Summary

Terra Formars is a 2011 Japanese sci-fi manga written by Yū Sasuga and illustrated by Kenichi Tachibana. The story follows that in an attempt to colonize Mars, 21st century humanity first sought to terra form the planet by sending modified algae to change the planets atmosphere. Cockroaches were cleverly used as the method to transport the algae across the planet. Five hundred years later, the first humans descended upon Mars to see if the terra forming experiment was successful. What greeted them were giant, mutated cockroaches who possessed immense strength. The landing party was completely wiped out but not before sending a warning back to Earth. Decades later, (and with a mysterious illness sweeping Earth that may have connections to the terra forming experiment) another expedition is launched but this time, the passengers have had their DNA grafted with other bugs and animals which has bestowed them with increased strength and durability. Now, this new expedition must get to the bottom of the mysterious illness and the true catalyst behind this astounding evolution.
