Overflow can create weapons out of his water, such as blades and whips, the latter of which has been demonstrated by Undertow.
He can use these to propel himself by spraying water downwards. Overflow can launch pressurized water blasts from the tanks on his forearms and his palms. Overflow has a degree of enhanced strength, being able to lift Frightwig and twirl her around. He can also withstand strong water pressure. His armor is made of Serpent Glass, which is virtually invincible. Overflow has enhanced durability thanks to an armored exoskeleton that protects his body from damage. Okay sweet, so you are like the world's most powerful watergun!
