Tumult (騒動 Sōdō) is one of the main characters in the Rookie Chronicles. In an alternate universe, he is a Guardian Spirit to the Green Chaos Emerald, having served the Beginning since the beginning of time, until one he believed to be the Beginning sealed him away in the very Chaos Emerald he was made to protect for eons. He was later released when Shadow joined the Resistance with the Green Chaos Emerald, warning the group of the Beginning and joining Team Spectrum.
