Sandbox is the Omnitrix's DNA sample of an unknown race from an unknown planet. He is a future alien exclusive to Ben 10,000 and Ken.


The information in this section is non-canon.

Sandbox emerges from a grey box covered in green circuits, and has the Omnitrix symbol located on the front-facing side. He can contain himself entirely within the box.[TP 1]

His body is blobby and sand-like in appearance. His head has two big green eyes with a couple smaller eyes around it, and it protrudes out of a tube from the top of the box. The rest of his body emerges from multiple chutes at the bottom of the box, forming elongated arms and a slug-like lower half. Similar to Goop, his body can take on different shapes.[TP 2] His height is variable but as a standard he is approximately 6 feet tall.[TP 3]

Powers and Abilities

The information in this section is non-canon.

Sandbox has powers similar in nature to a sand blaster/sandstorm.[TP 4]

Sandbox can change the shape of his body at will.[TP 2][TP 3]

Sandbox can rematerialise into dust, and other grainy things.

Similar to Goop's Anti-Gravity Projector, Sandbox's box is a vulnerable point.[TP 5] Rather than the box holding Sandbox up, however, Sandbox instead holds the box itself up.[DJW 1]

  • Ken was greatly disappointed when he heard he had Sandbox in his Omnitrix.[1]
  • Tom Perkins designed Sandbox in 2020 from concept ideas he had during the show's run. He does not know if the writers came up with any idea what the unseen future aliens would do, as all they had at the time were the names of the aliens.[TP 6]
    • While developing Sandbox, Perkins tried to avoid depicting him like an alien take on the Sandman.[TP 7]
  • Unlike with Toepick and Atomix, the crew did not consider incorporating Sandbox into Omniverse.[MW 1][DJW 3] Had he made it into the show, he would have likely not been much different from Perkins' designs.[DJW 4]
  • There were no plans to expand on Sandbox in the reboot, but it is possible they will in the future.[DR 1]
