Weapon H originates from the more modern era of comics. Titles I haven't kept up with in ages. But my understanding is he's a new creation, made by combining Hulk and Wolverine DNA. But he looks cool. I don't usually like Hulked out versions of characters, but I guess it helps a bit with Weapon H being more his own thing.

Head was from the Indestructible Hulk. Had to dremel it a bit to fit properly. Sanded down the pants heavily, then sculpted on all those spike things. Claws were katanas from Marauder. Larger than what I use for other claws since they needed to scale with him. Cut and glued in place. From there, a full repaint, and all done!
