Wizkids Rules!

A DICTATOR THAT CARES: Sidestep. Hypersonic Speed and Battle Fury, but only if a friendly character has been damaged by an opponent's attack since your last turn.

If Big Boss Hill could gain Hypersonic Speed from another source, like a special object for example, would this special power block her from using it if a friendly character has NOT been damaged by an opponent's attack since your last turn ?

No. This source only restricts when this source grants standard powers.
