DescriptionEditExecuted by pressing a quarter-circle forward motion and pressing punch, Fei Long hits the enemy with a powerful punch for each input; if the full follow-up is performed, the third strike inflicts knockdown. The first input is a face-aimed jab with his leading fist; the second input is a quick gut strike with his following fist; and the final input is a backfist strike with the leading forearm.
The horizontal distance covered by each strike and recovery time in-between them are determined by the punch button pressed at the initial input, with heavier punches meaning longer reach and recovery time.The EX Special version introduced in Street Fighter IV functions exactly the same as the heavy punch version without any startup time. It also uses fiery punches and allows the very first punch to disrupt a single projectile if timed correctly.
The Rekkaken is considered the "heart" of his offensive arsenal, and is generally used as a combo finisher. Due to the pushback and distance traveled added with the range of the attack, this also acts as one of his main pokes, and as a hit confirm off of a counter hit. This trait is often given to many moves in other fighters that follow the multi-input nature of the Rekkaken, coining these moves as "Rekkas".
However, like with any "Rekka" including the Rekkaken itself, nonchalant usage of this attack during unsafe situations (depending on the move, and not too much for the Rekkaken itself in later games) can easily warrant a punish, as the recovery time of the later two inputs tends to be one of the notable weaknesses of the attack.
It can be very easy to punish past versions of the move due to the nature of it not being unlike a slide (as Fei Long moves forward while attack), thus it requires proper spacing to prevent frame disadvantage, which is especially true that unlike a slide, the hitboxes of the Rekkaken don't stick out for very long.
Each input can be delayed so that one can create frame traps if on the offense, which can make use of the opponent's temptation to punish the frame disadvantage for all sorts of openers.
The timing for the EX Rekkaken's projectile immunity is very strict, as Fei's hand must be fully out during the first punch in order to stop the projectile - but the two subsequent punches, even if timed correctly, will not nullify other incoming projectiles. Therefore, the move is thus best used at close range where Fei can capitalize on the opponent after the first hit, lowering the chances of retaliation.
- Rekkaken is the very first special special attack in the Street Fighter games (as well as one of the first in fighting games) to have multiple hits via repeatable input, classifying it as a multi-input attack. It also coins the term "Rekka" for any other similar move in other fighting games.
- Each one of the first two punches end with Fei Long performing a kiai (martial arts scream) while the last one ends in a different kiai and cooldown that plays off of Bruce Lee's notable habit of tensing himself after a blow.
