I was thinking of incorporating Iceman's spiky ice armor from XML1 into MUA, but the armor doesn't work that well on top of MUA skins (in both XML2 and MUA). It works well on XML2 skins, however. So, I dropped the idea.
What you guys see here are what I have planned for Iceman long time ago. There is still room for one more skin, the 6th costume, though.
