Executed by performing a Shoryuken motion? and pressing punch, Sean performs his version of the Shoryuken. The execution depends on the game.
In New Generation and 2nd Impact, Sean performs a fairly standard Shoryuken but executes a punch at the apex of the attack that slams his opponent back to the ground. In 3rd Strike the move has been changed to a double-handed smash punch that is swung upward.
