Digital Devil Saga: Avatar Tuner

 * Tribe: Embryon
 * Atma Avatar: Agni
 * Atma Brand: Fireball
 * Brand Location: Right Arm

Heat is Serph's unofficial second in command. His right arm is emblazoned with the "Fireball" Atma, which allows him to transform into Agni. Tough and fierce like his personality, his transformation Agni is big, red, and has two snarling mouths. Before the awakening, Heat would dutifully carry out any order, but once the Atma appeared he found it hard to control violent feelings of anger. He watches Sera closely, and is at times bothered by his feelings toward her.

As a human, in battle he uses a grenade launcher. As Agni, he is strong against fire attacks but weak against ice attacks. His statistics emphasize Strength and Vitality, with a significant weakness in Magic.

The Two Princes
The four Embryon members arrive at Coordinate 136, which resembles a tourist attraction. A story is told as they ascend the attraction (which resembles a large mansion) in the style of a fairy tale. It grows more twisted as they reach higher levels, which is a reference of the connection between Serph Sheffield, Heat O'Brien and Sera.

Digital Devil Saga: Avatar Tuner 2
Heat is a member of the Embryon who is separated from the others when they emerge into the real world. His right arm is emblazoned with the "Fireball" Atma, which allows him to transform into Agni. He finds his way to the Karma Society where Margot Cuvier convinces him to side with them so that he may have his revenge against Serph. Violent in nature, Heat seems to be unsure how to express his conflicting emotions towards Serph and Sera, so his feelings manifest themselves as anger. He is later heard to be wailing in despair in the EGG Facility, and openly encourages the party not to die while fighting them.

After defeating Serph, he absorbs the power of the EGG in an attempt to become a god, contaminating the entire facility and transforming into Vritra. He is mortally wounded when Serph (as Varna) bursts out of his body, and he dies soon afterwards. His data is sent to the sun, and depending on the dialog choices made by the player over both games, he will either join Seraph for one final battle or allow Roland to take his place. As he is not able to reach enlightenment, he is reincarnated.
