"You can't stop it, Adept... Nothing can..."
Asroc , Azure Striker Gunvolt 2

The Michi Mk X18 "Plasma Legion" (ミチX一八式プラズマレギオン) is a 10th generation unmanned tank developed by the Sumeragi Group, later stolen by the Adept union Eden and a boss in Azure Striker Gunvolt 2. A famously powerful war machine, even during its developmental period, it was hijacked by Eden and used as a tool in their misanthropic schemes.


The Plasma Legion is a large, bulky robot that bares a vague resemblance to a bird. It is blue with purple highlights, stands on two short legs, and has multiple cannons and guns attached to its sides. After being upgraded, it gains a pair of horn-like rails attached to its head.


The Plasma Legion is a 10th generation unmanned tank being developed by the Sumeragi Group in collaboration with the overseas company Eunos Inc, using technology loaned by them. Despite still being in development, it shows promise of being one of Sumeragi's most powerful weapons.

As the 9th generation tank Mk 17 Mantis was called the pinnacle of unmanned tanks, development struggled to make a 10th gen tank able to overcome that reputation. The collaboration with Eunos and the usage of its loaned technology began in an attempt to undo that stagnation.

The Plasma Legion's development has suffered significant delays due to the confusion caused by the collaboration process, in addition to specifications demanded by development personnel. Nowadays, it's even said that enthusiastic developers who suggested "Let's add a detachable body function" contributed to the confusion. The delays are such that Sumeragi is still not known to have a functional unit as of the events of ASG2, despite its fellow 10th gen tank Spyder developed in parallel having combat-ready prototypes as of the events of ASG1.

Azure Striker Gunvolt 2Edit


During Zonda's infiltration of Sumeragi, she acquired the tank's design data and gave it to Teseo. Teseo used his septima "Hack the Planet" to recreate the tank, but did so in a rush. The resulting prototype is known as the Proto Legion JB, and lacks many of its fully developed version's features. Teseo uses the robot to attack Gunvolt to prevent him from reaching the Seraph's control room. Gunvolt swiftly defeats the machine, but it is seemingly teleported out by Teseo before he can destroy it.

The Garden 2 (Inferno)Edit

After being brought to Eden's headquarters, The Garden, the Plasma Legion is updated into a far superior machine by Teseo and Asroc. Depending on if the player is playing as Gunvolt or Copen, the Plasma Legion will be summoned by either Teseo or Asroc, using the last of their power to order it to destroy the intruder. However, despite the Plasma Legion's impressive new upgrades, it is eventually destroyed, and the protagonist moves on deeper into The Garden.

Other AppearancesEdit

Mighty Gunvolt BurstEdit

The Plasma Legion reappears in Mighty Gunvolt Burst as one of the final bosses, brought forth by Teseo during the last stage to face either Gunvolt or Beck.

It has a collectable pixel sticker that can be gained as a random drop from an enemy.


First fightEdit

Hummer DEdit

The pods on the Legions' sides open up to launch a swarm of missiles. They can be blocked by Flashfield.

Plasma BallEdit

The Plasma Legion charges its cannon to fire a large green plasma ball at you. If the projectile hits the ground, it splits into two smaller balls that travel along the ground. The Plasma Legion will always fire 3 shots with this attack.


The Plasma Legion is being manipulated by Teseo's septima "Hack the Planet", so he can essentially copy-paste it onto the other side of the arena. It will perform this move once per phase.

Second fightEdit

ZMC FieldEdit

A shield generator pops up from the head, creating a Hexapyle-like shield to protect it. This shield blocks tags, but can be bypassed with piercing attacks.

Stabilizer: ForwardEdit

The Plasma Legion fires three drill missiles forward. These missiles are extremely durable, requiring a few seconds of Flashfield exposure to destroy, and launch green energy balls upon their destruction.

Stabilizer: RainEdit

Fires three drill missiles into the air that descend and bore into the ground before detonating. These missiles are extremely durable, requiring a few seconds of Flashfield exposure to destroy, and launch green energy balls upon their destruction.

Plasma BallEdit

The Plasma Legion charges the cannon inside its mouth to shoot a blue energy ball. If it impacts the ground, it splits into four smaller balls that travel along the ground. The Plasma Legion will always fire 3 shots with this attack.

Legion TornadoEdit

Rails flip down from the shoulders before it fires a massive blast diagonally downwards. The only safe spots are right near the Plasma Legion or in the air.

Aero RunnerEdit

The Plasma Legion's special skill. It detaches its upper and lower halves, the upper half staying afloat via jets. The upper half flies above in a plasma field while the lower half drives along the ground. They run along the upper and lower halves of the screen, leaving only a small row along the center safe. After three runs with this move, the unit reforms at the opposite end from where it started.


  • The Plasma Legion is the first robot to serve as a boss in the series.
  • The Plasma Legion appeared in the booklet for the Armed Blue Official Soundtrack, possibly suggesting it was to appear in the first game.
  • The Eunos Inc. mentioned in the Plasma Legion's profile in the Armed Blue Official Soundtrack booklet is likely named after Eunos, a type of car once made by Mazda.
