Enemy Switch-Out

A special technique commonly found in anime and videogames, wherein a character has the ability to swap places with an opponent at will, potentially putting them into harms way, or at the very least, getting them out of a sticky jam. Is particularly cruel when used in the context of a race, as all of another's hard work can suddenly be taken for your own benefit.

In videogames, that is also often used to switch an enemy with another enemy, in special one which is easier to kill or will offer more problems standing on the sidelines attacking you while you are concentrated on a more important enemy. A favorite of tag team and strategy games, obviously.

Anime and Manga

 * In Hunter X Hunter, this is the basis of Goreinu's abilities. He can summon two gorillas, a black one and a white one, that are capable of independent movement; Goreinu can instantly switch locations with the black gorilla, and can force someone else to switch locations with the white one.
 * In Naruto, the substitution technique can be used as this, but is generally useless because after all most battles are one-on-one and fights happens on open fields. Kakashi however uses the technique in the Introduction Arc to switch places with a Naruto clone, making Naruto mistake his own clone for Kakashi using another jutsu, of transformation, to look like him, and causing a brawl between real Naruto and his clones as it turns out that one was not Kakashi.

Video Games

 * A staple in Sonic the Hedgehog games' multiplayer races is a Teleporter Monitor that causes the racers to switch places when opened. This Monitor was introduced in Sonic the Hedgehog 2, and has also appeared in Sonic Advance 3 and Sonic Mania.
 * Certain items and events in the Mario Party games allow you to switch spaces with other players. Some do so with one specific character (such as the Warp Pipe), while others will shuffle everybody around (such as a number of Bowser events).
 * The Legend of Zelda: Oracle of Ages has a Hookshot variant (appropriately called the Switch Hook) that acts like this, causing Link and the target to switch places.
 * Pokémon Red and Blue introduce Roar and Whirlwind, which force the opponent to switch out in a Trainer battle. This being Red and Blue, though, it only worked in the wild to end battles immediately, and wouldn't function "properly" in trainer battles until Pokémon Gold and Silver. Roar and Whirlwind also have decreased priority, allowing the opponent to potentially strike first before it hits; as of Generation III, the move will almost always go last in turn order. In competitive battling, moves like these are used to force a stat reset.
 * Pokémon Black and White introduces many variations on this. Dragon Tail and Circle Throw inflict damage and force the opponent to switch out after being hit, while the Red Card item "ejects" whoever hits the holder by forcing them to switch out.
 * Marvel vs. Capcom 2 and Marvel vs. Capcom 3 have the "Snapback" command that forces your opponent to tag out if possible.
 * Renamon in Digimon Rumble Arena has the Kohenkyo move that swaps place with their opponent. while it cannot be used in mid-air for obvious reasons, cheap players figured out they could activate it whilst on top of the trash compactor just as it was activating, potentially sending their opponent to their doom.
