Two copies of "Armatos Legio Centurion"
The monsters of this archetype are based on various warriors from Ancient Rome, such as the Roman Legion and Gladiators. Their design and playstyle of "forming various battle formations with their comrades" is an allusion to this. The Link Monsters of this archetype are humans in armor (with the exception of "Eques Flamma" which is a marble statue), whereas the Main Deck monsters all appear to be marble statues, wielding golden weapons and armor.
The kanji that makes up their name can be translated as "Celestial/Heavenly Cavalry". "Armatos Legio" is Latin for "Armed Legion".
Like other Cyberse archetypes, "Armatos Legio" focuses on swarming the field with lots of weak monsters in order to summon powerful Link Monsters. More specifically, they focus on "forming various battle formations with their comrades" which manifests as abilities such as the effect of "Decurion" to sacrifice itself to protect other "Armatos Legio" monsters. Their primary swarming avenues are their Field Spell, "Armatos Colosseum", and "Armatos Legio Speculata".
The Main Deck monsters, although weak on ATK, all have the ability of being able to give additional effects to "Armatos Legio" Link Monsters that point to them, which is described as "passing down their effects". This allows for solid battle formations both offensively and defensively with a wide array of effects such as being able to destroy monster instantly without Damage Calculation, making the opponent unable to attack a monster other than a specific one, being able to prevent destruction by battle or card effects once per turn, or destroy multiple face-up Monster and Spell/Trap Cards instantly.
- Ironically, considering their user's sociopathic behavior (making him the least human of the six Ignis in regards to empathy) and his extreme distaste for humanity to the point he considered enslaving and/or destroying it, the "Armatos Legio" monsters are some of the most humanoid Cyberse monsters featured in Yu-Gi-Oh! VRAINS, to the point they are even based on a human culture (the Romans).
- This irony is probably intentional, given Bohman's statement that Lightning was the most human Ignis because of his desire to survive above all else.
- The "Armatos Legio" monsters' humanoid designs make them the opposite to the archetypes used by Lightning's servants, who are all more bestial in design.
