The Protomatrix, or Prototype Omnimatrix Model IV, is the Omnimatrix used by Ben Tennyson (Dimension 666).
The Protomatrix is very similar in appearance to the Recreated Ultimatrix. However, it is a dark yellow instead of red.
Before Ben discovered Voice Command, and the ability to change its color, the Protomatrix was grey, and the dial around its symbol was a dark brown, similar to that of the Prototype Omnitrix.
Functions and CapabilitiesEdit
The Protomatrix has functions similar to most Omnimatrix models of the main timeline.
