Remarkable, a duplicating alien.

Phil Billings.[1]

Slapback is the Omnitrix's DNA sample of an Ekoplektoid from the planet Ekoplekton.

Appearance

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.[1]

Slapback's clones get more durable the more they multiply, with Slapback quarters being durable enough to harm Bashmouth.[2]

Slapback's clones also become denser as they multiply, being able to withstand powerful winds.[2] It is possible for Slapback to duplicate enough to become as dense as a black hole.[DR 1]

Slapback is heat resistant and immune to lava. His clones are able to float on lava.[3]

Slapback is quite agile even while split into clones, as shown when his halves dodged Tetrax's crystal shard projectiles while riding some hijacked drones.[4]

The Slapback clones can fuse back together into the original Slapback form.[1]

Weaknesses

Slapback seems unable to control his duplicating powers, as each strike on his back forces him to duplicate unwillingly.[1]

There is a clear limit to Slapback's flexibility, as he cannot reach his back if his arms are in a certain gesture.[5] Therefore, he is required to seek help from others when trying to activate either his duplication powers[6] or his Omni-Kix form.[7][8]

The combined weight and mass of each set of Slapback clones may cause issues to his surroundings.[9][10] This limits how many he can reasonably make but at the same time reducing the risk of copies being harmed.

Since each of the clones have their own sense of individuality, Slapback can end up fighting himself if incensed.[1]

If Slapback times out, the Slapback clones are automatically fused back to the original Slapback.[6]

Slapback's duplicating powers can be exploited, resulting in the clones being too small to take on others bigger than him.[11]

Slapback's clones can be fused back together with enough force.[12]

Etymology

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.

Trivia

  • 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.[1]
    • Ben's proposed names for the alien were "Big Boy" and "Brawno."[1]
  • Slapback replaces Grey Matter in the active playlist.[13]
  • Slapback's frog-like design resembles Bullfrag, though Frightwig has interpreted him as a being turtle-like.[11]
  • Slapback's voice becomes higher-pitched the more he duplicates.
  • It has never been established whether or not Slapback has a limit on his duplication.
  • Despite being introduced in the Reboot Dimension, Slapback also exists in the Classic Timeline.[DR 2]
  • Slapbac's powers are similar to Echo Echo's, though the clones having individual personalities make him more in line with Ditto.
    • Their nature and execution of Slapback's powers (i.e. being able to create duplicates by applying kinetic energy anywhere on the body) are very similar to Multiple Man from Marvel Comics though while Multiple Man can use any part of his body, Slapback can only use his back.
