Melody- is herself the main core

Lilly- the childish schizophrenic who will play games with the antagonizer

Markus- the male spy that has paranoia and is quick to snap

Eclipse- a creation of Melody's mind that became a personality who is hot tempered

Demi- the parasite living in Melody's brain causing her to be canibalistic and immortal... (like a zombie but can still function) is quick to react with violence
