|This article is about a/an Venjix Attack Bot in Power Rangers RPM.|
Venjix created this Generation 9 Amphibious Attack Bot, and ordered him to infiltrate the city's water supply, via the hydraulic circulatory system. The bot did manage to enter Corinth, and he released the Shield Disruption Mist, that allowed the Grinders to enter the city.
The Rangers quickly showed up and battled the Grinders. After the robot soldiers were out of the way, the Rangers were able to battle Water Hoser with their weapons. Though they were more than a match for him, the monster was able to turn back into water and escape through the city's main water line.
Water Hoser re-emerged in the harbor, only in his giant size form. The Rangers were kept at bay by a large army of Grinders. Once Ranger Black showed up, the others were able to summon their Zords and form the High Octane Megazord. In the battle with Water Hoser, the Megazord was sent crashing into a city bridge. This made it to where the Megazord had to hold the bridge steady, so that the people still on the bridge could get to safety. But Water Hoser took advantage of this attacked the Megazord.
Once everyone was safe, the Rangers were able to fight with the High Octane Megazord again. They then managed to trap Water Hoser in the bridge, and used the Super Saber attack to destroy him. (RPM: Rain)
