Omnitrix Concepts

OmniKnuckler
An Omnitrix that expands the knuckle duster design of the OV Ultimatrix into a full-on set of brass knuckles, capable of transforming with the user and unleashing modified punching attacks based on its current playlist of aliens.

KickTrix
Basically just a counterpart to the OmniKnuckler. It's a boot with soccer cleat treads. The dial is by the ankle.

Combinatrix
Basically one of those pod things from the mix and match alien parts line of toys. The gimmick would be having to assemble an alien inside the chamber before being able to use it. Different alien parts grant different powers, obviously. Each part only contains about 1/5 of the alien's full power. If this were used for a series the protagonist would basically have a bunch of mismatched parts to start with and have to search out the missing pieces in order to get access to full aliens.
