Étincelles

Étincelles (Spark) is one of Elisabeth Blanctorche's Special Moves, first appearing with her in The King of Fighters XI.

Description
In The King of Fighters XI, Elisabeth thrusts her hand forward, releasing a cluster of light projectiles close to her. In KOF XII & XIII, Elisabeth slashes the air with a glowing hand.

In The King of Fighters XV, Elisabeth throws a ball of rainbow-colored light. Uniquely, the ball of light will travel a portion of the screen and stop in place, with its hitbox not becoming active until after it stops. The version has her send out two projectiles at once.

KOF XI
Étincelles is basically a short range fireball similar to the Kyokugen's Ko-Ou Ken. When used, Elisabeth will move slightly forward. The version comes out the fastest, recovers the fastest, hits 3 times and can combo from both light & strong attacks. The version comes out the slowest, but has more range, hits 5 times and can combo from strong attacks.

KOF XII
Étincelles is now turned into a short ranged attack. The entire streak of light is its hitbox, making it pretty good at controlling the space in front and slightly above Elisabeth. On hit, it causes a soft knockdown on hit, nullifies projectile based moves, builds meter on whiff, and causes a hard knockdown on a counter hit. At certain ranges, throwing Étincelles out can make it difficult for your opponent to approach Elisabeth. While it can be used to anti-air opponents, it's not her go-to anti-air move. The hit box of this move does not cover Elisabeth from the waist down, leaving her susceptible to low attacks (although interestingly enough, it can hit crouching opponents).

KOF XIII
Étincelles is now super cancelable, but not drive cancelable.

In the Arcade version of KOF XIII, this move would build quite a bit of meter on whiff. The meter gain in the console version has been significantly decreased, only building a sliver of meter now. Both the and  versions of Étincelles build exactly the same amount of meter.

KOF XV
Étincelles is now turned into a fireball; and an unconventional one at that. It's main purpose is to check an opponent when they don't want to approach. It hits multiple times, travels a set distance and is only active when it reaches its destination, and stays out even if Elisabeth is hit. This is effective against character who can hit you at midrange or zoners in general.

The version has Elisabeth throw out two projectiles, one close and a second one whose distance can be controlled by holding forward or back. Unlike the regular version, these will hit on their way forward, making it behave more like a traditional projectile. They will also knockdown if they hit, and can be useful for keeping an opponent locked in place, but the plus frames aren't enough to always justify the meter usage. There is also no way to combo from the knockdown outside of her anywhere juggle super. One big thing to note is that if used in the corner, it can go off-screen. This is no longer the case in the KOF XV Patch ver. 2.10, where not only can it not go off-screen, but it can be followed up with the normal version.
