Flippy

Flippy is a green bear who was in the army.

Info
Flippy started his life in a simple town. He was called up to go to the war in which he experienced so much blood, gore, and torture that he became traumatized and developed the PTSD disorder, in which whenever he sees or hears anything that reminds him of the war, he turns evil and goes on a killing spree, killing others in cruel ways.

Although Flippy can be the most cruel and dangerous character in Happy Tree Friends when "flipped-out", in his normal state, he is considered to be one of the most sociable and kindest of characters. This is proven in several episodes where he is seen doing social activities with some of the other characters such as going to the movies and playing hide and seek. In most of the episodes where he appears, he is shown as a friendly individual before he goes insane, or as many people say, "flipping-out", hence his name.

Recently, Flippy has been able to control himself, but then he shit him self 5000000 times after he did before after realizing his dark side and fighting it off in a canonical episode.

Deception in fanart and R34
Flippy has been liked by many fans over the years and he is often the base for HTF fanart, fanfictions, and fan characters. Because of this he is considered to be the most popular character in the series.

Because of this he is also very popular for R34 fanwork most of which is with his evil side. His good side is also shown but it is just usually just him being calm or blushing.
