A Soul Surge move where Sonic dashes up to his opponent and slashes them with Caliburn.
Sonic the Hedgehog's Soul Surge is a Soul Surge technique used by Sonic the Hedgehog in Sonic and the Black Knight. When using this technique, Sonic can either dashes up to his enemies and attack them with Caliburn, accelerate to top speed, or launch a powerful kick.
In order to perform Sonic's Soul Surge, Sonic's Soul Gauge must contain enough Soul Energy to initiate his Soul Surge. To activate the move in gameplay, the player must press B, and to cancel the move while being used, the player must press B. If Sonic runs out of Soul Energy, however, the move will end.
Sonic's Soul Surge can be executed in three ways; either to attack enemies, launching a kick to bump enemies or to advance quicker through the stages.
If Sonic's Soul Surge is performed as a means of heavy offense, Sonic will briefly charge up the attack, with small rings of energy emitting from his feet. Sonic will then dash up to his opponent to the full extend of his speed, appearing as a nearly instantaneous movement, and deliver a powerful slash with Caliburn to his opponent that instantly kills any lesser enemies, counters attacks or deals massive damage to tougher enemies. Once the enemy has been struck, Sonic targets the next foe and the cycle continues. This move can be used both when Sonic is in midair or when standing on the ground.
When performing this variation of the Soul Surge in gameplay, Sonic will automatically target any enemy in front of him with a red reticle. To strike the enemy, the players have to swing the Wii Remote. If Sonic strikes when the reticle is glowing bright white and Caliburn's blade is glowing, Sonic can perform a Perfect Hit for more damage and extra points.
If Sonic's Soul Surge is performed as a mean of launching a kick at opponents, Sonic will briefly charge up the attack, with small rings of energy emitting from his feet. Sonic will then jump towards his chosen opponent and strike the opponent with a fast kick with his left foot from midair, which can leave the opponent momentarily stunned.
When performing this variation of Sonic's Soul Surge in gameplay, Sonic will automatically target any enemy in front of him with a red reticle. To strike the enemy, the players have to swing the Nunchuck remote. This attack is the only way to remove Will 'o Wisps. However, it deals very little damage to enemies.
When Sonic's Soul Surge is used to give Sonic an increase in speed, Sonic will briefly charge up the move, with small rings of energy emitting from his feet. He will then accelerate to beyond his top speed in a split-second with a high-speed dash, akin to Speed Break from the Sonic and the Secret Rings. This allows Sonic to get through the stages quicker and pass through most obtacles before they can react to his presense.
When performing this variation of the Soul Surge in gameplay, there has to be no enemies in front of Sonic. To initiate the speed boost, the players have to swing the Wii Remote, and Sonic will take off at extreme speeds. While moving at these speeds, however, the players' controls becomes slightly more difficult. Also, if Sonic encounters an enemy while using his Soul Surge as a speed boost, he will automatically, switch to the attack variant of it.
- Sonic's Soul Surge is the only Soul Surge that appears in the storyline in Sonic and the Black Knight that cannot be enhanced or granted extra effects, since Sonic cannot wield any other weapons than Caliburn.
- However it is possible to gain a semi infinite use of this move by equipping a Poison Ring and using a high level Knight Style to take advantage of that styles set of skills to continuously fill the Soul Gauge.
- When done in the air, Speed Slash resembles the Homing Attack.
