Slapback is the Omnitrix's DNA sample of an Ekoplektoid from the planet Ekoplekton in the Delta Dimension of Earth-1010.


Slapback is a short green humanoid with vaguely toad-like features. His skin is a tough and metallic, and he wears blue and grey clothing covering his legs, torso, and head with black stripes and white patches. He has beady green eyes in the centre of large black eye sockets, with huge silver eyebrows. He has three fingers on each hand, and two toes on each foot. The Omnitrix symbol is located on his back.

Powers and Abilities

His main power is activated whenever sufficient force is applied to Slapback's back, as his name implies. This power causes Slapback, or any of his diminutives, to divide into two clones half the size of the original, but with twice the strength, durability, mass, and density. These clones act independently of one another and are not linked in any way. They can reform at any time, but only with another clone of the same scale as itself.

Being metallic in nature, Slapback and his clones are highly resistant to heat and fire.


Slapback cannot prevent his own duplication, any attack to his back will cause him to split. He can counteract this by refusing, however this can prove exhausting.

He cannot reach his own back to activate his duplication this way.

The individuality of his clones can cause infighting.


Slapback was unlocked when the Omnitrix reformatted after the Fulmini attempted to invade via the Omnitrix's internal mechanisms.

Ben 10: Delta Days

Slapback was used in Striking Twice. At first, he was used to investigate the mysterious crater, but he ended up being used to try and fight High Override.

He would appear again in the episode Crazy Frog where he would fight Lord Decibel, who now possesses a device capable of forcing Slapback to divide.
