----
In the main series Pokémon games, it is possible to '''escape''' from a {{pkmn|battle}} with a [[wild Pokémon]] by selecting "Run" on the main battle screen.  Escape is not guaranteed however; whether the player is successful at running away from the battle is determined by a calculation involving the speed of the combatants.  When the escape is successful, the battle ends immediately. When it is not successful, the wild Pokémon will attack the player's Pokémon.

It is not possible to escape from in-game {{pkmn|Trainer}} battles.  However, in player battles in the Cable or Wireless Clubs, attempting to escape will cause the battle to end immediately.  If only one player attempts to escape, the battle counts as a loss against them, but if both players attempt to escape in the same turn, the battle ends in a draw.

Entering a battle with a wild Pokémon and then escaping counts the Pokémon as being seen in the Trainer's [[Pokédex]].

==Success conditions==

Under normal circumstances, the chance of escaping is determined by the formula [[Image:Escape Formula.png]], where 
:A is the current {{Stat|Speed}} of the player's active Pokémon,
:B is the opposing Pokémon's Speed divided by <tt>4</tt>, <tt>mod 256</tt>, and
:C is the number of times the player has tried to escape during the battle (counting the current attempt).
If F is greater than 255, the player escapes automatically. Otherwise, a random number is generated between 0 and 255. If that number is less than F, the player escapes. If not, the escape fails and the player's Pokémon does not make a move that turn.

Several other conditions can cause escape to always succeed or always fail.
* An opponent Pokémon with the Ability {{a|Shadow Tag}} causes the player's escape attempts to fail if the player's Pokémon does not also have Shadow Tag.
* An opponent Pokémon with the Ability {{a|Arena Trap}} causes the player's escape attempts to fail if the player's Pokémon is not {{t|Flying}} type or {{a|Levitate|levitating}}.
* The reusable held item [[Smoke Ball]] causes its holder's escape attempts from wild Pokémon to succeed.
* The items {{DL|Escape item|Poké Doll|Poké Doll}}, {{DL|Escape item|Fluffy Tail|Fluffy Tail}}, and {{DL|Escape item|Poké Toy|Poké Toy}} can be used to escape from wild Pokémon.
* [[Trapper|Trapping move]]s used by the opponent can prevent the player from even making escape attempts.
* If the player's Pokémon is under the effect of {{m|Ingrain}}, it will be unable to escape.
* The Ability {{a|Run Away}} causes escape attempts to succeed and ignores anything above that would prevent escape. This applies even if the user of Run Away has fainted.

While not effects that directly affect escape, using the moves {{m|Whirlwind}} or {{m|Roar}} in a wild battle forces the wild Pokémon to leave the battle, which has the same effect as escaping. However, if the wild Pokémon has the Ability {{a|Suction Cups}} or has used the move {{m|Ingrain}} previously in the battle, it will be immune to Whirlwind and Roar. Similarly, a Pokémon that has the Ability {{a|Soundproof}} is immune to Roar.

===Example===
The player's Pokémon has a Speed of 25 and the wild Pokémon has a Speed of 100. The player tries to escape, but hasn't attempted to flee anytime earlier in the battle.

First, calculate B: [[Image:Escape Formula Example 1.png]]

Since B isn't above 255, it is just left as is.

Then, calculate F: [[Image:Escape Formula Example 2.png]]

Since F isn't above 255, generate a random number between 0 and 255.

The probability of escaping is [[Image:Escape Formula Example 3.png]], or approximately 24%. If the player fails to escape, each successive attempt will be 30/256 more likely than the last, or about 11.7%.

==Wild Pokémon==

Certain wild Pokémon can escape from battle. Pokémon that are [[Legendary Pokémon|legendary]] or found in the region's [[Safari Zone]] are the only ones who flee.

[[Roaming Pokémon]] attempt to flee every turn, and trapping moves can be used to prevent this.

In the [[Safari Zone]]-type areas, Pokémon that are encountered will escape from battle if "angered". In all of these games, the rate of escape is lowered by throwing Bait{{sup/1|RBY}}{{sup/3|FRLG}}{{sup/4|DPPt}}{{sup/4|HGSS}} or [[Pokéblock]]s{{sup/3|RSE}} (while the [[catch rate]] is also lowered), and the rate of escape is raised by throwing Rocks{{sup/1|RBY}}{{sup/3|FRLG}}, Mud{{sup/4|DPPt}}{{sup/4|HGSS}}, or by "going near"{{sup/3|RSE}} (while the catch rate is also raised).

In {{3v|Gold|Silver|Crystal}}, only a few species of wild Pokémon can escape from battle.

Low probability:
* {{p|Magnemite}}
* {{p|Grimer}}
* {{p|Tangela}}
* {{p|Mr. Mime}}
* {{p|Eevee}}
* {{p|Porygon}}
* {{p|Dratini}}
* {{p|Dragonair}}
* {{p|Togetic}}
* {{p|Umbreon}}
* {{p|Unown}}
* {{p|Snubbull}}
* {{p|Heracross}}

Medium probability:
* {{p|Cubone}}
* {{p|Articuno}}
* {{p|Zapdos}}
* {{p|Moltres}}
* {{p|Quagsire}}
* {{p|Delibird}}
* {{p|Phanpy}}
* {{p|Teddiursa}}

Always:
* {{p|Raikou}}
* {{p|Entei}}
* {{p|Suicune}} (except in {{v|Crystal}})
