Yeah, Kiril is really more of a support character. Though bear in mind that he's quiteaspects, cunning, and could likely hold his own in some scenarios surprisingly well. Perhaps given some instruction by the more experienced crew members, he can grow to be very versatile. As you watch Guardians of the Galaxy, think of him filling a role somewhat similar to Rocket Raccoon. 

Though I do plan on having him develop in other aspects, as basically pointed out in my sheet. If it's any further indication to what my plans are, I'll say that a major inspiration for Kiril was Amuro Ray from Mobile Suit Gundam.
