Sky-Byte wasn't given the ominous function of "Harbinger of Doom" for nothing. Part ferocious fighter, part freaky metal shark-jet with lasers, Sky-Byte is Megatron's first choice for missions that border on the impossible. He's fast, tough, and bursting at the seams with enough firepower to handle any situation. No matter where you are, if Sky-Byte is on your tail, there's no safe place to hide.
He has an intense rivalry with the Autobot Air Guardian Jetfire, who had once been thought destroyed in battle by Sky-Byte.
