# Terra Formars

Terra Formars (Japanese: テラフォーマーズ, Hepburn: Tera Fōmāzu) is a Japanese manga series written by Yū Sasuga [ja] and illustrated by Kenichi Tachibana [ja]. It was originally serialized in Shueisha's seinen manga magazine Miracle Jump from January to December 2011, and was transferred to Weekly Young Jump in April 2012. Its chapters have been collected in 23 tankōbon volumes as of July 2024. The story follows humanity's struggle against mutated humanoid cockroaches on Mars, leading to deadly expeditions and battles to save Earth from a mysterious virus and the invading creatures.
In North America, the manga is licensed for English release by Viz Media. A two-episode original video animation (OVA), abridging the Bugs 2 arc, was released in 2014, and an anime television series, covering the Annex 1 arc, was broadcast as well in that same year. A live action film adaptation directed by Takashi Miike was released in 2016.

## Plot

In an attempt to colonize Mars, 21st century scientists are tasked with terraforming the planet. Their goal is to seed the planet with a modified algae to absorb sunlight and purify the atmosphere, and cockroaches, whose corpses spread the algae across the planet as they feed.
Five hundred years later, the first crewed ship to Mars lands and its six crew members are attacked by giant mutated humanoid cockroaches with incredible physical strength, later labeled "Terraformars"; the crew is wiped out after sending a warning back to Earth. Two years later, BUGS II, a multinational expedition of genetically modified humans, is sent to collect 10 samples of both sexes of roaches, and exterminate the mutated bugs to take control of the red planet. Only two survivors manage to return to Earth, one swearing to return and avenge their fallen companions. As a third expedition is assembled questions are raised about the true origin of the Terraformars and their connection with an unknown disease afflicting mankind, the Alien Engine Virus, or A.E. Virus. To fight the Terraformars' strength and agility, members of the second and third expedition undergo genetic modification to inherit the characteristics of other organisms, only possible after having a special organ implanted with a 36% chance of surviving the surgery itself.
The third expedition ends with most of its crew members killed as well, be it by fighting the Terraformars, or among themselves in the multi-sided conflict between the various factions aboard the ship, each with its own opposing interests. Despite that, the few survivors manage to collect enough samples for the research on a cure to the A.E. Virus and return home. However, a new fight against the Terraformars begins when it is revealed that the creatures arrived on Earth long before. After multiplying at an alarming rate and adapting themselves far better to their new environment than they did on their homeworld, they start their plan to take over the planet.
