Robin is a 16-year-old human character from *Bakugan: Mechtanium Surge*, initially part of Team Anubias and associated with the Ventus attribute. Known as the quiet member of his team, he exhibits significant strength and stamina in battle while maintaining emotional control, rarely letting feelings dictate his actions, drawing a parallel to Shun Kazami. Within Team Anubias, Robin often took a supporting role, functioning more as an observer than a frequent battler for much of the season, though his battle participation increased during critical events. He partnered with Ben to battle the Mechtogan Zenthon using Krakenoid, but was unsuccessful. He qualified for the Battle Royale using Bolcanon and Hyper Pulsor, teaming up with Soon against other brawlers; they nearly defeated Shun until Taylean created Silent Strike, leading to their loss. Robin later participated in the Capture the Flag challenge alongside Ben and Jack, battling Rafe, Paige, and Marucho with Bolcanon and BakuNano, ultimately losing to Marucho. In another match, he and Anubias faced Marucho and Shun using Bolcanon and Hyper Pulsor; Robin was defeated by Taylean, and the battle ended inconclusively due to a Chaos Bakugan invasion. A significant turning point occurred when Anubias revealed his alliance with Mag Mel. Robin reacted with horror, sadness, and depression to this betrayal. Following this, he distanced himself from Anubias and transitioned into an unofficial member of the Battle Brawlers alongside former teammates Ben and Jack. Later, Robin actively supported the Battle Brawlers against threats. He, Jack, and Ben used their Ziperators to assist Noah against Chaos Bakugan. He helped defend Dan and Drago during their confrontation with Mag Mel. During the Bakugan Interspace invasion, he battled Chaos Bakugan alongside other brawlers, escaping before the system was deleted. In the final conflicts against the Razen Titans, Robin fought alongside the Battle Brawlers, Team Anubias, Team Sellon, and Gus Grav, contributing to their victory. He joined the Brawlers in congratulating Dan at the conclusion. Robin utilized several Bakugan partners, including his primary partner Ziperator. He also employed Krakenoid in battles against Zenthon and Chaos Bakugan, and Bolcanon with Hyper Pulsor during the Battle Royale and other matches.
