Strange Tales, Vol. 1 #150 (Cvr A) (1966)

Hydra Lives! / The Conquest of Kaluu!
"Hydra Lives!" - Fury is strapped in a vibration buffering machine, intent to ensure S.H.I.E.L.D. can defend against the sonic attack of an overkill horn. He survives the test, but lands himself in a wheelchair while recovering. In his recovery, he accepts an invitation to a party hosted by Don Caballero, the suspected head of a reborn Hydra. "The Conquest of Kaluu!" - Strange and the Ancient One travel into the past to retreive the book of the Vishanti, in hopes that it will provide a defense against Kaluu's attacks. Their defense proves successful, but the threat of Kaluu is nothing compared to the oncoming threat of Umar.
