Rathalosリオレウス
Flying Wyvern ・ 火竜

A wyvern feared as the King of the Skies. Together with the Rathian it keeps a wide territory around its nest and watches it from the air. It dives down on intruders with its fine flying skills and attacks with strong, poisoned talons. It breathes fire, which is why it is called the "fire wyvern."
The flying wyvern called the King of the Skies. A strong flier, it dives from above and strikes prey with its talons.

King of the Skies天駆ける王者
Rathalos, King of the Skies. Alongside the female Rathian, it stands for all Flying Wyverns. A strike of its poisonous talons from above is too much even for large monsters.

Movie notes from the gallery in the game
How the guidebook says to hunt it
A male wyvern skilled at attacks from the air
Its fire breath causes fireblight, and its kick from above causes poison. Bring cures such as Nulberries and Antidotes. When it appears together with Rathian, it enrages easily when she is blinded, stunned, knocked down, has her tail cut, falls into a Pitfall Trap, or gives an enraged roar near death, and it tends to come and join her.

Tips
- Thunder and dragon work well
- It has strong wind pressure
- It has a quiet roar
- When Rathian is also there, each one comes to the other's aid when it is in trouble

Brackets after the damage give its element or status. Damage is the health the hunter loses. Guard break is how hard the attack pushes through a guard, and stun is how much it builds toward stunning the hunter. Stamina use is what the attack costs the monster. The levels are Low, Mid, and High; - means none.

Intruder rewards
In an intruder quest a new monster turns up after the quest's clear conditions are met. Clearing the quest after that gives these rewards. Intruders only come in Gathering Hall high rank quests.
| Reward | Chance |
|---|---|

| Rathalos Scale+ x2 | ★★ |
| Rathalos Plate | ★★ |
| Inferno Sac x2 | ★★ |
| Rathalos Medulla | ★★ |
| Rathalos Wing x2 | ★★ |
| Rathalos Ruby | ★ |
More stars means the reward is easier to get. To skip an intruder, pick Return to Village from the menu once it appears: the quest clears at once and gives the normal quest rewards.
