governmentninja - Leon's name is fairly self explanatory. As he basically is ninja (who prefers high caliber weapons) in the employ of the Federal Government.

imperious_lex - Lex's name is a play on Namor's battle cry "IMPERIOUS REX", which loosely translates to "Power of the King" or "Powerful King", so it sort of means "Powerful Lex"

lil_hellion I actually didn't create this journal. Someone else at another rp did, but handed it over to be since I wanted to play the character and they weren't using it. But Julian's codename is Hellion, and Lil' Hellion describes his personality anyway.
