This is merely Jean Grey without channeling Phoenix, she is a very accomplished telekinetic/telepath, the soulself is still an astral projection a purely psychic construct, and can be dealt with by telepathic energy. There is a fine line between psionic and mystical energy, a powerful psi can do just about anything a magic user can do, through sheer force of will. And I thought it was the collective souls of Azar that ultimately defeated Trigon. Jean also has the advantage of telekinesis which she can use, both being psi talents their powers work at about the same speed, but Raven is only an empath, while Jean is the second most powerful telepath of her world.
Trigon was banished not destroyed then he came back and the souls of Azar channeled their power through Raven and that is how he was destroyed. If the soulself is all Raven has to offer then she hardly stands a chance against a telekinetic telepath of the highest order. (I had to edit because of my first sentence forgive my ignorant use of the english language if in fact anybody read before the edit)
only if you read up on what Jean can do, and since we're all reading there is no such thing as Jean without Phoenix. Being a telepath Jean could sense Ravens intent and crush her telekintically before she sends out that soulself, if Ravens soulself surives and goes on to kill Jean well, we all know what happened the first time Jean died, Phoenix was born.
Call me what you want, there is only one true Phoenix fanboy on this forum and I am not it, what there seems to be more than anything else are Phoenix anti-fanboys, there is not a spell in creation that can keep the Phoenix from rising or resurrecting Jean and if there is Jean can make her forget it just as fast as she can slam her ass around with telekinesis.
