Bot mode: Huge. Almost the size of the Savant when laying down.
Alt-mode: a C-130 Gunship
Bio: Nothing bothers Airstorm. Lose your energon inside of him? He'll ask if your all right. Lose your temper and put a dent in his side? he'll ask if your foot is alright. Nothing can ruffle his feathers. He lives inside the Hangars of the Salvation and hasn't been to most of the ship. His head is about 3 yards from the roof of the hangar's when he's in bot mode.
