Dry notes that Blue Beetle is "a High Power, all purpose Type Zero" as compared to the Anti-Knight Specialist Fear and is equipped with a higher A-Class Nohsim and multiple particle weapons. Appears in Ep0 - Ch13.
Blue Beetle is, as Dry notes, widely varied in equipment, meeting her role as a multi purpose Type Zero. Blue Beetle appears to store extra weaponry in her outer armor, which is also ablative, being discarded as it is damaged beyond repair, it turns out that all of Blue Beetles visible arms and legs are expendable.
She is first shown with the Amythyst Lance, a stabbing weapon that can project a powerful beam capable of slicing right through a Titan Class Cruiser, shields and all (Ep0 - Ch13).After Blue Beetle rescues Fear on Valtia, Dry mentions that her Voahnic Echo Shield is technology from the Central Knights. (Ep0 - Ch22)
Her primary armament is without a doubt, MJOLNIR, a large variable output, particle cannon, larger than Blue Beetle even in her Anti-Warship configuration. It is capable of warship vaporizing blasts, or razor edged cuts, all at extreme range.
She equips 4 discardable, long range, Amythyst Particle Cannons, then later draws 4 unnamed particle emission blades for close combat. Blue Beetle's baseline form is, like Fear, actually not much larger than a human. In this humanoid form she arms herself with the Violet Crystal Sword, though she can still use MJOLNIR.
Armor FormsEditBlue Beetle has four forms due to her ablative armor. The largest form is the Almighty Ultimate Weapon, The Blue. This has multiple Nohsims and various particle beam weapons. It's mainly used for carpet bombing and siege purposes.
After being simultaneously attacked by all the A-10 Dolls, she sheds The Blue and reveals the Gladiator form. This has all the Nohsims dedicated towards mobility and it's so fast that the A-10's sensors cannot keep up. The speed is so great that MJOLNIR slices multiple A-10's with little effort.
After Anne lands a Crescent Moon The Red Wave Technique, Blue Beetle sheds the damaged Gladiator and takes on her commonly seen third form. There seems to be a preference towards spear use in this form, though she does also use 4 unnamed particle emission blades for close combat.After an intense sword battle Anne lands another Crescent Moon The Red that slices right through Blue Beetle. She then sheds the damaged third form in a surprise maneuver that catches Anne off guard. A-10 saves her in the nick of time and then they start the final fight phase with Blue Beetle in her true baseline form.
