Firelord (Pyreus Kril) image

Pyreus Kril was born on the planet Xandar, in the Andromeda Galaxy. He is a graduate of the Nova Corps Academy, the military and exploratory force of the planet Xandar. During his commission, he served aboard a Xandarian ship under the command of Gabriel Lan. Gabriel and Pyreus became friends, until Gabriel was abducted by the cosmic entity Galactus and transformed into the herald the Air-Walker. Pyreus assumes command as captain and begins an obsessive search for Gabriel. Pyreus eventually locates Galactus' vessel and confronts the entity, only to discover that Gabriel was killed in combat. Galactus tells this to Pyreus only after the Xandarian agrees to serve him as his latest Herald.

Pyreus is then transformed into Firelord, and after a period of servitude asked for his freedom. Galactus agrees on the condition that Firelord first find a replacement. Firelord travels to Earth and after an encounter with the Thunder God Thor and Hercules is freed when Thor presents Galactus with the armor of the Asgardian Destroyer to animate and use as a Herald.
