One of the castles on the MARVEL side is
THE THING

Ben Grimm, the Person :

Ben Grimm is the hideously misshapen monster known as the Thing. Once a World War II veteran and ace test pilot, his life was changed forever on that fateful day when he was goaded by "Suzie" to fly Reed's ship. Sue even gave him his frighteningly appropriate name; "Ben's turned into some kind of a -- Thing!" Early on (and between issues #238-245) Ben was a lumpy Thing, unlike the rocky Thing we now know and love. Also, early on he was depicted as something of a monster with an incredible temper. He never truly got over being the Thing, although he did calm down -- a lot. Reed once theorized that Ben could change between his human form and the Thing at will. However, Ben subconciously believed that Alicia Masters loved him only because he was the Thing, and therefore his subconcious blocked his ability to become human again.

Ben took leaves of abscence from the Fantastic Four occasionally. All were over a short period of time with one notable exception. He left in Issue #264 (Secret Wars I #12) to stay on the Secret Wars planet, where he was able to change back and forth between the Thing and Ben Grimm at will. Alicia Masters first appeared along with her step father, the evil Puppet Master, in Issue #8. She and Ben fell in love, and became one of the best examples of "opposites attract." She is a gentle, blind sculptress, while Ben is a large, powerful sometimes brutish monster. When Ben left in Issue #265, Alicia (who was actually Lyja in disguise) fell for Johnny. When Ben returned, he was furious and decided not to stay. After the revalation in Issue #357 that Alicia was in fact Lyja, she and Ben were never really reunited.

Ben Grimm, the Superhero :

Superpowers :
Strength Level : Can press 85 tons
Can withstand great heat, cold, and pressures
Can hold his breath for upwards of 10 minutes

Obviously, Ben's strength is his greatest asset. Strength is really the only super ability he possesses, all other apparent abilities are merely an extension of his incalculable strength.
