The Michi Mk X18 "Plasma Legion" was a 10th generation unmanned tank being developed by the Sumeragi Group in collaboration with overseas company Eunos Inc.. A famously powerful war machine, even during its development period, Sumeragi has yet to produce a functional unit due to technical and bureaucratic problems.
It and an incomplete model, the Proto Legion JB, appear in Azure Striker Gunvolt 2 as weapons of the multinational Adept supremacist union Eden. During her time as a spy, Zonda stole data on the tank and provided it to members of The Seven, Teseo and Asroc, who were able to construct a unit and bring it online via their septimal powers.
The Plasma Legion is a large, bulky robot that bears 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.
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.
After being brought to Eden's headquarters, The Garden, the Plasma Legion is updated into its complete form 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 being at full power, it is eventually destroyed, and the protagonist moves on deeper into The Garden.
Proto Legion JB
|The pods on the Legions' sides open up to launch a swarm of missiles. They can be blocked by Flashfield.|
|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.|
|The device on its head springs up and produces a hexapyle-like barrier to cover its "face", erasing any tags present at the time. The barrier isn't as durable as a proper hexapyle, and is slower to regenerate when damaged. The Plasma Legion automatically deploys a ZMC Field at the start of the fight, its 2nd phase, and after completing Aero Runner.
Piercing attacks, such as most of Copen's EX Weapons, can go through the barrier.
|Fires three drill-tipped missiles, which are very durable and require a few seconds of Flashfield exposure to destroy. Upon destruction, they release energy balls which keep going.
There are two patterns:
|Plasma Cannon||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.|
|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.|
|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 reappears in Mighty Gunvolt Burst as one of the final bosses, brought forth by Teseo during the penultimate stage, Distopia, to face either Gunvolt or Beck. Like the normal Plasma Legion, only its head is vulnerable.
Characters with good aerial mobility have a natural advantage during this battle. Gunvolt's Crashbolt and Voltic Chain special skills can also deal damage from underneath.
It has a collectible pixel sticker that can be gained as a random drop from an enemy.
|The Plasma Legion fires a series of missiles from its containers, and launches a homing rocket from its head. The missiles are platforms, and must be jumped on to reach the head's height and damage it with standard shots. In Hard Mode, there are two rockets.|
|The Plasma Legion lowers its rails and fires a massive spiraling laser beam. In Hard Mode, the beam's radius is wider and there is less warning before it fires.|
|Its desperation move and a variant of Aero Runner, the Plasma Legion detaches its head, which flies off and lowers down on the opposite side of the arena. It then completely covers the floor in its jets' exhaust flames as the main body launches a stream of missiles.|

- No difference in the Korean version aside from DGレイサー being omitted from DG RASER.
- The Plasma Legion appeared in the booklet for the Armed Blue Official Soundtrack, possibly suggesting it was originally going 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.
- While Gunvolt still shouts "Oversurge! Azure Striker!", it is the only boss where his battle cry isn't directed at it.
- While not apparent at first, it is possible to go behind Plasma Legion's head, completely bypassing its shield and being free from all of its regular attacks.
- A medium boss similar to the Plasma Legion made a appearance in the announcement trailer of Azure Striker Gunvolt 3, however several modifications or upgrades have been introduced to it.
- The Plasma Legion shares its name with a boss that appears in Speed Power Gunbike, the first game developed by Inti Creates. The Gunbike Plasma Legion is capable of detaching itself, similar to the Aero Runner SP skill.
- The JP script name of Aero Runner, DG Raser, is likely a reference to the Gunbike Plasma Legion's pilots, Dan and and Gun.
