In this paper it is shown that any twisted KMS-functional of a C*-dynamical system is proportional to an ordinary KMS-state and the twist is weakly inner in the corresponding GNS-representation. Moreover, if the functional is invariant under the adjoint action of some asymptotically abelian family of automorphisms, then the twist is trivial. This implies that such functionals do not exist for supersymmetric C*-dynamical systems.
