Fortegreen

The Shapeshifter mainly takes the appearance of an odd-green-colored round-bodied astronaut figure with a gas tank behind their back, accompanied by a visor on their head that changes shape to express emotions in the series. The Shapeshifter, like the others, has short legs and floating hands, and because they are an impostor, they have retractable claws as well as a mouth with razor sharp teeth and a sharp-tipped tongue that they are capable of hiding and showing at will. Uniquely enough, they have the ability to manifest dark red tentacles from their body (notably their gas tank), and is capable of releasing parasites from their hands after merging with the parasite queen. While enraged or feeling murderous, the Shapeshifter is often seen with their visor, tongue, and inside mouth glowing a menacing red color.
