Pyrokinesis: The Human Torch possessed the mental ability to control ambient heat energy and the physical ability to transform his entire body, or portions of his body into a fiery, plasma-like state of will. The cells of a normal human body convert energy from foodstuffs into a form of energy usable by the body, adenosine triphosphate (ATP).

Among other mutagenic changes, the cosmic ray bombardment triggered a specific genetic code rearrangement that caused the Human Torch's ATP production sites to generate a new form of energy containing molecule. (Reed Richards has dubbed this molecule adenine ribo-heptaphosphene, AR-HP.) This complex molecule not only provides ordinary bodily energy but contains large stores of latent chemical-bonding energies. Another favorable mutagenic change are his cells' ability to utilize this extra energy by converting it into a moderate-density, plasma-like state that is regulated by a subconscious mental field and can be modified by an act of will. When sufficient quantities of energy are consumed, the Torch unavoidably reverts to his solid state.
