MachGaogamon

MachGaogamon is Gaomon's Ultimate form. Gaomon first achieves this form in episode 15 of Digimon Data Squad. In this episode, Thomas was one of the humans who had been captured by MetalPhantomon. MetalPhantomon put them under a nightmare spell; causing Thomas to relive the day of his mother's death. However, Thomas was able to break free of the spell, which awakened his DNA Charge and allowed his partner Gaomon to Digivolve into his ultimate form. In this new form, MachGaogamon was able to defeat MetalPhantomon.
