Dark Energon Bomber

Dark Energon Bombers are large warships used by the Decepticons. The ships carry bombs that release Dark Energon on impact to corrupt the surrounding area of the target coordinates. They also sometimes have carriers attached to their lower hull which seekers and ground forces can use for fast transport. The bombers have two cannons on each side, which can launch missiles and fire lasers."Megatron, the Dark Energon is proving every bit as formidable as you predicted. The Autobot armies crumble before it!"
