Background story: Razorclaw-led Predacons were surrounded and ultimately defeated by combined forces of Defensor and Dinobots. Their sparks were detained on Garrus-9, a spark prison for Cybertronians, guarded by Fort Max. But then, Megatron ordered a small Decepticon covert-strike team, consisted of Astrotrain, Soundwave and Stunticons to infiltrate Garrus-9 and retrieve the Predacon's sparks, and also, a spark of Decepticon criminal, Bloodscythe (my own imagery character). The mission was a success, Fort Max and the defending Autobots were unaware of the sudden strike by the Decepticons. Back on Kaon, Shockwave and Thunderwing, under supervision of Lord Megatron, created six new bodies for the now-deceased / currently-disabled Predacons + Bloodscythe. They'll be re-designated as Dinocons, while still retaining their Gestalt technology, to become Dinoking.
