Robot transporter

The Robot Teleporter (also known as the Roboticizer) is an object found in Sonic CD. It is placed in the past of all Rounds.

Description
The Robot Teleporter is a large machine that is about the size of Dr. Eggman in his Eggmobile. It is mostly black, but its main colour seems to be silver, the colour of both ends of its 'shell'. This 'shell' also seems to have a yellow stripe and a black and red stripe. The shells are divided by three columns of electricity. There's a dilapidated version of the machine that takes its place in the present. It looks similar to the regular one, but all the colours are replaced by shades of blue and there's no electricity going through it.

Purpose
Although its story purpose is debatable, it provides a very definite purpose in-game. Destroying just the Robot teleporters will grant the player good futures and will destroy all badniks in the zone, but it won't give the good ending. In order to do that, they must destroy the Robot Teleporters and the Metal Sonic Holograms, though the Metal Sonic Holograms don't appear in Metallic Madness.
