I roughly imagine he'll be like Chase Young from Chase Young from Xiaolin Showdown. A villain who doesn't do traditionally evil things for the sake of evil, thus is willing to work with the heroes if it benefits him.

Omi believed Chase Young had potential to return good, though this was not the case. Boom Shadow however does have the potential.

At least thats how I imagine Shadow will be like in future Sonic Boom. Heck I'll settle for the return of Lyric given hes more of a serious villain than Boom Eggman is.
