  In any gauge extension of the standard model (SM) of quarks and leptons,
there is a minimal set of fermion and scalar multiplets which encompasses all
the particles and interactions of the SM. Included within this set, there may
be a suitable dark-matter candidate. If not, one may still exist from the
judicious addition of a simple fermion or scalar multiplet without any imposed
symmetry. Some new examples of such predestined dark matter are discussed.
