Omen Right Roundhouse Punch, also called Omen Wind Hook Fist, is a secret move introduced in Tekken 4 for Jin Kazama, and can only be performed when imbued with Omen power from performing Lingering Soul Omen. The Omen Right Roundhouse Punch can be considered a makeshift Electric Wind Hook Fist, as Omen Right Roundhouse Punch has all the same properties of a CH EWHF. However, because it is imbued with Omen power, just-frame inputting is not necessary.

In Tekken 5: Dark Resurrection the properties of Omen Right Roundhouse Punch changed to further distingish it from a regular Wind Hook Fist by letting it become a launcher that could be juggled from.
