■ What is "Medarot"?
"Medarot" is a game series set in a near future where humans and robots coexist. It has gained many fans through its worldview of battling robots based on insects and animals, and its game system where players "collect", "nurture", and "exchange" robot parts and items to customize them to their liking for battles. Since the release of the first game in the series in 1997, it has solidified its popularity through a media mix expansion centered on game software, including TV anime, manga serialization in magazines, and merchandising, becoming a massive hit series with cumulative shipments exceeding 3.3 million units.
