Flippy

.He wears dog tags around his neck and a green beret with a checkered crest on his head. He is a retired veteran soldier in the Army. He fought in the Weaponized Animal Regiment (The W.A.R), and has an obsession with making booby traps inspired by the Viet Cong, as well as a flashback of his experience of being held captive by them (as seen in Easy For You to Sleigh episode). In addition, his attire seems to resemble the U.S. Army Special Forces, which played a role during the Vietnam War. As he fought for years, he was promoted to the rank of Sergeant. According to writer Warren Graff, Flippy is mostly inspired by and based on John Rambo. During the internet and TV series, it is unknown if Flippy has retired from the Army or if they are simply in a time of peace. Flippy rarely appears in the series, most likely due to his repetitive behavior in most of the episodes in which he appears. Lumpy most likely has even more kills than Flippy, since he has below 150 kills and has only appeared in 23 episodes so far.

Flippy is the only character in the series to cause the deaths of other characters on purpose in every episode which he appears, at least when he "flips out" (except for Without a Hitch and Happy Trails Pt. 2: Jumping the Shark, where he never flips out for real, and Autopsy Turvy (Double Whammy Part II), where all of his kills happen by accident). He has a severe case of post-traumatic stress disorder (PTSD). Whenever he sees or hears something that reminds him of war (e.g., gunshot-like sounds or crackling campfires), he becomes delusional and extremely aggressive, often killing everyone in sight. (It's possible he also has dissociative identity disorder as a result of his experience in war, judging from him basically becoming someone else in most of his appearances and the few instances he resisted his evil side during Double Whammy and Hear Today, Gone Tomorrow, much like a Dr. Jekyll and Mr. Hyde complex). He also might "flip out" due to anger or stress as seen in Random Acts of Silence and Happy Trails Pt. 2: Jumping the Shark. While flipped-out, several physical features about him change: His eyes turn a different color, usually green or yellow, his voice changes from high and cute to deep and evil, and his teeth become sharp. In the early internet shorts, his teeth simply became crooked. There has even been one instance where his eyes became small, circular, and with a light blue iris (Remains to be Seen). If he is in his evil state, he (along with Lumpy, The Mole, Cro-Marmot, and Nutty) doesn't have Pac-Man shaped pupils. When he is flipped out, he is known as Fliqpy.
