"Dude, you're complaining about spoiler potential and then you want me to tell you what Peacemakers are?"
Um--yes :) I'm kinda finicky about spoilers. Sometimes I don't like them and sometimes I give into the temptation (like when I peeked ahead the first time I read LotR to find out what happened to the Ring).
So what are Peacemakers? :) I have a theory I'm wondering about. . .
"Geeky trivial thing: FMA is apparently how you abbreviate "Fullmetal Alchemist". I know there's no such word as "fullmetal" but that's how it shows up in the logo, and it's one word in the original Japanese (hagane)."
I have changed my tagline accordingly, since it was apparently incorrect before :)
Someone I know said they're EVAs - referencing Neon Genesis Evangelion, which I haven't seen. They're sort of alien robot-things.
