The Doom Card is an evil Ability Card from the Bakugan franchise.
The Doom Card is a Special Ability Card, appearing inBakugan Battle Brawlers. It was created by Naga for his servants. A Doom Card is set at the beginning of the Bakugan game, by Masquerade or his minions. When this card is set, any opponent's Bakugan will be sent to the Doom Dimension after being defeated.
The Doom Card is an actual Ability Card in the game. If you have a Doom Card, you can use it (except in Tournaments) and when you do, if you win the battle its used in your opponent's Bakugan goes out of the game permanently, until the game is over. It can effect the user as well. It also boosts your Darkus Bakugan's G-Power by 30 Gs.
Relations with Mechanical Bakugan
The relation with Mechanical Bakugan is a mystery, as it is not known if when the Doom Card is activated, a Mechanical Bakugan is destroyed or sent to the Doom Dimension.
Although the Doom Card is not a playable card it made a cameo appearance right before you start the battle against Masquerade in the Maximum Power tournament. It's seen while Masquerade says "Hydranoid stand!".
