so...psylocke didn't break it? and it is manifestly NOT illusion.
that goat monk was actually jamie f'n braddock. braddock recognized it was a lie after being fooled briefly, but recognition wasn't enough to escape it, he actually had to BREAK THE REALITY fantomex created. and of course he is a reality manipulator of the tallest order.
i don't see anyway she can she through or break a misdirect when braddock couldn't, nor could celestial technology.... she could maybe trick him briefly, but between his multiple brains and his own ability to make her think she won, i don't she how she can win this thing, ultimately.
Saturn Girl herself was unable to phuck with Sensor Girl, and she's one of the most powerful telepaths in comics. Not only that, but Jackie was able to implant false memories in Saturn Girl's mind. Jackie doesn't just do mind illusions, she's also knowledgeable about magic, too.
She also has remote sensing, giving her the ability to see through illusions. Who knows if she can detect Fantomex's illusions. He better pray that she can't, because Jackie would crush him in a HTH fight.
