Metal Sonic Projector

The Metal Sonic Projectors (メタルソニックプロジェクター), also called Metal Sonic Holograms, are hidden machines set around at each zone in Sonic the Hedgehog CD, possibly created by Doctor Robotnik. They are grey and dark blue colored holograms of Metal Sonic, who is showing kicking and harassing animal friends of Little Planet. Animals themselves are always different depending the zone.

Metal Sonic Projector in Sonic CD are only able to find by getting to the past of each two zones of all seven rounds. When the player finds one, Sonic has to do Spin Jump or Spin Attack into projector to destroy it. While being only optional, after doing this, animals are seen flying around freely in each timeline of the zone, especially in the good future. Unlike Eggman's machine, destroying Metal Sonic Projector doesn't give any points.
