So the MHXX's site updated and revealed some new info on the Deviant Fated Four.

Hellblade Glavenus
 * Due to Hellblade Glavenus's constant tail sharpening, he has taken in extreme amounts of rich soot into his body, which has made his fire stronger and explosive. This rich soot is said to be balanced in his body, at least in theory to the Guild.

Silver Ridge Gammoth
 * Silver Ridge Gammoth's body changed due to the harsh environments she has been in for many years.
 * She is said to be able to cause blizzards and avalanches in snowy regions.
 * Her secondary name, Silver Ridge, comes from her resembling the silver peaks or ridges of a mountain.

Blue Thunder Lord Astalos
 * Blue Thunder Lord Astalos is a special individual of Astalos that's electrical body has further developed.
 * His secondary name, Blue Thunder Lord, comes from his blue-white glow when fully charged.
 * Very few have actually witnessed this monster in its fully charged state.

Heavenly Eye Mizutsune
 * Heavenly Eye Mizutsune's claws, bubblefoam, and fins have gone through their own unique development compared to other Mizutsune.
 * His secondary name, Heavenly Eye, comes from water vapor coming out of his eyes when enraged.
