The KaibaCorp space station appears in Yu-Gi-Oh! The Dark Side of Dimensions.
The station holds a highly intelligent A.I. that capable of completing the Millennium Puzzle.
The station's other facilities include a prototype system. The user sits in a pod, and the system sends the down through the space elevator in order to send them across dimensions. The station also hosts a virtual reality Duel room. Kaiba used this to Duel Virtual Dark Yugi.
Kaiba was first seen observing a virtual reconstruction of the Millennium Puzzle on the station. He later Duelled and defeated a virtual reconstruction of Atem on-board the station, but he was unsatisfied with the victory, believing it to be inferior to the real thing. After retrieving the fragments of the Millennium Puzzle, Kaiba gave the A.I. of the station the Millennium Puzzle pieces to rebuild. The A.I. was able to reconstruct the puzzle, apart from two pieces.
After his efforts to revive Atem with the Puzzle failed, Kaiba obtained Diva's Quantum Cube. Aboard the station, Kaiba spoke to Mokuba about a system. Mokuba warned Kaiba that the system was untested but Kaiba continued with it anyway. With the system connected to the Quantum Cube, Kaiba traveled down the elevator at high speed to cross into what seemed to be the underworld.
The KaibaCorp space station appears in Yugi's universe in Super INFINITY.
