Interesting design. It's reminiscent of her late X-Factor design, only it's all green with more skin. Normally not a fan of the straight short hair, but I like it here. It would be cool to see her hair drawn more sleek and straight when it's longer instead of stuck in the big 80s/90s style.
is Zaladane still Lorna's sister too?
Zaladane is one of those big question marks hovering around Polaris. Given that her relationship with Magneto can potentially be explored soon in the pages of Legacy, it is doubtful that the Zaladane angle will be addressed anytime soon. My thoughts? Yes, she is her half-sister, via her mother.
No, she's not Polaris's sister. It was never confirmed.
