The IDSC is a crime syndicate that spans several omniverses and even is rumored to have access to the Beyond.

The IDSC or the Inter Dimensional Crime Syndicate, is run by Sigma, Omega's right hand man and one of the Inner Circle members of the UDR.

The IDSC basically is a secret backup transportation network that also deals with crimes in other worlds.

The IDSC is responsible for destroying several planets and universes by selling superweapons or biological, or even universe buster artifacts that we have gave to the IDSC.

The IDSC is the official other end of the Dimensional Enforcement Department or DED.
