Chaos Gore Magala is a rare special individual that failed to molt properly and has only molted halfway on one side. Its virus along with its attacks and strength are unstable, unlike Shagaru Magara, and its normal habits have also changed compared to Shagaru Magara like how it avoids going to the Forbidden Grounds. Its suggested by the Guild that something in the Heavenly Mountains caused it to fail molting and the Elder Dragon Observation Team even say that Chaos Gore Magala shouldn't even exist due to it catching them by surprise and shocking them the moment they saw it.

The Brachydios Variant is a Brachydios with unusual, abnormal activation of the Slime Mold without even having to lick its arms. Due to this, the Slime Mold is always active, just like the Brachydios Weapons we use and just like an enraged Brachydios, and it has also spread to all sorts of areas where the Slime Mold is confirmed to be at as well, just was never activated by its salvia.

G Crimson Fatalis(MH4G) is supposedly a Crimson Fatalis that has greatly increased in power but how and why is unknown.
