Taneleer Tivan is the head of the Tivan Group, and renowned as the keeper of the largest collection of interstellar fauna, relics and species in the galaxy, operating from the Knowhere port installation, which lead him to being widely known by the moniker of the Collector. Through his dealings with Asgardians and the Guardians of the Galaxy, he was in possession of one of the Infinity Stones and was nearly able to obtain a second stone. However, this caused Thanos to attack his museum seeking the Reality Stone, although Tivan survived the attack. Following the Blip, Tivan sold Knowhere to the Guardians of the Galaxy.
