Teleporter (Paper Mario: The Thousand-Year Door)

In the game Paper Mario: The Thousand-Year Door, the Teleporter is found in the X-Naut Fortress and leads to a secretly located room in Rogueport Sewers, which the player can use to go back to X-Naut Fortress. It was used by Sir Grodus, Lord Crump and the entire X-Naut Legion to transport themselves to Rogueport and back to their fortress on The Moon.

After defeating the Magnus Von Grapple 2.0, Mario and co. find TEC; he explains that Peach is in the Palace of Shadow, and request's Mario to save her. Mario (and one of his partners) accept; but there's no way to leave the fortress or moon; TEC, in need of talking to Mario, sacrificed all of the abandoned Fortress's electricity to activate himself. After giving his final wish and hearing Mario's words, TEC sacrificed all his energy to transfer it to the Teleporter. Mario used this to return to Rogueport.

Once Mario teleports, TEC can be heard in space. Mario's partner will ask if they heard anything (referring to TEC), though Mario will say no.
