Magik

Magik (Illyana Rasputin) is a teleporting mutant who was sucked into the demonic Limbo dimension as a child (great job babysitting X-Men!). Growing up there as a slave of the demon Belasco, she learnt both good and evil magic. Ultimately creating her Soulsword from... well part of her soul. She also began manifesting more and more metallic armor over her classic New Mutants costume, kind of like the ultimate in over-accessorising.

Invisible Woman

The Invisible Woman (https://en.wikipedia.org/wiki/Invisible_Woman), or Sue Storm, is an original member of the Fantastic Four. The prototype rocket ship crash and space radiation that gave all the Fantastic Four their powers (rather than say, death or a bunch of cancer), endowed her with the ability to turn herself and other objects invisible and generate similarly invisible force fields.
