Flee

Flee is a command ability in some Final Fantasy games that instructs either the entire party to run from a random encounter or a particular party member to run from that fight. It is usually associated with the Thief class. Often, using this command will cause the party to lose some Gil while running.

Final Fantasy III
One of the Thieves' abilities is Flee.

Final Fantasy IV
Edge can also employ a variant of Flee by using his Ninjutsu skill Smoke.

Porom's Cry ability flusters the enemy and makes it easier to run away in the original version, though the DS remake makes it lower defense instead.

Final Fantasy V
The Flee command is a level two ability for the Thief class.

Final Fantasy IX
Zidane Tribal can use Flee as a Skill, and it sometimes causes the party to lose Gil. The support ability Flee-Gil causes the party to gain Gil instead, though.

Final Fantasy X
Flee is located in Tidus's section of the Sphere Grid.

Final Fantasy X-2
Thieves can use the Flee ability.

Final Fantasy XI
Flee makes its appearance in Final Fantasy XI in the form of a thief job ability. This is available to all thieves starting at level 25 and can be used once every 5 minutes. Once activated, it will drastically increase the rate of speed a character can run. The player will increase in speed to about the same rate a chocobo can run in the game, but only for about 30 seconds. The run speed of Flee is just slightly faster than Chocobo Mazurka.

Final Fantasy XII
By holding down the R2 button on the controller, the active party can Flee from an area to safety. The command disables all Gambits and the party members follow the leader while ignoring any attacking enemies. It also allows you to move much faster than normal, though it isn't obvious.

Final Fantasy Tactics A2: Grimoire of the Rift
Flee is a ability exclusive to Vaan's job, the Sky Pirate.
