The Teleporter is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. They are structures that can teleport something from one place to another. They are usually found in the Hidden Palace Zone and the Sky Sanctuary.
Teleporters are presented as big, glowing, crimson marble orbs with a small ring-shaped structure around them. When using them, they emit a pink pillar of light. Supposedly, using a Teleporter is an impetuous experience.
Sonic the Hedgehog 3 & Knuckles
After stopping Walter Naugus from stealing the Master Emerald, Knuckles and Amy were surprised to find a Teleporter in Westside Island's Hidden Palace Zone, which they used to transport them and the Master Emerald to Sky Sanctuary on Angel Island. From there, they reached another Teleporter and used it to return the Emerald to its altar before the Shattered World Crisis was resolve and Angel Island would fall from the sky.
