Rage is when a monster has absorbed a certain amount of physical damage and reacts by becoming much more aggressive. Most monsters signal that they are entering an enraged state by roaring but the bird wyverns, like Yian Kut Ku and Gypceros, jump up and down. Even those which don't display these telltale signs still have actions that depict anger, such as red markings and/or huffs of smoke, water, electricity, fire, ice, sand or even bodily secretions (in the case of the Congalala) etc emerging from their mouths. The attack, defense and agility for each monster significantly skyrockets (to the point that some will one hit KO enemies). However, some like the Tigrex will actually experience lower increases in defense, making this a great time for heavy weapon users to attack. Monsters also develop certain tolerances (in the case of Diablos and Monoblos, they become immune to Sonic Bombs while enraged; while the Rathalos and Rathian are resistant against Flash Bombs, unless used skilfully. Likewise, the Yian Garuga will specifically avoid Pitfall Traps when enraged). It's even possible to use Pitfall Traps on an enraged Rajang or Nargacuga, who normally avoid Pitfall Traps.
The exact increases of stats depends on the monster's species. Monsters usually get enraged more often when they are close to death, some infamous examples being the Monoblos/Diablos, Khezu, Tigrex, Blangonga, Kirin, Rajang, Shogun Ceanataur, Gypceros (especially the purple subspecies) and various other subspecies, as well as creatures that demonstrate extreme aggression. Rage can also be induced by waking certain sleeping monsters (such as the Rathalos/Rathian), and in the case of Yian Kut-Ku, by stunning it with a Sonic Bomb or explosive, or occasionally by breaking a body part (a Shogun Ceanataur becomes 'locked' into rage when one or all of its claws is broken).
Most of the time, if a monster is in the middle of an attack and a hunter drives them into rage, they will stop that attack and perform the ''rage state indication''.
Some monsters, such as a Khezu, Tigrex or the Mono/Diablos, sometimes go into a state of "constant rage", in which once that monster is out of rage mode, even one single HP of damage could set it off again.
These are the increases in attack, defense and agility that some monsters experience in Rage state.
