FireLord

Real Name: Pyreus Kril
Group: Heralds of Galactus
First Appearance: Thor #225 April 1974

Pyreus Kril was serving as first naval officer aboard the Xandarian explorer ship Way-Opener when his commander and friend, Gabriel Lan, was unexpectedly abducted by a teleportation beam. Vowing to rescue him, Kril assumed command of the Way-Opener and began to pursue the ship of Galactus that transmitted the beam. Much later, Pyreus Kril caught up with him and boldly teleported himself aboard Galactus's ship, demanding the release of his former commander. Galactus was impressed by the Xandarian spaceman's determination and offered to tell Kril of his commander's fate if he agreed to become his new herald. Kril agreed and was transformed by the power of Galactus into Firelord. Kril learned that Lan had also become a Herald of Galactus, known as Air-Walker, but ultimately passed away in defense of his master. Galactus had created an automaton of Air-Walker, but that too was destroyed. Though Galactus kept his side of the bargain, he suppressed the knowledge he had given Kril so that he might send him on a mission to Earth.

After defeating the mad living planet Ego together, Firelord was released from active service to Galactus when the Earth god Thor offered Galactus the Asgardian construct called the Destroyer in exchange for Firelord's freedom.
