Achilles Heel: Dark Avenger
Achilles heel: Dark avenger by Dragon blaze 99
The characters powers have been given by a evil creature that for some reason cannot strip the powers. So instead it sends a Dark Avenger to harass the Mega, this avenger can attacks at anytime but normal when the hero has little time to spend dealing with it. However the DA is not lethal just extremely annoying, it will slow down, pester and bother the hero. Penalties are -40% to all skills, 1/2 actions, -4 strike, parry and dodge. The appearance of the DA can be anything like shadow crows or rats but they are supernatural in nature with HF of 9 and 10 HP 2 attacks per round that does 1D4 damage. Primarily the evil creature is trying to make the mega change sides and not kill him but if push comes to shove, the force will become lethal.
