Bakugan Battle Brawlers - Season 4 Episode 7 BakuNano Explosion
8.30 25 minutes Dan and Drago have disappeared and all sorts of negative rumors are spreading throughout interspace. Team Anubias is dominating the battle field now that Anubias is number one in the rankings. Shun and Marucho arrive in Interspace and discover that brawlers are now using BakuNano, equipment much like Battle Gear that greatly strengthens and amplifies a Bakugan's abilities to innumerable uncontrollable power levels. When they question Dylan, they discover that the upgrade for the BakuNano just appeared out of nowhere. Sellon has another talk with Shun and suggests that he take the position of leader of the Brawlers and put an end to BakuNano use since Dan and Drago are gone. Their conversation is interrupted when Marucho is brutally defeated in battle by the Bash Brothers, two boys using BakuNanos. Shun arrives on the scene and battles the two brothers. He managed to defeat them despite not using any BakuNano himself. He speaks out to the crowd that as the new leader of the Brawlers, he will abolish the harsh and dangerous style of brawling accidently set off by Dan and Drago. Sellon is then seen stating that Shun has fallen right into her trap. The episode ends with Dan and Drago suddenly arriving at New Vestroia.
