Tenmakujinkyaku

The Tenmakujinkyaku  ( 天魔空刃脚, "Demon Sky Blade Leg")  is one of Akuma, Evil Ryu, and Gouken's Unique Attacks. Seth also copied this move, with a different input.

Description
Akuma jumps, landing with a strong kick that inflicts high damage; if successful, Akuma can follow up with any other attack, making this a good combo starter. It is very similar to his Hyakki Gojin, but is somewhat easier to perform.

This attack can beat out a Shoryuken if both are executed at the same time, but it cannot cancel Sakura's Shououken and Dan's Koryuken.

In the Marvel vs. Capcom series, the attack's input was changed to a quarter-circle forward motion. Implying that it is converted as a special attack.

Trivia

 * In the Special Edition of Devil May Cry 3, Vergil possesses his own version of the Tenmakujinkyaku, called Starfall. The Level 2 of this move sees his legs glowing brightly, referencing its name.
 * Magma Dragoon, one of the bosses in Mega Man X4, possesses a fire-elemental version of this move, dubbed as the Enkoukyaku ("Flame Descending Leg"). This move also returns in Mega Man X8 as one of the special attacks Zero can use when equipping the K-Knuckle.
