i agree completely that is a ripoff. the xmen suffered greatly under due to fox owning the movie and merchandising rights. ororo wasn't done justice by them and since marvel didn't own them they heavily invested in other characters. it hurt her popularity tremendously.
what doesn't make sense to me though is she is know as the sun goddess in the comics so why not show her signature color as yellow? I can't help but think this was purposeful and was taken from ororo. I'm just hoping they do her justice whenever she finally appears but I'm afraid she might be very watered down version of her comic self.
