1. No, Sailor Neptune has one too, and I think I might have more, but I'm not sure. Feel free to request, though!
2. Yes, that's all they do. I haven't figured out any more complex interactions yet.
I'll leave the creative side to you unless you're wanting more than a character name that I'm interested in. Let me know if the names need to be spot on like with the girlsx files:
Black Cat (Spiderman Version, not DC)
Cecile Croomy (Code Geass)
Cornelia li Brittania (Code Geass)
Euphemia li Brittania (Code Geass)
Garnet til Alexandros (FFX)
Hell Knight Ingrid (Title same)
Mary Marvel (DC)
Ms. Marvel (Marvel)
Olivia Mira Armstrong (Metal Alchemist)
Rangiku Matsumoto (Bleach)
Riza Hawkeye (Metal Alchemist)
Arias Oaks (FF Tactics)
Spider Woman (Marvel)
Cassandra and Sophitia Alexandra (Soul Calibre)
Fiona Belli (Castlevania)
Supergirl (DC)
Any of the above, not necessarily alll. No idea how long it takes you to imagine and code one of these. Thanks!
