Flippy

Flippy is a green bear who is a war veteran.

Not much is known about Flippy save that he served in a war (presumably against a country of tigers, as shown in Operation Tiger Bomb), and that, perhaps as a result of traumatic events during the war (such as the deaths of his teammates) he developed a split personality known as Flipqy.

Whenever Flippy hears or sees anything that reminds him of warfare or combat, such as the sounds of popcorn popping, or an alarm bell ringing, he "flips out" and switches over into his alternate personality, who then kills everyone in the vicinity (perhaps because he perceives himself as being in a combat situation and mistakes everyone else as an enemy combatant).

Whenever he switches back into Flippy, he usually has no memory of what happened, and usually does not acknowledge the bloodshed that his split personality caused

(Do not compare his "split personality" with either Post Traumatic Stress Disorder or Dissociative Identity Disorder. His "split personality" schtick does not match any description of actual PTSD or DID in the DSM-IV and is more akin to something out of a Hollywood slasher flick. Needless to say, it would be unfair to real, actual sufferers of these mental illnesses if you compared them to a murderous green cartoon bear or to any other kind of Hollywood Psycho)

Normally, Flippy's "flip-outs" last for the duration of the episode, during which he is an unstoppable killing machine. As of (and during) the canon episode "Double Whammy" Flippy has been shown reverting back from his evil personality more often (and his split personality has even been seen FAILING to kill people), suggesting he has a better degree of control over his flip-outs.

He is the most popular character on the show, as according to official "character tournament" polls held by MondoMedia in mid-July 2013.

The effects of this popularity can be seen in the number of fan-characters who are romantically or otherwise paired up with him (examples: Ale, Martyna, Gaby, Lucky, Mahogany, Paurii, Cindy, Yooriliz, etc.), and the number of fan-characters who are  also given military apparel and backgrounds/are modeled after him.

However, a vocal and significant portion of the fandom looks down on fans who model their OCs after Flippy or pairs up with him, derisively referring to such fan-characters as "Flippy-Sues" (a contraction of "Mary-Sue" and "Flippy-Sue"), and are also disturbingly fixated on condemning and hating "Flippy Sues" as much as possible.

This negative attitude towards "Flippy-Sues" is so pervasive in the fandom that many have ceased to make military-themed fancharacters and/or pair their fancharacters up with them, and many have made joke/parody Flippy-sues in response to the trend

As of recently, the parody and joke Flippy-Sues have far outnumbered the genuine ones, so it's safe to say, that the fandom's fixation on condemning and hating them something akin to beating the proverbial dead horse.

Flippy is most often shipped with Flaky by a large number of fans, who claim that there is canonical evidence of this pairing- Flipqy seems to avoid directly killing Flaky in most of his appearances, and Flaky once threw Flippy a birthday party, and in Double Whammy, Flaky's screaming was what snapped Flippy out of his flip-out.

Mondomedia may or may not be aware of the popularity of the Flippy/Flaky ship, as they ended up competing with each other in the final round of the character tournament poll in Mid-July.

Naturally a lot of fans also like to speculate what sort of children they would have. The most popular and notable depictions of the results of a Flippy/Flaky coupling were drawn by Chama (artist of HTH: Happy Tree High)- In his pictures Flippy and Flaky have two kids which are the opposites of their parents: a small red porcupine with Fliqpy's eyes and attitude who apparently bullies its sibling, a small green bear bear who is constantly crying but likes to be cuddled.

In deadlydark's comics, Flippy is afraid of boats.
