Executed similarly to a Shoryuken, both in input and execution, Sagat jumps into the air and turns his body while hitting his opponent with a rising uppercut, although with the opposite knee raised. In the Street Fighter Alpha series, the move hit multiple times.
When Sagat was scarred by Ryu's Metsu Shoryuken during the events of the first World Warrior Tournament, he decided to create a similar move for himself. He has been seen practicing the move on a waterfall.
In the games, it can act as an anti-air attack, combo ender, or as a close-range punish, similar to the Shoryuken. However, it does not have the same priority, and a well-placed normal attack can stop the move. Tiger Uppercut also requires very close range, unless the opponent is in the air already. As with the Shoryuken, whiffing or having the move blocked leaves Sagat vulnerable as he falls.
In the Street Fighter II series, the move did massive damage, making Sagat a very dangerous opponent in those games.
