Ratatosk Mode is when someone has multiple personalities as many as ten and as little as two. Its basically multiple personality disorder and it seems half the time to be a mean evil angry side and a calm cowardly nice side. Sometimes your eyes may turn red with anger in Ratatosk Mode. Most people would recognize this from a fun game known as Tales of Symphonia Dawn of the New World. Very similar. Also known as "RM"
