History
After the Guardians of the Galaxy foiled his plans and rescued the people of Xandar, Kang summoned a weakened Eson the Searcher from the end of time to destroy them. The Guardians, however, managed to defeat him with a Gravity Mine, and he was returned to his time.[1]
Eson's hand was later summoned by Doctor Strange to defeat Kang during the Avengers' final battle in Chronopolis.[1]
