|Pachyrhynchus Infernalis Terraformar|
|Full name||Pachyrhynchus Infernalis Terraformar|
|Manga Debut||Chapter 37|
The Pachyrhynchus Infernalis Terraformar is a Terraformar that stole the abilities of the member of the Bugs #2's crew Jaina Eisenstein. Its enormous strength combined with the hardness of its entire body, that even the eyes are incredibly difficult to damage, makeing them both coriaceous and fearsome foes.
Unlike other BUGS surgery Terraformars, his body resembles a muscular sumo-wrestler. He wearing silk fundoshi with four "sagari". It means his social rank is lower than Silk Moth type.
Besides its natural hatred against humans shared by all Terraformars the Pachyrhynchus Infernalis Terraformar shows little to no emotion. However it seems to have an intense liking for silkworms as it munched some of them even during its fight with Marcos E. Garcia and Keiji Onizuka.
Somehow during the past this Terraformar gained the abilities of the member of the Bugs #2's crew Jaina Eisenstein.
Annex I Arc (2619 A.D.) Edit
Together with the Silk Moth Terraformar and a force of 20 to 30 regular Terraformars this Pachyrhynchus Infernalis Terraformar attacked Squad 1 on their second day on Mars killing Kaiki Kono in the process.
After initially fighting against captain Shokichi Komachi together with the Silk Moth Terraformar, it soon came face to face with Marcos E. Garcia and Keiji Onizuka who failed to do any lasting damage to it because of its hard shell. Following their attack the Pachyrhynchus Infernalis Terraformar punched the ground which caused itself, its two opponents, the Silk Worm Terraformar and captain Komachi to fall into a hole prepared beforehand.
After Marcos left to support the weaker members of the squad outside of the hole, it fought Keiji Onizuka and got killed by him despite dealing heavy damage towards its opponent.
Another Pachyrhynchus Infernalis Terraformar is seen when it emerges from the ocean alongside his fellow Terraformars near an amusement park called "Harigimi Sea Land" in Hokkaido, Japan. During their hunting trip underwater it caught a seal it is seen eating its flesh, while staring down on the park.
The Pachyrhynchus Infernalis Terraformar has the incredible hard shell typical for its base organism, as well as great strength and speed through its diet of silkworms.
