Hyrule Jump
The Hyrule Jump refers to the act of crossing the open space from Temple's upper right ledge to its bottom-most platform. Every character can perform the Hyrule Jump, though it is considerably difficult for characters with short recoveries, in particular Falco and Roy. Since Temple is banned in the standard tournament ruleset, the Hyrule Jump is never seen in competitive gameplay. However, in single-player-mode matches, the Hyrule Jump may be useful in disorienting CPU opponents because they must travel a long distance to get to the player's new position. Another term for this is "Temple Crossing"
Reverse Hyrule Jump
The Reverse Hyrule Jump is the act of performing the Hyrule Jump in reverse, or jumping from the bottom-most platform to the right-most ledge. Sonic, Jigglypuff, Luigi, Wario, Kirby, Pit, Meta Knight, R.O.B., and Mewtwo are known to be able to do the Reverse Hyrule Jump. Link, Peach, Snake and Young Link are technically able to perform the Reverse Hyrule Jump as well, by using their down B bombs to damage themselves to the point where the bomb's knockback can carry them most of the way to the upper ledge. Like the Hyrule Jump, this is more of a show-off technique for fun than a true gameplay maneuver, though in single-player-mode matches it may help in disorienting CPU opponents because they must travel a long distance to get back to your new position.
Wario, Jigglypuff, Kirby, Sonic, and Meta Knight are the only characters who can do the Reverse Hyrule Jump without using their Up-B attacks.
