Water rifles are the main weapons used in the Lunar League competitions and are the most common weapons.
As the name goes, water rifles can fire water projectiles at an object. They are equipped with water tanks which can fire at a semi-automatic rate. Each team has their own emblem and colours on their rifle.
- The Blood Bots' rifle is used by Bolts when he turns evil.
- The Tread Heads, Earth Command and Vinnie Two Chimes' henchmen have their own unique rifles.
- The Ion Devastator 3000 is a unique water rifle, because it was originally an actual weapon.
- There was a water rifle used by Dr. Tommy that didn't have any logo on it.
