This is Clay The Panthers's power: Magma Manipulation (I wish there was another name for this that started with 'psi" or "psy")

having his spiritual bond with the eye of iblis allows him to tap into the power of creating and moving lava, at first he could only use it when his life was in danger or he was enraged like so:

but over time with the help of Silver he's managed to use it without the need anger or fear, still though, it's very dangerous and destructive power that's hard to control.

along with his magma manipulation the Eye grants him a casing of Thermal Resistance as a means to protect the host body that it is trying to overtake.
