Slapback

Slapback is one of the alternative alien modes employed by Ben Tennyson in the Cartoon Network animated series Ben 10. What species his genetic sample is taken from is yet to be revealed.

Description
Vaguely amphibian in appearance, Slapback is a stocky creature with a barrel chest and what appears to be natural armour or banding across his green skin. Unlike most of Ben's alien forms, he wears the symbol of the Omnitrix on his back.

Powers and Abilities
Slapback is capable of creating duplicates of himself through the use of kinetic energy, and this is where he takes his name from: the first time he duplicated, it was through a slap on the back from Gwen. However, when a duplicate is created, it is smaller in size, yet stronger, more durable and denser in mass. Each of these duplicates is capable of independent thought and action and does not appear to be linked to the others in any way. The maximum number of kinetic doubles created through this process has not been revealed.
