History
Terrax was originally a dictator from the planet Birj, until he became Galactus' herald, and started searching out planets for his master to consume. On his way to Earth, Terrax encountered a scout vessel from the Skrull invaded Earth, he manipulated several meteors to form a meteor shower and destroyed the craft.
When Terrax arrived on Earth, he caused a power failure which freed all the suppressed heroes and Exiles, Terrax then randomly started shooting his energy beams. After seeing their people terrorized by Terrax, the heroes decided to combine their powers. Terrax was able to fend off the first waves of attackers, but then Havok and the Human Torch blasted him out of the sky, and the Banner Beast and the Thing start to beat him up on the ground. Soon, all heroes that were left standing joined the fight, and Terrax died afterwards.[1]Paraphernalia
Weapons
Cosmic Axe: Terrax wielded a cosmic axe which had several powers of its own. It was capable of emanating waves of destructive force sufficiently powerful to rent a tear in Galactus' own ship. It could also project highly impervious force shields. Since it operated independently of rock and earth, the axe augmented the scope of Terrax's power.
