In order to quell an uprising led by his son, Filius
, the macabre Captain Omen
unleashed his most powerful servant, Aquon, to pound the usurpers into submission. Filius chose the captive Hulk
to lead his rebellion, and so the burden of facing Aquon was Hulk's alone. The massive man-fish fought toe-to-toe with the green behemoth and gained the upper hand when the Hulk unwittingly cracked the hull of Captain Omen's submarine home, flooding it. Just at home in the water as he was on dry land, Aquon swam circles around Hulk, preventing him from taking in any life-giving oxygen. Captain Omen was forced to pump the water out of his ship before everything was destroyed, saving Hulk's life, but in the process Aquon was sucked out to sea too. The Hulk held his breath long enough to survive a watery grave, but Aquon did not return.
