HO WAIT ANOTHER NAME
I think that Felix could just be Felix continuously of she wanted to, because Felix is a cool name and that's the species of human we've chalked her up to being. Felix is a Felix, and can probably stay that way and be on topic unless she comes up with some amazing name I would never think of.
Something with Crypto- or Enigma in the title could fit. Cryptonamer. Or, no matter how unoriginal it may be, The Enigma! 8D
I also think you should know that Alfred is probably my favorite character of all time from a superhero series, so being labeled thus fills me with mirth. lDDD
@Those of you who are going to Akicon: I'm reeeeally looking forward to seeing you guys. X3
edit: ALSO SPEAKING OF YOU, FELIX, I can't pick between being Teeko or Astrid. D8 I mean, if I did Astrid, I would be warm but then you, me and Jaqua would form a glaring triangle. We would all dislike each other. XD I think I want to be Teeko, so then at least one duo can think fondly of each other. Her outfit isn't very complicated, and it doesn't require yards and yards of fabric like my Euphemia cosplay will, either. What do you think, guys?
