We consider a class of little Higgs theories with T-parity where all new particles responsible for canceling the standard model contributions to the one-loop quadratic divergences in the Higgs potential are odd under T-parity, including the heavy top partner which was previously taken to be T-even. The new construction significantly simplifies the spectrum in the top sector and completely changes the phenomenology of the top partner. At hadron colliders the signals of this class of T-invariant models appear to be even more similar to supersymmetry. We initiate a study on the collider phenomenology and discuss the challenge of distinguishing this class of models from supersymmetry at the Large Hadron Collider.
