Dragon Uppercut, called Thunder God Fist (雷神拳 Raijinken) in the Japanese version, is a move introduced in the original Tekken game and can be performed by every practitioner of the Mishima Style Karate.
Another input is 1+2+3+4~1 for Jinpachi in Tekken 5 while in Tekken Tag Tournament 2, it is buffed into 3+4~1. The follow-up attacks are however character specific (see respective articles for details). Heihachi also has an electrified version and a delayed version of the Dragon Uppercut, which in some games took the regular Dragon Uppercut's place.
When to use
The Dragon Uppercut is relatively slow, and the long crouch animation after the step-in is a sure-tell of what's to come, meaning that a standing opponent has plenty of time to see and block/evade it.
The step-in crouch is not without its advantages though. It is able to duck under all high attacks, and right before the punch itself, most mid attacks as well. This makes it a relatively good counter-attack when one anticipates the opponent to dish out a high-mid string, however, because of the often better alternatives which can also lead to juggles, the stand-alone Dragon Uppercut is rarely, if ever, used in high-level play.
In the cases of Heihachi, Devil/Angel, and Devil Jin, Dragon Uppercut will always knock the opponent off their feet, however, in the cases of Jin (pre-TK4) and Kazuya, this isn't so. In their cases, only clean hits will result in the opponent being knocked off their feet; regular hits, or even counter hits, do not, which is likely why they became able to perform follow-up kicks. However, not getting in a clean hit with Dragon Uppercut is surprisingly difficult.
- The Dragon Uppercut is very similar to the move Shoryuken (昇竜拳 Shōryūken, lit. "Rising Dragon Fist") from the Street Fighter series. Due to fact, the command input itself a Dragon Punch (DP) motion, except unlike in Street Fighter, Tekken's DP motion has a just frame set up between forward and down input.
- Jinpachi Mishima presents a different case when executing this move, as he needs to enter a stance before doing the uppercut. This is logical, however, granted that he cannot perform a crouch-dash move.
