It's main goal was to penetrate Castle Bright Moon's Magical Force Dome. It's main gun was able to shoot several discs with suckers and cables attached to them. The discs would then proceed to suck the energy out of the dome, causing it to collaps. Entrapta's plan worked and the tank managed to enter the Bright Moon grounds, then shoot the energy gained from draining the force dome at She-Ra. Although the blast weakened her, the Princess of Power still managed to defeat the Trapper tank, pick it up and throw it all the way back to the Fright Zone.
