  Moir\'e superlattice systems such as transition metal dichalcogenide
heterobilayers have garnered significant recent interest due to their promising
utility as tunable solid state simulators. Recent experiments on a
WSe$_2$/WS$_2$ heterobilayer detected incompressible charge ordered states that
one can view as generalized Wigner crystals. The tunability of the hetero-TMD
Moir\'e system presents an opportunity to study the rich set of possible phases
upon melting these charge-ordered states. Here we use Monte Carlo simulations
to study these intermediate phases in between incompressible charge-ordered
states in the strong coupling limit. We find two distinct stripe solid states
to be each preceded by distinct types of nematic states. In particular, we
discover microscopic mechanisms that stabilize each of the nematic states,
whose order parameter transforms as the two-dimensional $E$ representation of
the Moir\'e lattice point group. Our results provide a testable experimental
prediction of where both types of nematic occur, and elucidate the microscopic
mechanism driving their formation.
