A Rathalos (リオレウス, Liolaeus) is a type of flying wyvern from the Monster Hunter series, created by Capcom. They are one of the most well-known monsters in the series, and can appear in many varied habitats.

In Super Smash Bros. for Nintendo 3DS and Wii U

The Rathalos Armor, which is made from Rathalos' materials in the Monster Hunter series, is a DLC costume for the Mii Swordfighter.

In Super Smash Bros. Ultimate

This giant beast will appear when summoned, spreading its wings to create a powerful attack. Rathalos has fire breath and a roar that stuns opponents. Finding a opportunity to get an attack in can be difficult!

Rathalos appears as an Assist Trophy and a boss in Super Smash Bros. Ultimate’s Classic Mode and Adventure Mode: World of Light, where it serves Galeem in the latter. It possesses a stunning roar, a fireball attack, a wing attack, and it can also fly into the background and launch two explosive fireballs.

After he loses half his HP, the boss Rathalos will become faster. He can be stunned if hit by Pitfalls, Deku Nuts, or attacks that can cause stunning. Once his stamina is completely drained, the Rathalos collapses, just like in his dizzy animation.



  • Rathalos is the only character in the Super Smash Bros. series who appears as both a boss and an Assist Trophy.
  • Monster Hunter is the only universe with a Boss (Rathalos) but no Playable Character.
