Master Tomo is  is a master of Ninjutsu and one of the Four Masters of legend.
Tomo was a powerful warlord who held territory in ancient Japan. His most prized possession was his over-sized shuriken. He and the other masters were lifelong enemies and failed to fulfill a prophecy to unite under a common cause in order to conquer the world. They ended up killing each other. 600 years later, Tomo's Shuriken became part of a traveling exhibit titled "Forgotten Masters". A curator from the Natural History Museum tried to set up the display on his own but he dropped the shuriken. Due to a strong attachment to the shuriken, Master Tomo manifested then he summoned Master Takeda's ghost from the Netherworld. Tomo believed the afterlife was their second chance to fulfill the prophecy that foretold the Four Masters conquering the world if they united under one cause. Takeda couldn't care less about the prophecy and was more interested in avenging his death. He attacked Tomo then noticed how they both sounded like foreigners from being around them too long. The Ghostbusters arrived and opened fire. Ray Stantz and Winston Zeddemore were unable to confine Tomo. Tomo made a new proposal. If Takeda pledged to serve him, Tomo would save him. Takeda refused and declared he would rather die again. Egon Spengler threw out a Trap. Tomo tried again and suggested serving him or spending the rest of eternity as a dishonorable dog. Despite predicting he would hate himself for saying it, Takeda pledged his sword to Tomo. Tomo attacked the Ghostbusters. He chopped Ray's Particle Thrower line, slapped Peter Venkman, stomped Winston's feet, and kicked Egon in the crotch. Tomo and Takeda fled the museum and located Master Heki's bow in Elaine Sophers' private collection then raised him. The trio trashed Sophers' house then boarded a flight to Japan to find Master Shohei. The four ghosts reunited and handily outclassed the Ghostbusters. When the Masters celebrated in unison, they were pulled together and merged into a single, powerful being named Master Prime. The Ghostbusters' used Egon's board game strategy of playing enemies against each other. It worked and they started to argue about which martial art was the best. The Four Masters split up and were trapped.
