Role in the Fantastic Four
Johnny is usually the most carefree and lighthearted of the Fantastic Four. He can be stubborn and emotional and has quit the Fantastic Four several times. He has a fiery temper and has issues following orders.
Johnny has fire based powers. His nickname "the Human Torch" comes from the fact that he can shoot fire out of his body as well as having the ability to erupt into flames without hurting himself. Due to his fire based powers fires and explosions do not hurt him. He can also fly. A few drawbacks to his powers are the fact that he requires oxygen to create flames, he can grow quickly exhausted depending on the amount and heat of fire he uses, and he always has to be focused on his powers to control them or else they go out of control.
In the current Marvel canon the Human Torch is dead, having been overwhelmed by Arthrian cultists and Kid Annihilus after defending the Negative Zone long enough for the rest of the Fantastic Four to close the gateway. Despite his death it is still likely that he will appear in Marvel and Fantastic Four video games.
His Catchphrase is "Flame on!" which he will say before being engulfed in an inferno
