 The Morlocks have recently joined the terrorist organization Gene Nation.In addition to mutants, Eternals, and Deviants, several other intelligent races have existed secretly on Earth.These include the Inhumans, another genetically unstable race (like the Deviants, but in their case, it is due to their use of a substance called the "Terrigen Mists") that was created by a Kree experiment long ago; the Subterraneans, a race of humanoids adapted to living below the surface, created by the Deviants (some Subterraneans were transformed into the 'Lava Men' by a demon); and "Homo mermanus", a humanoid species of water-breathers that live in Earth's oceans.
