The Soul Spark (ソウルスパーク Souru Supaaku?) is one of Rose's special attacks, introduced along with her in the Street Fighter Alpha series. Menat also gain acess to the move in Street Fighter V: Arcade Edition.
Rose's Version Edit
The speed and startup of the projectile are determined by the punch button pressed: light punch version releases the slowest projectile with the least startup; heavy punch version releases the fastest projectile with the most startup; and medium punch version falls in-between. Absorbing any projectile thrown at Rose via the light punch version of Soul Reflect will increase the next Soul Spark's damage output.
The EX Special version introduced in Street Fighter IV has extremely quick startup time, travels very fast across the screen and hits twice, thus combining the best traits of every version.
Menat's Version Edit
Executed by perfoming forward, down, down-forward and pressing punch ONLY after Soul Sphere, Menat makes her orb create a small explosion, covering a considerable area. The move counts as a projectile and should it hit the opponent, launches him into the air. After the explosion, Menat's orb reappears in her hand.
This move is not recommended for projectile wars due to its input and startup lag, but it's best used to zone out opponents at a slower pace, in order to buy time to mount another strategies, and the EX version is great for keeping opponents at bay and dishing out faster damage.
