Fliqpy is the main antagonist of Happy Tree Friends, and the split personality of Flippy. Evil Flippy, hereafter Fliqpy, is Flippy's violent alter ego and the main antagonist in the Happy Tree Friends series (he also appears in its spinoff miniseries Ka-Pow!). He is considered one of the most popular characters of the series. However, Fliqpy's appearances are rare, to keep his behavior from becoming repetitive. According to writer Warren Graff, Fliqpy is based on John Rambo.
