"Oil Rig Hijack" is the story featured in issue #11 of Action Man
Dr X demands 20 million dollars or else he will pump the oil from a rig and set the sea on fire. If he does that, it will spread to all the other rigs and the fire would rage for twenty years, so Action Man goes to stop him.
Action Man parachutes towards the rig and avoids most of Dr X's shots, but the last one leaves him without his parachute. Action Man falls into the water, so he changes to his diver equipment. Dr X is about to pump the oil with a bomb when Action Man stops him. Dr X tries to punch Action Man with his robotic hand but hits high voltage cables instead. Action Man throws the bomb away just before it explodes and Dr X escapes with his damaged hand.
