AO

These Specials may be used to negate the effect of a Special card as it is being used to attack (i.e. avoid the attack), they may be used to remove a Special card that has already hit and become part of the "permanent record," or a Special card that is a "hit from the current Battle," they may be used to cancel the benefits, or penalties created by other Specials, and may be used to otherwise cancel, delete, negate, or otherwise void any Special card that has been played, even if the Special is not an attack Special. It cannot be used to counter a Special that your opponent played in reaction to your action. For example: Character A attacks Character B and Character B plays an "Avoid 1 attack" Special card, the player controlling Character A could not play an "AO" Special to negate the avoid. In addition, this Special can be played to negate the effect of another Special played by the opponent against any of the Character’s teammates. If used to remove a Special after the turn on which it the Special was played, then any other benefits that might have been attainted are not negated. For example, if an AE Special (combined with a Power card) hit the player's characters and the player chose not to block the attack with the AO Special, later in the Battle, if the AO Special is used to negate the AE Special, only the AE Special is removed from the hits, not the Power card that it was combined with. If a character is KO'd with a Special, this Special cannot be played afterwards to negate the effects of the KO'ing Special to bring the Character back. But, this Special could be used to negate the KO’ing Special to remove the points from the 'Hits from Current Battle', affecting the Venture total.

Meta Rules
Meta #40 Played defensively, negates cause Specials played by the opponent to be defended. Any actions described by the Special that should not be performed upon its success (discarding cards, being unable to attack, follow-up attacks, etc.) should not be performed.

Meta #41 Played offensively, negates remove any effects still being produced by a Special played by the opponent.

Meta #42 Cards which are "in play" are those cards which are: (a) on a Character's Permanent Record, (b) on a Character's Hits from Current Battle, (c) played by a Character to create some effect and has not yet been discarded.

Meta #43 Unless a Special specifically states otherwise, no Special can be played in response to an opponent's defensive action.

Meta #58 Negates are considered a card being played defensively. If a Special indicates that it cannot be defended by a Special card, then a Negate cannot be used to defend the attack (although it may be used afterwards offensively to negate the effect). If a Special card indicates that it can only be defended by a specific type of card, then this excludes all other cards (including negates).

Meta #93 Played defensively, negates defend any cards which are being used as an offensive action (and therefore defend against the rest of any attack being made).

Meta #97 If a Special that indicates it should be "played with" another card is negated, both the Special and the card it was played with are discarded. If a negate is played against a Special indicating that a card should be discarded or exchanged, then the negation takes place prior to the discarding.

Meta #128 Once a Character is K.O.'d, removing hits afterwards (either with negates, Master Mold (EE), or other legal methods) will not bring the Character back.
