Akira (アキラ,Akira?) is Shuji's younger brother and Nene's elder brother. For most of the series he is by Shuji's side, but much later in the series, he brawls Dan and Runo alongside Shuji and Nene. The three of their attributes can be combined for the Darkus, Subterra and Ventus triple node. His Guardian Bakugan is a Subterra Centipoid. When standing next to Shuji, he was shown wearing a blue BakuPod, the trait of an Aquos battler, despite being a Subterra brawler.
