Leviathans are mechanical in nature. They have an humanoid frame and have the heigh and proportions of regular humans. They are clad in black metal armor and some rivets can be seen. Their helmet offers a cross-shaped visor that emits a white light when they are operative.
They are armed with dual blades on one hand and a short ranged cannon on the other.
After Omega and Xero managed to escape, Leviathans were deployed along many other forces in order to stop them. The first one are deployed inside a cafeteria-like room. Omega and Xero are able to fend off the first one by coordinating their attacks. However, as more units arrive, Omega and Xero are forced to run away because they had not got their Cervical Armor yet.
Although they are superior to regular soldiers, Leviathans are not enough to stop Omega and Xero once they both get Cervical Armor.
The Leviathans are the first step towards functional robotic infantry. They were created with the purpose of surpassing everything a flesh soldier could do on the battlefield. They have several superhuman abilities:
- Superhuman strength: Leviathans are proven to be stronger than a regular human, shattering the ground when entering combat.
- Superhuman durability: They seem completely inmune to small caliber guns. Leviathans are able to withstand several hits from the weapons of a Cervical Armor user. However, enough physical damage will finally bring them down.
- Teleportation: This ability is very similar to the Weapon Warp-In technology. Leviathan soldiers are able to materialize themselves out of thin air in a matter of seconds.
