  Universal vector wave equations allowing for a unified description of anyons,
and also of usual bosons and fermions in the plane are proposed. The existence
of two essentially different types of anyons, based on unitary and also on
non-unitary infinite-dimensional half-bounded representations of the (2+1)D
Lorentz algebra is revealed. Those associated with non-unitary representations
interpolate between bosons and fermions. The extended formulation of the theory
includes the previously known Jackiw-Nair (JN) and Majorana-Dirac (MD)
descriptions of anyons as particular cases, and allows us to compose bosons and
fermions from entangled anyons. The theory admits a simple supersymmetric
generalization, in which the JN and MD systems are unified in N=1 and N=2
supermultiplets. Two different non-relativistic limits of the theory are
investigated. The usual one generalizes Levy-Leblond's spin 1/2 theory to
arbitrary spin, as well as to anyons. The second, "Jackiw-Nair" limit (that
corresponds to Inonu-Wigner contraction with both anyon spin and light velocity
going to infinity), is generalized to boson/fermion fields and interpolating
anyons. The resulting exotic Galilei symmetry is studied in both the
non-supersymmetric and the supersymmetric cases.
