He was portrayed by Bradford Dillman.
Michael Sutton was a rich game hunter who owned his own private island, where he kept other animals he had imported to kill for himself. He seemed to be motivated out of sadism, given that he had decided at one point, he was bored with hunting animals and had preferred to hunt men instead. He would follow whatever man he could find and appear to them as a friendly individual simply inviting them over for the night. He'd take them there in his private jet (it's unknown as to whether or not the pilot was aware of his actions). Once they'd get there, he'd take a picture of them to hang on his wall. After having dinner with them, he'd drug their drinks, causing them to fall asleep, and then take them to the hole he'd bury them in once he killed them. After waiting a while to get ready and for them to wake up, he'd begin hunting them and put them through several deadly obstacles and traps as he does so. Through each obstacle, he'd give them a recording machine of him giving hints as to how they can survive each obstacle. He had succeeded at least 5 times, and buried them in his own personal graveyard. Although he'd supply them with food and weapons in preparation for his "game", he did not play fair, and this trait of his hinted to have been the reason as to why he'd always "win". He was also overly fond of chess.
Michael intends to continue his game with David Banner once he meets him at an airport. Impressing David with his skills at chess, as well as winning him over with his seemingly kind nature, he invites him over to his island after David's flight has been cancelled. Once they get there, he repeats the first process of the game, by drugging him over dinner and putting him in his future grave hole, next to the graves of all of his other victims. David manages to survive the first obstacle, and even avoids getting caught in Michael's net. However, this turns out to only be a decoy and he falls into his rel trap, a pit. And he tries to get out before Michal shoots him, he gets stung by a scorpion and this causes him to Hulk out. He then gets out of the hole, and overpower Michael (who is in great awe of the beast) enough to escape. When he reforms back, Michael cuts the motor to his boat so David can't get away. Davis watches him do so from a cliff and heads over to Michael's house in search of more food, only to discover that Michael had prepared for this and trapped him in his living room. Each of the doors and windows are blocked, and David has to find a key to one of them, while avoiding several other deadly traps in doing so. He's also given a time limit of 5 minutes to find it before Michael comes in and kills him. Michael waits for the time limit to reach as he watches David searching through the door's peephole, laughing as he does so. While listening to the recording Michael had placed in the room, he is given a hint as the where to key is: "When it comes to chess, I could write the book". David searches in a chess piece for the key, but to no avail. He then concludes that the key is inside a fake book of chess. He manages to find it to get out, avoiding any traps, just before Michael comes in. Michael then yells for David, telling him how impressed he was with the monster he turned into, and demands that he bring it back to fight him.
Once Michael arms himself with poisoned arrows and more equipment to get the job done easier, he tracks David down, only to find one of his recording machines. David had left it there, with his own recording of how Michael is not a true hunter, but a coward, given how a real hunter plays fair. He concludes that Michael only cares about winning, and is afraid of a fair game. Michael nearly tracks David down, but is caught in one of his own traps. However, he escapes it and chases him up to a cliff. David insists that the game is over, but Michael refuses to let him go until he's transformed into the beast, so he can kill it. David refuses to do so. Michael concludes that pain is what causes him to transform, so he whips David with the intent of making him change. He succeeds in doing so, but not before David trips and yanks the whip, only to make Michael fall and get struck in the leg by one of his posoned darts. He attempts to kill the Hulk, but is slwly dying from his wound. He then then dies, falls off the cliff, and into the river. The Hulk jumps in and carries him out. Once he changes back, David buries Michael in the hole that was left for him, and well as the cardboard gravestone. He crosses off his name and puts Michael's above his. He then arrives at the rescue boat, and plays the last recording machine Michael had left for him on the dock. Fortunately, he suspects something suspicious of it, and sails off in the boat as it's playing on the dock, in just enough time to get away from it before it stops recording and explodes.
It's possible that Michael selects his victims by challenging them to a game of chess, and decides to kidnap and kill them once they beat him. This may be hinted by the fact that Michael seems antagonized when David beats him before he invites him over to the island.
