The Underground is a group that appears in the Sonic the Comic series published by Fleetway Editions. They were a secret society consisting of the last living beings on Planet Metallix led by Dr. Ovi Kintobor in the timeline created by the Brotherhood of Metallix.
In the timeline created by the Brotherhood of Metallix when they rewrote Mobius' history, the Underground was formed from the last living creatures on the planet when the Brotherhood of Metallix seized control of Mobius and renamed it Planet Metallix. Being hunted by the Brotherhood, the Underground were forced live beneath planet's the surface in hiding, with their leader Dr. Ovi Kintobor helping save any Mobians in danger.
Return of the Chaotix
In 1996, Kintobor and his associate Rob rescued Sonic the Hedgehog, Porker and the Chaotix Crew (who had not been affected by the Brotherhood's change in history) from a squad of Metallix. After Kinotobor showed them the Underground's base, Kintobor and Sonic explained the situations both parties was in, leading to the formulation of a plan to go back in time and prevent the birth of Planet Metallix. To aid Sonic, Kintobor gave him the Anti-Metallix Device.
After Sonic successfully restored history, the Underground would cease to exist in the present.
