AX-IV is a planet in The Transformers:Infiltrators. It is classified as a 'Type 5' planet, or a 'death world' in simpler terms. It is populated by Sandworms and a single humanoid robot. It's main interest were the massive deposits of energon that ran deep into its crust. The energon was all stable, able to be inputted directly into a Transformers circuits.
AX-IV was visited by both of the infiltration squads. After several run-ins with sandworms, Domino and Mach activated a self-destruct sequence. AX-IV eventually exploded, killing everyone on its surface.
The self-destruct sequence consists of 3 steps outlined below.
1. An EMP to disable any electrical devices in the vicinity.
2. A wave of energy that turns the stable energon into raw energon.
3. A wave of energy which starts an energon detonating chain-reaction.
After the above steps were complete, AX-IV was reduced to simple atoms floating through space.
