Tag Throws are special types of throws introduced in Tekken Tag Tournament and returned in Tekken Tag Tournament 2. Tag throws can be done by every character with the exception of Devil and Kazuya Mishima when they are teamed up together.
Tag throws are performed by pairing two characters up, the regular tag throw can be done by pressing 5+2. The first character will grapple their opponent, tag out, then the second character will attack the same opponent. Tag throws are almost inescapable. The first character's throw can be escaped but the rest of the throw cannot.
