The Boomknives are the first pair of weapons employed by Xero during the escape of Xionic Madness 3.


Primary FunctionEdit

Inspired by the WWII Trench knives, the Boomknives are a pair of brass-knuckles, each containing a short, sharp dagger, perfect for close-quarters combat.

Secondary FunctionEdit

Just like Blue Shark, they have a built-in pressurized ejector for the blades, allowing them to be ejected out and fired at somebody via squeezing the knuckles hard enough. This TNT-based system is specially effective against armored targets. If the blades manage to pierce any surface, they will explode shortly after into a violent concussion shockwave. The blades are then instantly rebuilt.

Just like the Aeroblade, Boomknives can be overcharged, which enables the user to perform high-velocity slashing.

It is one of the few weapons that can be used in pairs.


Xionic Madness 3Edit

Xero used these to neutralize multiple humans and robot drones. He later used these to fight his robot counterpart.

Xionic Madness 4Edit

Xero used the Boomknives in his fight against Kary-08.
