Hybrid Form
When transformed, the Flamethrower Hybrid has his head transformed into three huge fuel tanks while his neck becomes a jumble of metal parts. The Flamethrower Devil Hybrid's arms transform into giant flamethrowers that serve to attack his enemies.

Personality
Flamethrower Hybrid's personality is currently unknown, as he was mind-controlled during all of his appearances. However, he taunted Denji before setting him on fire and was observant enough to notice that he was weakened in the final fight.

Control Devil arc
After Makima commanded her agents to attack. The Flamethrower Hybrid along with other hybrids pulled out their weapon, transforming themselves into their hybrid forms, and lunged at Denji. As each makes contact with him, they are blown back by the force of him leaping forward.

After Chainsaw Devil defeated Katana Man, the Flamethrower Hybrid appeared on the floor below Denji in the building and aimed his two flamethrowers at the ceiling, firing and generating a huge explosion of fire after which Chainsaw Devil was attacked by the other hybrids and sent off Earth by Makima, but he managed to come back and cut them all in half.

He reappears in the final fight where he sets fire to several zombies that were around Denji in an attempt to kill him, however Denji escapes the attack and cuts the head of the Flamethrower Hybrid in half.
