Metalfencer is a Trap Bakugan that enhances Viper Helios's fighting skills. His three blue eyes can freeze opponents, making them easy to defeat. Not only can his long tail shoot lasers, it can also wrap and squeeze his opponents tightly, eliminating them with its deadly stinger. His four mighty legs provide tremendous maneuverability.
It was used by Spectra in Show Me the Power! where it combined with Viper Helios to form battle unit mode. It was knocked off of Viper Helios by Neo Dragonoid, but it was not defeated, however, Helios asked Spectra for more power and Spectra used the Forbidden Card to win that battle.
It was used again in Dude, Where's My Bakugan? to save Viper Helios from Apollonir's Saiam Low ability by combining to make Battle Unit Mode, however Apollonir still managed to beat Viper Helios and Metalfencer.
