Are Colossus and Negasonic Teenage Warhead or other characters aware that Deadpool is breaking the 4th wall?
Users have the capacity to be aware that their Universe is false. Through this, they may be able to carry out acts that, within the Universe, would otherwise be impossible. Depending on the extent of the user's power, one could potentially gain the powers of Reality Warping and/or Omniscience within the context of their own false Universe.

So if the 4th Wall Awareness super power is canonical, are Colossus and Negasonic Teenage Warhead aware that Deadpool is breaking the 4th wall? Or do they just think he is crazy and talking to himself?
