The Parasite resembles a mix of a humanoid with a Reptile-like creature. Its skull has been melded to its chest and it has Lizard-like rear legs. The new "head" is an exposed brain with skin flaps on both sides. It has human arms. The ribs have mutated and grown longer/point outward and are used to grab you from behind. From the pelvis bone, small clawy hind legs have sprouted. The Parasite has one big tentacle that it uses to catch you. He wants to become one with you
