Rustrazor Ceanataur are Deviants of Shogun Ceanataur, introduced in Monster Hunter Generations Ultimate.


Rustrazor Ceanataur looks nearly identical to a normal Shogun Ceanataur, except for its claws, with the blades at the very end having a different shape, alongside there being an additional couple curved back spikes on top. These claws are usually brown in color, though they turn an iridescent blue color once sharpened. These Ceanataur's have eclusively been seen wearing either a Glavenus and Gravios skull on their backs.


Rustrazor Ceanataur has the ability to sharpen its claws using a Glavenus's skull, allowing for its claws to become more deadly in battle, including Defense Down, it even can perform Glavenus's infamous spin by using said skull. It will also use a Gravios skull, utilizing the mouth to spray beams of "water" at opponents.


Rustrazor Ceanataur is much more aggressive than a normal Shogun Ceanataur due to its deadly claws. Due to armor not protecting hunters against this Shogun Ceanataur's attacks, it was given the secondary name, Armor Shredder. Due to this, the Hunter's Guild only allow hunters with special permits to hunt this Deviant down.

In-Game Description

Monster Hunter Generations Ultimate
MHGU-Rustrazor Ceanataur Icon.png The Rustrazor Ceanataur uses its huge pincers and the shell on its back to attack any assailants. From its Gravios shell it shoots jets of water that drill into the ground, and its Glavenus-shaped pincers can shear through steel. This two-sided nature makes it a force to be reckoned with, and earned it the name "Rustrazor". Requires special permission to hunt.
Threat Level (危険度): ★★★★★
