Tsunami Kick is a move used by Baek Doo San since his debut in Tekken 2, but it is not listed due to it being treated as the first two hits of Albatross, Triple Kick Combo from Tekken 2 to Tekken Tag Tournament, or Javelin from Tekken 5 to Tekken Tag Tournament 2.
Like Kazuya Mishima's Tsunami Kick, Baek can also perform the attack with d/f+4,4 for more damage. In the Ver.A arcade edition of Tekken 2, the d/f+4, 4 variation was a natural combo, however in Tekken 2 Ver.B it is only natural on counter hit. This change was reverted when Baek returned in Tekken Tag Tournament. Baek also has the added bonus of being able to access the move during Flamingo.
