The Battle Nexus is a "nexus" of dimensions connecting many different worlds, including multiple incarnations of Earth (ex: called dimension "Third Earth" by the Gyoji) and the Triceraton homeworld. It was the home of the Battle Nexus Tournament, a competition held every three years where the mightiest warriors from numerous galaxies come together and battle to become the champion of the multiverse. The Battle Nexus was started by Lord Simultaneous and the other Time Lords.
