Roar (move)

Roar (Japanese: ほえる Roar) is a non-damaging move introduced in Generation I. It was TM05 from Generation II to as well as in , 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. Roar can hit Pokémon during the semi-invulnerable turn of .
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.
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 can no longer hit Pokémon during the semi-invulnerable turn of .
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 (due to being a sound-based move) or against a Pokémon with or rooted by . 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:
\left\lfloor \frac{X \times (Level_{target} + Level_{user})}{256} \right\rfloor + 1 \le \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.
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 and .
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 checks to always hit, unless the target is in the semi-invulnerable turn of a move (such as or ). Roar can now hit a target even if it has used , , or , but will fail if the target is protected by .
Roar can be used as part of a Contest Spectacular combination, with the user gaining extra three appeal points if any of the moves , , or 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 stat rises by one stage. cannot prevent a Pokémon from using Z-Roar.
Roar fails when used on a Dynamax or Gigantamax Pokémon.
