Cosmo was seen when the Guardians entered the Collector's museum to get info from him about a powerful object that was inside a orb. Cosmo groled to Rocket Raccoon while he passed by his jail, and he growled back. After the Collector's explanation of how the iten inside the orb, knwon as Power Stone, worked, his assistant, Charina, tired of being his slave, grabbed the stone, but couldn't handle the power, and exploded the museum, destroying many of the cages, including Cosmo's, setting him free.
In the post-credits scene, he is seen licking the Collector while the latter sadly and silently looked at his ruined collection, while being asked by Howard the Duck why did he let Cosmo lick him.
