Hope they limit it some way. Like he can only use one at a time.
@Pr: it kinda goes back to my question I once had.
If Flash can match Superman in speed (or vice versa, whatever), then if Superman can push a Moon (or Warworld, whatever), can Flash replicate it, seeing as his 'engine's thrust' is about the same?
I mean, if pushing something is a flight feat, then Flash should be able to do it too. But if it also involves strength, then up until now he couldn't.
Maybe the Strength Force enables him to 'Strength steal', lol. So cancelling out someone's strength by looking at them.
