Seen in the public eye long before he met the Mighty Union, his first run in with the team was in Las Vegas, during Psyman’s stag-do.
Responding rather rapidly to the news of “Banana Man’s” attacks, three members of the Pantheon, led by Raijin, turned up just as the Union had cornered the brainwashed Psyman. Witnessing Half-Life firing into a crowd of civilians the three attack him. Ignoring Acolyte’s cries of misunderstanding, the three kept attacking but were quickly defeated by the Union.
Unknown to the three of them, they were then taken captive, and held until the Union had saved Psyman, who then changed their memories of the exact details of the fight, only remembering they had attacked the Union on sight.
