Buddy monsters have their own set of abilities and can be used to turn the tide of the game in the player's favor. Buddyfight has a strong following among fans of anime and manga, and features a variety of colorful and engaging characters and monsters. The game has also been adapted into an anime series, further increasing its popularity. Please note that this game has been discontinued since 2020.
