Animal Kaiser is a trading card game released in September 2007.
Players scan their animal cards into the scanner upside down and customize their avatar by mixing and matching animal, strong and miracle cards. If they insert anything that it didn't say, example, it will say "This is not an animal card" meaning if they use a miracle card first. If they use a Japanese or Taiwan animal card into an English machine, it will say "You cannot use this card", meaning this card cannot be read by the game.
In normal mode, they fight various normal animals, such as coral snakes, rhinoceroses and more. Version 1 and 2 do not have bosses in normal mode. The Japanese version of Version 1 does not have bosses in normal mode. Instead, they fight other animals. If a boss is in a version, they can fight the boss or another strong animal.To defeat bosses,players must try to use their best animal/strong/miracle cards combination.
At the end of the game,a random card will be dispensed from the machine.
