R.E.D. Kick

The R.E.D. Kick, short for Rainbow Energy Dynamite Kick, also known as 707 Shiki Komahofuri (lit. Method 707: Spin Top Slaughter) is one of Kyo Kusanagi's Special Moves in The King of Fighters series.

Description
Kyo jumps and tumble-rolls through the air, swinging his leading leg around for a slamming kick in front that hits overhead that instantly downs the opponent face-first to the ground. The version causes a ground bounce.

Strategy
This kick is a highly committal tool that Kyo can use to get around projectile zoning or pokes if he has the right read for an instantly-downing overhead on hit. Depending on the spacing and the stance in which the opponent blocks this move, the advantage can vary between punishable on block to even plus on block.

The version is one of the faster versions and leaps about 1/3 of a screen's distance. In most cases, it is generally minus or even unsafe on block and ends your turn. Can also be used in combos after a Shiki Kai for a quick and easy hard knockdown ender. Can be useful for punishing fireballs. While the version covers more distance (about 2/3 of the screen), but is slower and easier to react to. A little to safer to throw out due to always being safe on block or advantageous on block, regardless of character size or block stance, but at the same time more prone to being anti-aired or avoided on reaction. The startup makes it have absolutely no use in combos.

The version on the other hand, travels about the same distance as the  version, but at a more shallow arc and goes active a frame earlier than the  version, making it the fastest. Causes ground bounce on hit, leading itself to being a staple in Kyo's BNB combos as a way to start a juggle. This does more damage than his 75 Shiki Kai, so if you need to make a choice on where to spend half a bar, use this move. It's even more unsafe on block than the version, leaving him point-blank with punishable frame advantage, and can only go over ground fireballs, limiting its applications in neutral.
