Lingering Soul Omen, also simply called Soul Omen, is a hidden move that was introduced in the moveset of Jin Kazama's new fighting style in Tekken 4 and reappeared in subsequent games.

[edit] Special Properties

Lingering Soul Omen is based on the two moves called Lingering Soul and can be considered a combination of the two. While each of the moves seperatly last 2~2½ seconds, Lingering Soul Omen last twice that (i.e. Jin is imbued with "Omen Power" for 4~5 seconds), it has the same properties as Lingering Soul during the time Jin's hands glow, and opens the possibility of using Omen moves. The concept of Lingering Soul Omen is therefor very similar to the concept of Devil Jin Possession from Tekken Tag Tournament.

Further more, like Lingering Soul, it repels all attacks.
