Biography
&nbsp Flippy was originally a soldier in the Vietnam war, who suffered the trauma of the deaths of his partners. Since then, he has developed Post Traumatic Stress Disorder (PTSD).

pisodes where he appears first depict him as a friendly character. If exposed to anything that reminds him of warfare (weapons, gun-like sounds, etc.) he would flip out - hence his name - and kill anyone around him. His flipped out form is usually accepted as Fliqpy.

Flippy has no idea of his kills after he reverts back. In the episode Double Whammy, he found out and went to seek professional help. In Part 2 of the episode, he came into a battle with his evil self, soon discovering that he was just making it up in his head. After defeating his evil self, Flippy seemed to be cured, though was killed at the end of the episode. Fans believed that Flippy was cured of his illness from that episode, though his later flip-out in the short On My Mind dispelled the rumors.
