Most games in the series come in two versions: Kabuto (lit. "Rhinoceros Beetle"), in which your starting Medabot's design is based on a Japanese rhinoceros beetle (a "KBT type" Medabot), and Kuwagata, in which it is based on a stag beetle ("KWG type"). Differences beyond the starting Medabot also exist, such as which Medabot parts the player is able to collect, and minor story differences. "Medarot R", "Medabots Infinity", and the "Parts Collection" games were only titles to not have been released in two versions.
