The Goshoryuken is only used by those who have mastered the assassination art that it originated from, being the "great" incarnation of the Shoryuken as its name implies (as with the Hadoken and Gohadoken).
Executed by performing a Shoryuken motion? and pressing punch, the attack is a Shoryuken that strikes hard and slices. Instead of crouching before jumping, the user strikes the foe straight in the chest and jumps from a standing position. It can land for multiple hits like Ken's Shoryuken, and has the range and overall function property of Ryu's Shoryuken.
In the Marvel vs. Capcom series, some versions can emit dark purple flames not unlike Ken's fierce Shoryuken.
In Street Fighter V, executing the Goshoryuken while Akuma's V-Trigger, Dohatsu Shoten, is active adds an additional hit where Akuma slams his opponent back to the ground in a similar fashion to the Misogi or the full animation of Evil Ryu's Messatsu Goushoryu. Meanwhile connecting with the EX variant causes Akuma to execute a similar motion to the Messatsu Goushoryu except he changes hands for the second Goshoryuken, giving it a similar appearance to Oni's variation of the move.
