So these guys might not always be essential, but Shadowcat (Kitty) has always been pretty popular and White Queen (Emma) has been pretty important lately. Havok is just a personal favorite of mine.
I think of Kitty as being a bit younger and less experienced so I went with a little more of a basic costume. It also kind of reflects her Astonishing costume.. which was probably her best. She's changed a lot over the years, but still maintains her youth and optimism for the most part.Emma gets to break a few rules with her costume... I'm not talking about what you're probably thinking about right now. I let her be even more monochromatic than Iceman who is covered in ice, even down to having the only white belt. I debated over her X being red or white, but I wanted to keep some sort of conformity throughout the uniforms.Havok typically has a simple costume so I tried to keep my version that way. He has a little trouble controlling his power (must run in the family) so his full body suit helps contain it. I also like his big gauntlet that help focus the power because it adds some unique shapes to his character. I think part of why I like Havok is because he and Cyclops are kind of like me and my big brother... but I don't constantly compare myself with my big bro. Havok could be so much cooler if he would just step out of Cyclops's shadow instead of complaining about it. I don't know if you'll notice, but I tried to have as much family resemblence between Cyclops, Cable and Havok as I could... maybe a little more so with Cyke and Cable.
That leaves just one more character for my X-Men. Can you guess who it is?
