And, how do you decree energy strikes? Would a Ki-backed blow from Deimos count as energy, since Ki is the outward manifestation of a person's energy, like Chi is the inward manifestation.

Energy strikes have to be caused using a weapon which specifically states it's energy-based in nature, or through the use of an ability with the energy-based property. Rocksmith has the ability to summon lightning with his guitar as a standard attack, Bumblebee's blasters and Void's blade are energy-based weapons based on what's been written upto this point so would also get an advantage, but any other attack would have to explain exactly how they managed to become 'energised' in the narrative in order to gain this property.

Since Ki is spiritual energy, and as far as the game mechanic is concerned would be classed as Magical, you'd actually get a reduction in damage caused when using it directly. As a sidenote, since Void's blade is Magical in nature, given his choice of power origin, he'd still suffer from the power reduction, after taking into account the 2x for the use of energy attacks.

Since [i]Prototype Projectile System[/i] presumably uses Ki to help launch the 'projectile' at the target but the actual damage is caused by the physical impact of the projectile hitting the target it doesn't suffer from this disadvantage, although when fighting opponents resistant/immune to physical attacks it would be at a disadvantage.
