One day in a small mining town, an earthquake had occurred without warning. All of the miners except one escaped so he could save his pet mouse and as he did he saw two lights glowing from the darkness. The Ultra Guard was called in to investigate the situation as well as rescue the miner. When investigating Dan found out that the miner was the man who he took the appearance of. Seeing no alternative in the cave the Ultra Guard called in a giant mobile drill called the TDF MRI to help them dig through the cave in. As the miner started to go blind, the Ultra Guard found very large tunnels not long after the TDF MRI was sent in. Just then another miner came out of the mine screaming about a monster in the mine, making the Ultra Guard speed up their rescue mission in case what he said was true. The TDF MRI was forced to stop because their laser encountered a rock that was extremely tough. Before they could break it another earthquake happened when a large metal door closed down behind them, trapping them in place. After communications failed Dan volunteered to place several small bombs along the hard rock. After the explosions Dan disappeared, but the rock was gone and revealed a hidden underground base of an ancient technologically advanced society. Just then the robot guard, an U-Tom, showed up and shot at the Ultra Guard until it's eye was hit and was deactivated. However, more U-Toms were around the base patrolling it. At the same time Dan found himself on a table with high gravity and the Ultra Eye on a table with his gloves and helmet. Dan activated a device on his belt that levitated the Ultra Eye to him and allowed him to turn into Ultraseven. After dispatching a U-Tom with the Wide Shot Ultraseven found the miner unconscious and brought him back to the TDF MRI with the Ultra Guard setting the rest of their bombs all over the base. The base of U-Toms was destroyed and the Ultra Guard escaped with the miner.


  • The U-Toms' appearance is based off Robby the Robot from the 1956 film, Forbidden Planet.
    • In an interview, Tetsu Yamamura stated that the U-Toms were meant to be essentially mechanized M1s from Ultra Q.
  • Only one suit was made for the U-Toms, three chest plates were made to differentiate them from one another.
  • U-Tom was never referred to by name for years, leading some to believe that hey were simply modified versions of another Ultraseven robot, King Joe.
  • Suit Actor: Haruo Nakajima.
  • Although not physically seen, U-Tom is one of the monsters that make up Beryudora's Left Arm in Mega Monster Battle: Ultra Galaxy Legend The Movie.

Powers and WeaponsEdit

  • Magma Gun: U-Toms have a gun for their right arm that can shoot energy bullets, although these are weak as they are easily reflected off on tougher substances.
  • Hammer Hand: U-Tom's left hand were durable and can be used in a manner of a hammer


  • U-Toms will be deactivated if a powerful enough attack hits their eye.
