Slapback takes the appearance of a green humanoid frog with grey metallic eyebrows and green eyes. He wears a blue, black, and white jumpsuit covering all except for his arms and feet, as well as a grey and black mask.
Slapback wears the Omnitrix symbol on his back.
Powers and Abilities
Slapback is capable of duplicating himself to an unknown degree when his back is struck. This can also be accomplished whenever Slapback applies sufficient pressure on his own back by pressing the Omnitrix symbol.
The clones are not linked in any way and can act independently from one another.
Each time he duplicates, the resulting Slapback clones become smaller and stronger by a proportionate amount. It is possible for Slapback to duplicate enough to become as dense as a black hole.[DR 1]
The Slapback clones can fuse back together into the original Slapback form.
Slapback seems unable to control his duplicating power, as each strike on his back forces him to duplicate unwillingly.
In his base form, Slapback cannot reach his own back if his arms are in a certain gesture. Therefore he is required to seek help from others when trying to activate either his duplication powers or his Omni-Kix form.
Since each of the clones have their own sense of individuality, Slapback can end up fighting himself if incensed.
If Slapback times out, the Slapback clones are automatically fuse back to the original Slapback and then time out.

From the original English name
Slapback's name is a combination of the words "slap" and "back"; this is a reference as to how his duplication powers work: by slapping his back.
A "slapback" is also a kind of doubling echo with relatively long delay between repetitions of the sound, so that the individual echoes can be perceived.
- Slapback's name was coined by Gwen and approved by Max, Phil, and a Slapback quarter when his quarters held a vote on the name.
- Ben's proposed names for the alien were "Big Boy" and "Brawno".
- Slapback replaces Grey Matter in the active playlist.
- Slapback's frog-like design resembles Bullfrag.
- Slapback's voice becomes higher pitched the more he duplicates.
- Despite being introduced in the Reboot Continuity, Slapback has been confirmed to exist in the Classic Continuity.[DR 2]
