The roster of characters for Tekken 8 has been "partially leaked" due to the conduct of test sessions

This is related to Cheat Engine, a PC application that allows players to manipulate games using various community-made scripts.

According to messages on various Tekken fan Discord servers, running Cheat Engine during the recently released Tekken 8 Closed Network Test has given players a glimpse of a partially completed roster for the game.

While some characters, like series regulars Marshall Law, Jin Kazama, and King, have already been confirmed, others like Yoshimitsu have yet to be officially announced by Namco. Fans speculate that this leaked list is likely incomplete due to the absence of Kuma, a character who has been in every mainline game in the series.

The list of characters that fans have discovered through Cheat Engine includes:

• Paul Phoenix
• Marshall Law
• King
• Hwoarang
• Ling Xiaoyu
• Jin Kazama
• Bryan Fury
• Lili
• Lars Alexandersson
• Claudio Serafino
• Nina Williams
• Leroy Smith
• Kazuya Mishima
• Jack-8
• Asuka Kazama
• Jun Kazama
• Yoshimitsu
• Shaheen
• Raven (Default Type A)
• Zafine (Default Type A)
• Steve (Default Type A)
• Alisa (Default Type A)

Tekken 8 was officially announced in September 2022 during a PlayStation State of Play livestream.
