Look at picture for now.

Powers & Abilities

Rulk has a massive amount of strength and durability. Rulk is able to lift 1000 tons with one hand. Rulk can also withstand being hit with an entire planet, and not be fully injured.

Rulk has the ability to regenerate on command, so even if his head gets sliced off, he can regenerate from that. If his whole body is destroyed with no full piece, he can also regenerate from that, but it would be slower. Rulk can generate an infinite amount of organic stone, in which he can form giant fists from the ground if he wanted to, an entire castle made of stone, and many more. This ability is similar to Diamondhead's. The infinite amount of stone also helps him regenerate. Rulk is able to duplicate himself as well, but it's difficult.

Rulk has an immunity to various things, such as various gasses, venom, acid, and even being frozen and melted. In fact, being melted/heated gives him an advantage to burn you himself.


Rulk is very vulnerable to magic and lasers. Those can hurt him very much, to the point where he can't regenerate.

Rulk is not very intelligent, and that can cause him to make dumb choices. He can also rush into violence sometimes because of his poor intelligence.
