The artist drew his own version of the Phoenix Force and then drew various X-Men women with it, this is just a few. Psylocke on left, Emma Frost in middle, Polaris in middle.
Though if you ask me… Lorna has a unique possibility of her own that’s just as good as the Phoenix Force. 😉
I’ve always felt Polaris would’ve been a good third case like Jean Grey and Scarlet Witch as a major event focus, and I think some people at Marvel agree or at least did at one point too. An AU version of her was included as one of the Hysteries in Fantastic Force back in 2009.
