Unmei no Ya

Unmei no Ya (Arrow of Doom) is Orochi Shermie's MAX2 in The King of Fighters 2002 (as well as Unlimited Match).

Description
Orochi Shermie fires a mote of electricity to appear in the same fashion as Mugetsu no Rai'un. If it connects, a thunderstorm will materialize high above the fighters, and create a massive bolt of lightning at an apparently random point on-screen.

However, this MAX2 can backfire, causing the bolt of lightning to strike Orochi Shermie by accident and instantly K.O.ing herself. In KOF 2002, it can even hit both Orochi Shermie and the opponent, as well as completely missing either character.

Strategy
One of the worst Super Special Moves in SNK history. Its damage is poor compared to other Super Special Moves or even MAX2 Moves. Not only that, but due to the requirements of using a MAX2 (Must have 3 bars and Red Health), along with its chance of instantly K.O.ing Orochi Shermie, you have a bigger change getting the risk rather than the reward.

You are better off using literally anything else. That is, unless you're lucky, showing off, throwing a round, or when absolute victory is certain.

Trivia

 * This is so far, the only move in all of SNK's fighting game history that operates on sheer luck, or RNG.
 * Orochi Shermie's Climax Super Special Move in KOF XV makes a reference to this move; after kicking the opponent away, Shermie leaps in the air and strikes herself with lightning, before channeling it onto the opponent with her leg.
