Apeface, Snapdragon, Snaptrap (Seacon commander) are all powerful enough to be considered among the most dangerous.
I would be fine with a bunch of cons who were dangerous already, then modified and upgraded as rewards for their loyalty to hunt down defectors and traiters.
And they all shared the Decepticon symbol face, so any who bearer witness knew they would never survive the day.
Everything I post is ok to print, use, copy, use for inspiration, promote world peace, change lives, etc...and so on and so on.
Rumble Eject! Operation, collateral damage.
