Frank's Jean is amazing. Probably one of the best renditions I've seen of her costume. Curious as to what the cover will be used for.
As its been stated, Eclipse is an original character, who's origin is nothing like Sunspot, and quite frankly, there personalities aren't too similar either. How many redundant powersets do we have running around the X-Men? The wells run dry when it comes to finding a unique power these days.
