Power Instinct
Power Instinct (豪血寺一族, Gōketsuji Ichizoku, "The Gōketsuji Clan") is a fighting video game series created by Atlus started in 1993. It is often abbreviated as PI or GI for short).
One of the innovations unique to the series was the introduction of the transformation feature. Several of the characters can change their appearance and fighting style by simply executing certain moves (usually a throwing move), though this has not been featured in every entry in the series. Other features include the ability to perform a double jump and attacking while dashing.

The first game of the series was released in 1993. In it, players play as a member of the Goketsuji clan, who are battling to determine who will replace 78-year-old Oume Goketsuji as head of the clan. It has eight selectable characters and one unplayable boss character, Oume Goketsuji, a palette-swap of her younger sister Otane. Originally, every character had a specific win quote for each defeated foe, but that was reduced to only one win quote for each character in the English version.
