List of Terra Formars characters
Terraformars. The main antagonists, who hold an innate hatred for all humans, are 2m tall Martian cockroaches with humanoid bodies similar to Homo erectus, evolved by a mysterious civilization, the Rahab, who also created humanity. Their internal anatomy is nearly identical to that of regular cockroaches, and can remain mobile even when decapitated as long as the Suboesophageal ganglion remains intact and there is an open passage to the lungs. They don't feel pain and retain the abilities of normal cockroaches, such as incredible speed, strength and resistance on a human scale, allowing  them to easily defeat a normal human. There are different types of Terraformars, having adapted quickly during the BUGS 2 mission; furthermore, the Annex I mission discovered some had incorporated dead BUGS 2 crewmember capabilities, somehow copying the Bugs Procedure. Their insect ancestry is revealed by small antenna, a pair of cerci above their posterior, and the elytra covering the wings. They are animalistic, adaptable, bent on survival, and individually intelligent to different degrees. While Terraformars don't initially appear to have social structure, the Evolved Terraformars display leadership, rallying their brothers into a capable fighting force and leading their  race from their headquarters in the Martian pyramid, built by the Rahab. A love of fighting humans has caused the Evolved Terraformars to develop hot-blooded personalities who can't resist a one-on-one fight. A Terraformar leader eventually appears in the form of a roach with the appearance of a Buddhist priest who has somehow learned Kalaripayattu, but is ultimately killed by Alex in a last-ditch attack after he is badly wounded by it. A second priest-like Terraformar known as Invoker then takes its place, but this one has mannerisms more in line with a scientist  than a warrior, preferring to kidnap and study humans rather than kill them. Their intelligence is so high, they were able to rebuild the BUGS 1's old ship and fly it back to Earth, infiltrating homes in several countries; and, began learning human social knowledge through computers, cellphones and books taken from the humans killed on Earth; and, have stolen cars and clothing. They have a written motto: "WE ARE THE COSMOS". Under their new leadership, the Terraformars have revealed themselves to the public and now engage in open skirmishes with Annex 1's crew while they attempt to  kidnap humans to experiment on. They eventually take up residence on a manmade Chinese island and, following a raid by the Annex 1 crew, reveal that the experiments that they are performing are all in service of Invoker's goal of restoring the Rahab civilization.
