Just hit my back and bark me through his wings.

– Omni-Kix Slapback.

Omni-Kix Slapback is the Omnitrix's Omni-Kix version of Slapback.


Omni-Kix Slapback is essentially a robotic/armored version of Slapback with a blue torso and legs, green and white arms with grey gauntlets underneath, and a helmet shaped like Slapback's head decorated with black and white detailing on the armor.

The Omnitrix symbol is located on his back connected by four tubes, with two being on his chest and the other two on his mouth.

Powers and Abilities

Omni-Kix Slapback shares the same abilities as his default form, namely his ability to duplicate when his back is struck. Each time he duplicates, the resulting Omni-Kix Slapback clones become smaller and stronger by a proportionate amount.

Each of Omni-Kix Slapback's clones are sentient and they are not linked in any way.

Each time he duplicates, the resulting Omni-Kix Slapback clones become smaller and stronger by a proportionate amount, with Omni-Kix Slapback quarters being strong enough to punch boulders that are too dense for Crystalfist.[1]

Omni-Kix Slapback's clones get more durable the more they multiply. Of course, his natural durability has increased thanks to his Omni-Kix armor. This in turn makes his smallest clones indestructible.

Omni-Kix Slapback's clones also become denser as they multiply, being able to pin down the Gladiator Bee.[2]

The Omni-Kix Slapback clones can fuse back together to the original Omni-Kix Slapback form.[3]

Omni-Kix Slapback can explode in a way that allows him to instantly duplicate.[4]


Omni-Kix Slapback shares the same weaknesses as his default form, namely his inability to control his duplication powers when his back is struck.

The combined weight and mass of each set of Omni-Kix Slapback clones can cause issues to his surroundings.

Slapback cannot reach his back to turn the Omnitrix dial sideways in his normal form to activate his Omni-Kix form. Therefore, he is required to seek help from others to activate his armor.[4][3]
