Mug

Mug is an ability in various titles in the series. It is a combination of Fight and Steal, allowing the user to attack and attempt to steal an item in the same turn. Like its counterpart Steal, it is usually associated with the Thief class.

Final Fantasy V
Mug made its first appearance in this game. It was the Level 6 ability of the Thief job class.

Final Fantasy VI
Locke Cole could use this ability, translated as Capture, if he were to equip a Thief Glove. Due to a bug in the game, however, the Thief Glove replaces any "replacement effect" on Locke's weapon (such as random instant death or defense ignoring) with a Steal attempt.

Final Fantasy VII
Mug was the Level 2 ability on the Steal Materia.

Final Fantasy VIII
Mug was a non-command ability in this game, and it could be equipped when either the Guardian Forces Diablos or Bahamut were equipped. The Steal attempt would simply be made when the Attack command was used, and the command did not appear in the menu.

Final Fantasy IX
Again, Mug was a non-command ability that could only be used by Zidane Tribal. This time, if Zidane were to use his Steal command, minor damage would be done if he equipped the Mug ability.

Final Fantasy X
Mug, found in Rikku's section of the Sphere Grid, makes its triumphant return to the battle menu. This time, however, it cost 10 MP to Mug.
