champions gives powers such such bizarrely high range. generally ranged powers have about 10 meters of range per point in the power. an energy blast that hits as hard as like, an average person's punch costs 10 points and therefore has a range of 100 meters.

this is a superhero game. obvs depending on the particular table people will have different power levels, but a typical attack power might be somewhere in the 40 to 60 point range. so 400 to 600 meters of range.

(however due to distance modifiers to attacks you probably won't hit anything at that kind of range unless you really optimize for it)
