Law is a surname given to three characters in the Tekken series:
- Marshall Law (Appears in every Tekken game except Tekken 3 and Tekken Tag Tournament).
- Forest Law (Appears in Marshall's Tekken ending as a child, Tekken 3, Tekken Tag Tournament, Marshall's Tekken 5 prologue and Tekken Tag Tournament 2).
- Mrs. Law (Appears in Marshall's Tekken ending; she is non-playable).
Law is also the nicknames of Marshall and Forest. Since these two are only playable in a single game together in Tekken Tag Tournament 2, fans and other players don't get confused and it saves them the time of saying/typing their first names.
