Boomer is the evil counterpart of Rotor Walrus and a member of the Supression Squad.  He secretly aids Miles Prower, the Anti-Tails, with forcefully sending Sonic, Amy, and Scourge back to Moebius and shutting down the Globe Posts to ensure that Scourge never comes back.  However, after the Freedom Fighters debate with them about going back for Sonic and Amy, the Supression Squad reluctantly agrees and are warped back to Moebius as well, with Boomer being ready for action.  Will they come back knowing that their former leader is dead or alive?

In Sonic SATAM, Rotor has the voice of young teen, around the age of 16 or 18, filled with sentiment and compassion.  For Boomer, I would like him to sound more devious and have a slightly lower pitch, almost making him sound like he's in his 20s.
