6923 Particle Ionizer


The Particle Ionizer is the third-largest M-Tron set. It is red and black, with transparent neon green parts. At the top are lasers, which could also be receivers. The ship has two fins, and on each is a thruster. The ship has three or more lasers, one in front and the rest split evenly between each side. On the back of the ship is a magnet to carry magnetic containers.

In addition to the ship is a robot and magnetic container module. The robot is about the size of a minifigure, all red and black. The container module has a magnet on top and a radio transmitter. It also has an opening lid which allows objects to be stored inside.


  • The ship comes with a small magnet crane that can be used to move around a magnetic container module stored at its aft. The middle section contains the storage space for the robot.
  • This is one of the 2 sets in which Part 2434 is red.
