Override Monster

Override Monsters (オーバーライドモンスター, Ōbāraido Monsutā,, abbreviated モンスター in since  are new monsters created by Maxus first released in Starter Deck: Akira Yurogami. There frame color are currently unknown. These cards are placed in the Main Deck.

How to Override Summon
In order to perform an Override Summon, you must first have an Override Monster in your hand. When you activate a card or card effect during either player's turn and the activated card/card effect meets the condition listed on the Override Monster, you can "Override" the activation of that card/card effect, Summon the Override Monster from your hand, then place the Overridden card underneath the Override Monster.

How Override Works
Override works by "stopping" (not negating) the activation of a card or card effect and "postponing" the effect for later. Overridden cards do not resolve and any cards/effect activated in the same chain as that are Overridden card do not resolve as well (e.g. When you activate a Spell Card and your opponent chains, if you Override the Spell Card you activated, Dark Bribe does not resolve, the card you activated it not negated, and you do not draw a card).

How "Fast" is Overriding?
In game terms, Overriding can be considered "Spell Speed 4", as it is allowed to be chained in response to Counter Trap Cards. Should you activate a Spell Speed 1 Effect and your opponent chains a Spell Speed 3 card (a Counter Trap Card), you would be able to Override the effect you activated in response to the opponent's Counter Trap Card.
