The combo itself is simply as follows: single jump f-air, midair jump d-air. However, some players refer to the entire chain of n-airs and f-airs followed by the spike as a "Ken combo" due to its effectiveness in SSBM competitive play. However, it should be noted that players can usually escape this combo by DIing the f-air out. According to Ken himself, the Ken Combo was initially discovered and developed in the original Super Smash Bros. using Captain Falcon's spike.
