Sandbox (Earth-1010)

Sandbox is the Omnitrix's DNA sample of an Erodinian from the planet Non Precipi in Earth-1010.

Appearance
Sandbox appears to mostly be made of sand, though underneath he as a sandstone skeleton and organic innards. He possesses a limited degree of shapeshifting, but the shape of his skeleton is consistent. He has three fingers on each hand, and three toes on each foot. His eyes are bright green, and the omnitrix symbol is located on a flexible plate of clothing on his forehead.

Powers and Abilities
Although appearing to be made only of sand, Sandbox actually possesses a solid skeleton which is in turn surrounded by sand. He can manipulate the sand as though it were his own flesh, and its solid nature allows him to even stretch his skeleton if need be. However, doing this makes his joints weaker. This skeleton makes him physically very strong and the sand makes him incredibly durable as well as giving him limited shape-shifting ability.

His sandy flesh allows him to camouflage into desserts and beaches.

Skilled Erodinians can turn their own skeletons into sand which makes it harder for them to be found in their natural environments. It is unknown if Ben ever learnt how to use this power, but Ken has not yet had enough chance to learn it.

Weaknesses
Skilled Erodinians can turn their own skeletons into sand, however doing so makes them more susceptible to their weaknesses but also makes it harder for them to be found. This can also leave their biological insides undefended.

Water makes Sandbox sluggish and unable to properly shape shift. In large amounts, it can even kill him.

The cold can also slow him down, as he fares better in warmer environments.

History
Sandbox was first unlocked by Ben Prime sometime after Death of Ben 10 but before Ken turned 10 years old. At some point before Ken receives his omnitrix on his tenth birthday, Ben shows him what Sandbox can do but Ken is not impressed. This alien was one of Ken's original set of 10, much to his disappointment.

Appearances
Sandbox has yet to actually appear.
