Colu was the home of the Brainiac God. Preserved from the Lost Timelines, Colu was a timeline remnant that managed to stay intact after the events of Convergence. In Universe 0, there was a similar planet, called Yod-Colu, that had since been destroyed by the Multitude. The capital city of Colu was Metaire, and it was ruled over by C.O.M.P.U.T.O., a creation of Brainiac.
