Saturated with power from the AllSpark and freed from the influence of MEGATRON, DECEPTICON BRAWL disappeared into the rugged land around the Hoover Dam. Making his way over the course of months to the most troubled spot on Earth, he adapted his vehicle mode to the new environment, went to ground and waited. Hiding in the deep desert, he soaks up energy from the blazing sun, and emerges only to satisfy his hunger for destruction by attacking and annihilating human convoys and armored columns. He is a ghost in the desert, attacking randomly and without reason, and disappearing before human air power can arrive to track him. To those living in the region, he is a myth, but to those few who survive his attacks he is a monster.
