Starhawk (Stakar of the House of Ogord) is a fictional character created by the late Steve Gerber (writer) and Sal Buscema (artist). He is an antihero in the Earth-691 timeline of the Marvel Comics universe.
Stakar was fated to eventually re-inhabit his infant body, reliving his life over countless times. Because of the knowledge of things to come, he manipulated events to affect what he felt would be the best outcome, referring to himself as "One Who Knows". He made many enemies in doing so, but his tampering and guidance also led to the formation of the Guardians of the Galaxy in the 31st Century.
Upon receiving his power from the Hawk God, Starhawk identified himself and summarized his purpose.
He appears in the Marvel Cinematic Universe, first appearing in Guardians of the Galaxy: Vol. 2, where he is portrayed by legendary Sylvester Stallone, and appears as the legendary leader of the Ravagers.
