Thanks to eBay seller
steven99888, we have what appears to be some new looks at the upcoming 3.75" X-Men figure boxset from Hasbro. The thing to note is it appears some modifications to the Storm and Nightcrawler figures have been made to differentiate them from their comic 2-pack counterparts previously released. Nightcrawler now appears to be partly transparent giving him the appearance of being in mid-teleport and storm has some added paint modifications made to her.
The last time we got any kind of official look at this set was last year at the New
York Comic Con. The set is slated to include figures of the X-Men based on the classic comic book Giant-Sized X-Men #1 and include figures of Warpath, Nightcrawler, Cyclops, Wolverine, Storm and Colossus. The images shown below from eBay may not represent the final released versions or could of these figures or could represent some type of variants, though it would be very unusual to do variants for figures in a boxset. The figures shown below include Nightcrawler, Storm and Warpath. Not shown here are Cyclops and Wolverine.
