Roar (move) - Bulbapedia, the community-driven Pokmon encyclopedia

Roar (Japanese: ほえる Roar) is a non-damaging Normal-type move introduced in Generation I. It was TM05 from Generation II to Pokémon Ultra Sun and Ultra Moon as well as in Pokémon Brilliant Diamond and Shining Pearl, and is TM172 in Generation IX.

Effect

Generation I

If Roar is successfully used in a wild Pokémon battle by either Pokémon, the battle will automatically end. In a Trainer battle, Roar has no effect. Roar has 100% accuracy and normal priority.

If the user's level is less than the target's level, there is a chance that Roar will fail, between approximately 10% and 25%, depending on the levels of the two Pokémon. The chance of failure typically increases the higher the target's level is than the user's. Specifically, the chance of failure is the following.

F a i l u r e C h a n c e = ⌊ L e v e l t a r g e t 4 ⌋ L e v e l t a r g e t + L e v e l u s e r + 1 {\displaystyle FailureChance={\frac {\left\lfloor {Level_{target} \over 4}\right\rfloor }{Level_{target}+Level_{user}+1}}}

Generation II

When in a Trainer battle, Roar will now force the target to switch with a randomly chosen Pokémon from its Trainer's party. If there is no Pokémon for the target to switch with, Roar will fail. Roar now has a priority of -1.

Roar's chance to fail does not apply to Trainer battles. However, in Trainer battles, Roar will always fail if used before the opponent has made its move. If the player uses Roar against the Red Gyarados or to try escaping from the forced wild Pokémon encounters at Team Rocket HQ, the move will always fail.

Generations III and IV

Roar now has a priority of -6.

Roar is now a sound-based move. Roar fails when used against Pokémon with Soundproof (due to being a sound-based move) or against a Pokémon with Suction Cups or rooted by Ingrain. It no longer fails if it is not used last.

The chance of failure if the user's level is less than the target's is now calculated slightly differently. Specifically, for a random integer X between 0 and 255, Roar fails if the following relation is true:

⌊ X × ( L e v e l t a r g e t + L e v e l u s e r ) 256 ⌋ + 1 ≤ ⌊ L e v e l t a r g e t 4 ⌋ {\displaystyle \left\lfloor {\frac {X\times (Level_{target}+Level_{user})}{256}}\right\rfloor +1\leq \left\lfloor {\frac {Level_{target}}{4}}\right\rfloor }

The chance of failure can be approximated by the following formula. However, this approximation may diverge moderately from the true probability for low user and target levels.

F a i l u r e C h a n c e ≈ ⌊ L e v e l t a r g e t 4 ⌋ L e v e l t a r g e t + L e v e l u s e r {\displaystyle FailureChance\approx {\frac {\left\lfloor {\frac {Level_{target}}{4}}\right\rfloor }{Level_{target}+Level_{user}}}}

Generation V

In wild Pokémon battles, Roar will now always fail if the user's level is less than the target's. In Trainer battles, Roar will now succeed if it hits, regardless of either Pokémon's level.

Roar is now reflected by Magic Coat and Magic Bounce.

If a battle with wild Pokémon ever involves more than one Pokémon on each side of the battle, Roar will fail if used by the player's Pokémon against a wild Pokémon, but if a wild Pokémon uses it against the player, it will force the target to switch with another Pokémon in the Trainer's party, regardless of the target's level.

Generation VI onwards

Roar now bypasses accuracy checks to always hit, unless the target is in the semi-invulnerable turn of a move (such as Dig or Fly). Roar can now hit a target even if it has used Protect, Detect, or Spiky Shield, but will fail if the target is protected by Crafty Shield.

Roar can be used as part of a Contest Spectacular combination, with the user gaining extra three appeal points if any of the moves Spikes, Stealth Rock, or Toxic Spikes was used in the prior turn.

If used by the player's Pokémon in an SOS Battle, Roar will fail.

If powered up by a Normalium Z into Z-Roar, the user's Defense stat rises by one stage. Throat Chop cannot prevent a Pokémon from using Z-Roar.

Roar fails when used on a Dynamax or Gigantamax Pokémon.
