Air Hammer

Air Hammers are a race of space-borne creatures that herald over comet storms.

Biology
Air Hammers are blue and yellowish-gold robotic hammerhead sharks with wings.

Powers and abilities
An Air Hammer's skull is the hardest substance in the universe. A flock of Air Hammers can tear through a starship.

Weaknesses
Air Hammers are unable to tear through shields.

History
Forty cycles after the Ark left Earth, the ship was struck by an EMP, paralyzing the ship and its crew. Being unaffected by the pulse, Arcee and Grimlock used an Autobot shuttle to guide the Air Hammers away from the Ark.

After the Great War ended, Cybertron was invaded and conquered by the Quintessons, who locked the Cybertronian populace within a virtual reality simulation. The only way to escape from "The Loop" was by transformation, so Perceptor hacked into it and summoned a flock of Air Hammers. The beasts' presence scared everyone into transforming, there by setting them free from the Loop.
