Gooey or Bandanna Dee - I think Bandanna Dee is more likely since Kind Dedede throws Gordos now.

Isaac - He simply disappeared in the game and is not even avaiable in the 3DS version, considering Golden Sun had only handheld games. He may appear as DLC.

Impa - Since she appeared in many Zelda games, I think she can be DLC in some way.

Mah Rider (FROM MACH RIDER, not Excitebike) - In my opinion, he has a chane to be DLC, but that's very unlikely.

A Removed character - Lucas, Wolf and Ice Climbers seems more likley, but the Ice Climbers may be Wii U exclusive DLC.

Rayman - He's VEEERY unlikely to appear as DLC.
