"Who are you?"
―Hydro Contaminator seeing Cogs[src]

The Hydro Contaminators were a group of aliens that have water pollution-motives.


The Hydro Contaminators attacked Aquitar by dumping poison into its waters. One came to Earth by following Cestro and planned to contaminate Earth's water supply. That Hydro Contaminator was destroyed by the Zeo Blaster.Tvicon.png TV STORY-Graduation Blues

The Aquitians and the Hydro Contaminators later settled their differences. Tvicon.png TV STORY-Mean Screen (episode)

Another Hydro Contaminator was seen to receive the Neo-Plutonium Armor but he was not used for battle. It's possible it's the same one that followed Cestro.Tvicon.png TV STORY-A Golden Homecoming

Behind the Scenes


  • The Hydro Contaminators are voiced by Dan Woren.


  • Apparently, the Hydro Contaminators had never heard of the Machine Empire (and possibly, the United Alliance of Evil) as the one who followed Cestro was surprised by the sudden appearance of the Cogs backing him up.
