Bikkuriman 2000: Charging Card Battle is a Japanese collectible card game published by Tomy in October 1999, tied to the Bikkuriman 2000 multimedia franchise. The game interlinks two product lines: Pocket Cards (the game cards) and sticker seals from the Bug Akuma vs. Giga Tenshi seal series. When a matching seal is inserted into a Pocket Card, the card receives a stat bonus, merging the older Bikkuriman sticker-collecting tradition with structured competitive play. Each player builds a 50-card deck composed of 25 Pocket Cards and 25 Bikkuri Cards, starts with 300 hit points, and draws seven cards to begin. Victory goes to the player who reduces the opponent's hit points to zero. Characters inhabit the Bikkuri World setting and can combine their attacks into combos called Yaku. A companion video game, Bikkuriman 2000: Charging Card GB, was released for the Game Boy Color in 2000. The physical card game saw limited international distribution and is primarily documented through Japanese collector channels.
