow and aim it at the Broker's head demanding to know who the Broker intended to sell the Orb to.
A Questionable Partnership
Yondu initially planned to kill Peter Quill because of his betrayal with the Orb and despite Quill's attempts to explain, Udonta used his arrow controller once more and aimed his Yaka Arrow at Quill's throat and prepared to execute him, but when Quill convinced him that it was possible to steal the Orb from Ronan the Accuser with the insider knowledge provided by Gamora, they decided to work together.
Udonta survived the crash and got out of his wrecked ship when he turned around and saw several Sakaarans surrounding him and ordered him to command his men to attack the Nova Corps. Instead of obeying, Udonta calmly opened his jacket without a word and whistled; as the Sakaarans stood momentarily confused, he used his fin to control his arrow to single-handedly kill every Sakaaran in front of him, even causing one of their ships to crash and explode.
Having developed a second controller, Yondu eventually used it, with the help of Rocket and Groot, to escape captivity and kill the Ravager mutineers. He then used the controller during the Battle on Ego's Planet.'
A New Owner
Following his passing, Kraglin Obfonteri came into possession of a new controller and, while using it, accidentally lodged an arrow into Drax the Destroyer.  Later on, Obfonteri started wearing a newer version of the controller, similar to the first design, but silver. He used this in 2023 during the Battle of Earth, where he assisted the Avengers in the fight against Thanos.
- In the comics, the Centaurians have a natural crest, or Tahlei, which is supported by a bone structure. Yondu's second fin, featured in Guardians of the Galaxy Vol. 2, was created to resemble the one that he has in the comics.
