When performing Spirit of Saiyans, Bardock remembers the gruesome deaths of his friends (Tora, Fasha, Borgos and Shugesh). His anger takes him over and, as he rushes towards his opponent with a "Great Ape" aura also the image, and attacks the enemy all-out: first with a punch in the gut, and then a backflip kick sending the opponent in the air. Bardock strikes them in the ground with a full power Ki Blast that is similar to the Riot Javelin, before charging a teal ki sphere around his hand as he makes a straight fist faced at the enemy, crashing down at them and inflicting massive damage. If the attack fails, he will fire an energy wave after the punch. In Xenoverse, there is a different version of this technique, Bardock charges energy in his right hand and lauches an Energy Punch fueled by Saiyan Soul at the opponent, which knocks back the opponent, Bardock then launchs an energy wave from his left hand at the helpless opponent.
Appearances in games
This attack was named Spirit of Saiyans in Dragon Ball Z: Budokai 3, Infinite World and Saiyan Spirit in Dragon Ball Z: Shin Budokai - Another Road and Burst Limit (not to be confused with another technique named "Saiyan Spirit" (or Saiyan Soul) that is the Blast 1 of many Saiyans in the Budokai Tenkaichi and the Raging Blast series). In Dragon Ball Heroes, when Akina and Goku combine their Spirit Bombs, the opponent will move away, but Bardock appears to use the punch from this attack and knock them back inside the Spirit Bomb. It appears as one of Super Saiyan Bardock's Super Attacks in Dragon Ball Z: Dokkan Battle.
In Dragon Ball: Xenoverse, it appears under the name Saiyan Spirit and is one of Bardock's Ultimate Skills. It can also be obtained by the Future Warrior as a reward in Parallel Quest 54: "Saiyan Warriors". It is racially exclusive to members of the Saiyan race and can only be used by a Saiyan Future Warrior of either gender. In the game, it functions as an Ultimate variant of Bardock's Tyrant Lancer Super Skill. Bardock's equipable Z-Soul, I'm...only a Saiyan... greatly increases the power of this technique and increases the users stats slightly when the technique is used.
