In Emerl's story, go to Central City and go to the sonicteam building and type in these codes, 75619 for Sonic's, OTrOI for Tails', yU3Da for Knuckles', ArmIa for Shadow's, AhnVo for Rouge's, alogK for Amy's, ZAhan for Cream's, tSueT for Gamma's, and EkiTa for Chaos'. If you ask me I would say that Shadow's is the best.
