Unlike its predeccesor, CoffinBat, its arms (except in Medarot DS) and head shoots anti-air missiles. It has no arms and its hands are on its legs part, making its arms a kind of missile carriers. Aside that Goughbullet is a rather weak Medarot, but wisely used, it can be a threatening anti-air force.
In the games
In Medarot DS
Its series number is now BAT01-M. Its head is renamed Echolocate (エコロケ), and instead of Anti-Air, now uses Stealth.
In the anime
Hundreds of Noctobats serve as foot soldiers for the Rubberobo Gang.
In "Ban All Medabots," the Rubberobo Gang used the Noctobats to attack Ikki Tenryou's school. The students used their Medabots to fight the Noctobats where the fight reminded an elderly teacher about the war. While some Noctobats were taken down, some of them defeated Cyandog and Totalizer. Rokusho arrived and broke up the fight where he suggested that representatives on each side should battle it out which led to Ikki's Metabee and the Principal's Samurai fighting against the Rubberobo Gang's two Landmotors.
