Player Swap (テレポーターのみ,Terepōtā nomi?, lit. "Teleporter only"), also referred to as Teleporter (テレポテーション,Terepotēshon?, lit. "Teleportation"), is a recurring monitor power-up in the Sonic the Hedgehog series. When used, it can swap players' positions in the multiplayer.
The Player Swap's icon on the monitors containing them varies in design, though it generally features an orange and blue arrow.
This power-up only appears in the multiplayer of the respective games it appears in. Upon breaking the Player Swap's monitor, the screen flashes white for second. When the light fades, the two playable characters in multiplayer mode will have switched places in the Zone they are currently in. In addition, any power-ups a character might be carrying (Shield, Bubble Shield, Lightning Shield, Fire Shield or Invincibility) are transferred to the opponent.
This power-up is extremely useful for the player who have fallen far behind, and disadvantageous for the leading player. However, it can still be picked up accidentally by breaking a Random monitor.
Sonic the Hedgehog 2
Player Swap first appeared in Sonic the Hedgehog 2 under the name "Teleporter" (テレポテーション,Terepotēshon?, lit. "Teleportation"). The monitors in the game that contain this power-up are marked with a yellow-framed icon that depicts a blue and orange arrow going in opposite horizontal directions.
In this game, the Teleporter power-ups are exclusive to the game's "2 Player VS" competition. Also, in the game's Options, the player may select to have only Teleporter power-ups through out the 2-Player mode.
In Sonic Mania, this power-up is referred to as "Player Swap" (テレポーターのみ,Terepōtā nomi?, lit. "Teleporter only"). The monitors in the game that contain this power-up are marked with a yellow-framed icon that depicts a blue and orange icon following each other around in a circle.
In this game, Player Swap power-ups are exclusive to the game's Competition mode. However, they only appear in this mode's Zones if the players, in the game rules, enable the "Random" feature (which produce Random power-ups throughout the mode that provide Player Swaps) or "Teleporter Only" (which replaces all monitor power-ups throughout the mode with Player Swap power-ups) before a match.
In Sonic the Hedgehog 2, the player can have Tails achieve Super Sonic's abilities during two player mode using Player Swap: First, the player must have collected all of the Chaos Emeralds and then cause the game to be over (either by losing all their lives or finishing the game). By choosing Options, the player then selects 2P from there to access 2P Mode. (Doing this will keep all of the Chaos Emeralds collected from the previous game and Sonic can transform into Super Sonic in 2P mode albeit a slightly glitched sprite). Once Sonic transforms into Super Sonic and hits a Player Swap power-up monitor, Tails will now have stars around him indicating he is invincible and he can move as fast as Super Sonic.
