Well, yeah. Only in the galaxy. As a principle, the Epsilon Wave is generally only used outside of the Milky Way (where OZ's powers are significantly more limited). For example, if the U.R.H. is colonizing a planet in Andromeda, Oz can use the Epsilon Wave to instantly terraform the planet, eliminating the need for World Engines, which usually take centuries to change the climate of a planet. In combat, the Epsilon Wave can modify U.R.H. weaponry/augmentations or general attributes so that they have an upper hand against the enemy (assuming the enemy has an upper hand of any kind in the first place).
