Son of Satan, aka Helstorm, aka Daimon Hellstrom (and at least seven other aliases) is the son of Satan (duh!). More specifically, he is the son of Marduk Kurios, Marvel's version of Lucifer. You'd think that considering his parentage, he'd be a bad guy, but he's not. He's one of the good guys. And he's also constantly shirtless! Thanks to Robert for sharing the following scans with us.
