The Longinus Knife, or Loner, is a melee weapon either carried by all four members of the Bolverk Squad or instead the Loner, the weapon's prototype.


The Longinus Knife is a highly corrosive, electromagnetic dagger which instantly numbs the victim at mininum contact.

However, Longinus Knives are more of a suicide method rather than a weapon. A simple stab with this dagger-like blade will short-circuit the cyborg and cause an explosion of large magnitude. The weapons are allegedly coded with the user's DNA, meaning that a stab with the dagger will only destroy the user or something imitating the user's genetic code.

Despite its marking as a suicide method, the Longinus/Loner has seen more use as an offensive weapon throughout the series. This weapon and Kary's Glove are the only two weapons to appear or be mentioned in some way throughout the whole series.


Xionic Madness 1Edit

Askad committed suicide using his Loner to help the squad escape XV's infected beings.

Xionic Madness 2Edit

Towards the end of their duel, Omega stabbed the alien being XV with his Loner. As the alien was linked to an imitating Omega at the time, it reacted as if it were a cyborg and promptly exploded. Somehow, Omega was able to survive, even though he was wounded, probably because he is so durable.

Xionic Madness 3Edit

At a train station, Omega and Xero encountered robotic versions of themselves that the Overseer had sent to terminate them. The four cyborgs and robots dueled with other weapons before realizing they were evenly matched. All four pulled out their Longinus knives at roughly the same time and fought with them before the cyborgs were able to stab their robotic doppelgangers. The resulting explosion destroyed half the city and the copies of themselves.

Xionic Madness 4Edit

Omega tells Xero to keep his knife close in case the fight against Kary becomes a losing one. At the end of part 3, Kary plunges her knife into her abdomen because she was about to be killed by the infected Omega, ending her own life, and halting her major malfunction.

Loner compared to Longinus Knives Edit

Xero's Longinus Knife

The main difference in these very similar weapons is the shape, and size of the weapons. The Loner's are shown to be shorter blades than the Longinus knives, and does not have a toothed edge on the back side of the blade. Where as the Longinus knives, are larger, and have the toothed edge. Longinus knives also have a few small gaps in the blade. Wether the Loner was a prototype of the Longinus knives or not is unknown.

Trivia Edit

  • The name Longinus Knife may be a reference to the Progressive Knife and Longinus Spear of the 1995 anime Neon Genesis Evangelion.
