Alien Species

Sphoeroids, also known as Sphoerodians,[1] are a pufferfish-like species from the rainy planet Scalpasc.[2]



As their species' name suggests, Sphoeroids are large blowfish/lizard-like creatures with round, fat bodies mostly dominated by their "head". They also have green skin with tan underbellies, stubby legs with rhinoceros-shaped feet, short arms with bloated four-fingered hands, and long lizard-like tails.

A Sphoeroid's face consists of a large, jaw-filled mouth with black lips, round yellow eyes at the corners, three green "quills" on the forehead, and two tan quills on the chin.

Powers and abilities[]

Sphoeroids are able to expand to spew massive amounts of a green slippery slime.

A Sphoeroid's slime can be made highly conductive by electricity, such as that generated by a Nosedeenian.

Sphoeroids possess a degree of enhanced strength, being able to push back entities around their size.

Similar to Loboans, Shpoeroids can propel themselves like rocket boosters using their slime.[3]

Because they have no nostrils, Sphoeroids are immune to poisonous gases like those on their home planet.


Sphoeroids can accidentally slip on their own slime.

Sphoeroids can be unintentionally shocked due to their slime being highly conductive.

  • The Sphoeroids were conceived by repurposing a prototype design for Upchuck's appearance in the original series.
  • The name Sphoeroid comes from "Sphoeroides", a genus of pufferfishes.
    • This species was misspelled as "Spheroid" due to trivia facts mentioned in "enhanced" versions of Ben 10 episodes that aired on the same week as the series premiere of Alien Force being lost media until 2020.
  • When attempting to incorporate Spitter into Omniverse, his design was proposed as being similar to his previous appearances but with his clothes having some green details. However, he was excluded from the series because he never came up during any episode discussions.[3]
    • During production, the crew tried to incorporate as many returning Omnitrix aliens as possible. However, they ran out of time to consider Spitter as the network believed there were too many new and returning aliens already featured in the show.[3]
    • In 2020, Derrick J. Wyatt released a full-color model of Spitter's hypothetical appearance in Omniverse.
  • It is confirmed that the Omnitrix from the Ben 10 reboot contains Sphoeroid DNA.[4] Therefore, Spitter is one of the countless aliens whose DNA pod was glimpsed in the episode "Innervasion Part 5: High Override".
    • Spitter was among the aliens considered to physically appear in the reboot but was unable to make the cut.[4]
