Ultraman 80

Alien Bam created a train capable of traversing the barrier between the 3rd and 4th Dimensions, luring unknowing humans on to it. In the 4th Dimension, they were mind controlled and used as slaves to help in the creation of Mechagiras, a robot with the ability to travel between the 3rd and 4th Dimensions with ease. With Mechagiras's completion, they could put into motion their vile plot.

The first step of their plan was capturing Takeshi Yamato, the human form of Ultraman 80 and current defender of Earth to ensure he could not interfere with their plans. It was successful, having brought him into the 4th Dimension on an inter-dimensional train.

Powers and Weapons
  • Inter-Dimensional Train: Through the use of unknown technology, the Alien Bam created a train capable of traversing between the 3rd and 4th Dimensions and used it to transport human slaves. Its presence is seemingly signaled by the bending of space and time as the night sky distorted when it appeared.
  • Batons: Most Alien Bam were armed with batons.
  • Power: The Alien Bam are said to have "the power of 50 green berets". Despite this, Takeshi Yamato was still able to seamlessly take out entire groups of them.
  • Dimension Core: In their base, the Alien Bam had a core-like device capable of altering the 4th Dimension to their will, mind-controlling humans and preventing the transformation devices of ultras from working.
  • Human Disguise: Alien Bam can alter their appearances to be that of humans, using it to lull Takeshi into a false sense of security.
  • The 4th Dimension: The home dimension of the Alien Bam, no matter where one goes, they would eventually wind back in the same place they started from. Devices such as watches are also useless while in the 4th Dimension.
