Morg is an Underrated Galactus Herald

Morg was Galactus' choice to succeed Nova, but he was far more brutal and evil than his predecessor. He had already committed genocide against his own people before becoming Galactus' new Herald and this brutality only continued in his new position. When the Surfer shows up looking for Nova, the two fight and Morg nearly defeats him. Frightened by the prospect of such a dangerous Herald, the Surfer sets out to find friends to take him on.

He recruits Nova, Firelord, Terrax, and Air-Walker to fight Morg who succeeds in destroying Nova during the fight. This infuriates Galactus who removes the Power Cosmic and allows his Herald to be destroyed by Terrax. Morg may not have lasted long, but he was horrifically powerful during his short time as a Herald of Galactus.
