"What do you think you're looking at?"
―Main Drain's first words to Bulk and Skull[src]

"What a power surge!"
―Main Drain's first words being enlarged[src]

Main Drain was an energy draining robot monster used by the Machine Empire. He first appears in the episode "Inner Spirit".


This monster was first enlarged by Klank and Orbus , the Rangers summoned the Zeo Megazord to battle Main Drain.  Once the Zeo Megazord formed, Tanya used the Zeo 2 Battle Helmet on the monster, but it had no effect.  The Zeo Megazord switched to its warrior mode to equip its Zeo Saber, and had managed to finally get a few attacks in as Main Drain grew visibly frustrated. Rather than try to hit them with an energy blast to regain control of the battle as would be expected, the King Mondo "begged" the Rangers to stop, as does the monster, but it was a trick as Main Drain shot his drain tubes underground and attached them to the Zeo Megazord, draining the Zeo Megazord out of its energy, allowing Main Drain to fire his lighting beams at the Zeo Megazord.  Luckily, Alpha was able to transport the Zeo Megazord out of the area.

Main Drain later returned and attacked the Red Ranger inside the Red Battlezord who got buried under an avalanche, but he later gets blasted by the Yellow, Green, Blue and Pink Rangers, he then grabs them and throws them out of the scene and blasted them with his Lighting Beams, the Red Ranger manages to regain his control over the Red Battlezord and fights Main Drain, but he lost control, for which Main Drain attacked it with his cords, but thanks to advice he remembered from Sam Trueheart, he was able to break free from Main Drain's cords and regain control of the Red Batllezord and turn the tide, after a long and heated battle, the Red Ranger was able to destroy Main Drain with the Red Battlezord.

Main Drain was cocky and overall arrogant, but he does show a lot of loyalty to the Machine Empire.

Behind the Scenes

to be added


  • Main Drain is the first monster to be faced by the Red Battlezord.
  • It's unknown why the Rangers bought into the surrender so readily as the monster was clearly winning (even with the sword they were unable to knock him down).
  • The Zeo Megazord can clearly be seen attaching the cable to itself (a "blink and you miss it" moment that can temporarily poke a hole in your willing suspension of disbelief)
  • Main Drain was the first monster to ever break a Megazord saber, which broke in two after Main Drain electrocuted the Zeo Megazord.
  • In "Fire in Your Tank," Main Drain's head was modified with horns and combined with the horns of Robogoat and the orange and blue-repainted body of Cruel Chrome.
  • It is unknown if he had any last words before his demise.
