- Persona 2: Eternal Punishment: Persona
The Joker Persona was originally featured as a Persona under the control of JOKER during his first appearance. JOKER would continue to use this Persona until his eventual death at the hand of Tatsuya Suou.
During the time when the Joker Curse spread, people who were infected by the Joker Curse gained the ability to summon the Joker Persona (or "degraded" variation of it) as their Persona. Those who already awaken their Persona and infected by Joker Curse will have their Persona overwritten by Joker as shown in the case of Ulala Serizawa.
In the added scenario included with the PSP version of Eternal Punishment, it is revealed by JOKER that the Joker persona was modeled after Tatsuya Suou.
