"I'll see you hanged for this!"”
—Advance Wars: Days of Ruin CO Description
After the war with Lazuria is over, he orders Waylon to kill Forsythe, much to Brenner's dismay. Brenner, defiant, orders the troops to leave the area because it was revealed that Greyfield has gone mad, was the true instigator, and was shown to have a superiority complex. Greyfield fires weapons against the hiding spot after he frees the Lazurian prisoners.
With the knowledge of the Creeper being out in the public, some of Greyfield's troops abandoned Greyfield. Support from Greyfield started diminishing as he has lost control of his troops. He is then shown to have little consideration for his troops as anyone who disobeys are considered weak and traitorous.
After a campaign against him, he has failed to launch the Caulder Missiles on time. He is shot by Lin, ending his hunger for power. Greyfield (when alive) referred to himself as King Greyfield the Mighty.
