History
Cal Henriksen was the first soldier on whom the Venom symbiote was tested before they gave it to Flash Thompson. The test with Henriksen was not successful because when the device was used to disconnect the symbiote from Henriksen, the detachment caused him brain damage.[1] Henriksen subsequently lost control of the symbiote and went on a rampage, forcing General Brad Dodge and Captain Katherine Glover to activate his kill-switch.[2]
