Full Counter

Full Counter is an ability possessed by the Dragon's Sin of Wrath, Meliodas.

Description
Full Counter enables its user to reflect attacks aimed at him, back at the enemy, but with much greater power; therefore, the stronger the opponent's powers are, the stronger the user's power becomes. However, two prime weaknesses are that the user cannot initiate any attacks himself, and that he would not be able to reflect attacks if the opponent does not allow him to read the nature and timing of their attacks.

Trivia

 * The ability of reflecting an opponent's attack back at him, sometimes with multiplied strength, is relatively common, and has been used in several other manga and anime series.
