– Overflow.[1]

Overflow is the Omnitrix's DNA sample of a Cascan from the planet Cascareau in the Andromeda Galaxy.


Overflow is a red metallic alien. He has two containers filled with water on his head and has black mask-like markings around his green eyes. He has two tubes of water reaching from a respirator where his mouth should be to his back, and his forearms are filled with water. He has black three-fingered hands and two black toes on each foot.

Overflow wears the Omnitrix symbol on his chest.

In The Ring Leader, he wore blue pants, a yellow cape, and green goggles.

Powers and Abilities

Okay sweet, so you are like the world's most powerful watergun!

– Overflow.[1]

Overflow has enhanced durability thanks to an armored exoskeleton that protects his body from damage. His armor is made of Serpent Glass, which is virtually invincible.[2] He can also withstand strong water pressure.[1]

Overflow has a degree of enhanced strength, being able to lift Frightwig and twirl her around.[3]

Overflow can launch pressurized water blasts from the tanks on his forearms. He can use these to propel himself by spraying water downwards.

Overflow can create weapons out of his water, such as blades[1] and whips, the latter of which has been demonstrated by Undertow.[4]

Overflow can spit water out of his respirator, as demonstrated by AntiVilgax.[5]

Overflow is able to breathe underwater and swim at high speeds. He also has amazing agility and great endurance.

Overflow can manipulate water into different states of matter.[DR 1]

Overflow has a small degree of cryokinesis, as he can create structures made of ice.[DR 1]


If Overflow shoots water at an electric device, he can be shocked while shooting, since water conducts electricity.[6]

Overflow can be harmed by magic, as shown when he was incapacitated by one of Hex's spells.[7]

Overflow can accidentally cause a flood in confined spaces if he releases too much water.[8]

  • Out of the original 10 aliens introduced in the reboot, Overflow is the only one Ben actually used for the first time while onscreen. It is implied all other aliens were first used prior to the start of the series.
  • Overflow shares some similarities with Water Hazard from the Classic Timeline, with the biggest difference being that Overflow is more robot in design with visible water tubes.
    • Cascans are actually separate entities from Orishan, with Duncan Rouleau likening the differences between the two species to those between panthers and jaguars.[DR 2]
    • Duncan is a fan of both Overflow and Water Hazard for different reasons, yet prefers Overflow for his simplicity.[DR 3]
  • Overflow is the first alien transformation to be introduced in the reboot that was not introduced in any of the classic series; this trend would continue with Gax, Shock Rock, Slapback, and Surge.
    • Despite that, Duncan has confirmed these aliens also exist in the Classic Timeline.[DR 4]
  • Overflow's voice has a slightly muffled echo, and the sound of water-bubbles popping is heard whenever he appears on-screen.
  • Despite being replaced with Rath beginning in Season 3, it was hinted by Duncan that Overflow would return in the future,[DR 5] foreshadowing his appearance in Ben Gen 10.
    • Ben could also regain access to Overflow, given how he has learned how to access the entire cache of Omnitrix aliens by cycling in new chambers from Azmuth.[DR 6][5]
    • Had Overflow appeared in Season 4, his Omni-Kix form would possibly have armor matching the suits used by other Cascans on Cascareau.[DR 7]
  • Overflow was created because the crew liked characters with water-based powers and wanted to create a new spin on an alien with those abilities.[JC 1]
