I'm pretty sure I read this webcomic in the 21st century. It involved a super-strong guy. He looked different, maybe made out of rock? He had a longterm girlfriend, as well as another girl who hung around (I want to say that the second girl had long dark hair), might have been living at the house. At some point, he establishes to the second girl that it's an open relationship. Some time after that (I think...), the three of them are in Disneyworld and an evil Walt Disney shows up to fight him along with, I think, a villainous barbershop quartet. Somewhere in the course of the fight, the secondary girl got bitten by a giant snake, causing the protagonist to fight more seriously. I think that she recovered eventually, but she was initially near death.
The general impression I remember was that the guy wasn't terribly heroic, that he'd prefer to just spend his life in peace, but people kept showing up to challenge him.
