Hi, for anyone interested here is the list I made of all characters that are still a possible choice for the GB, the other characters were eliminated using the first post made by Erebus (named, still living, on Spherus Magna, not made by the GB's themselves, not mind-wiped and not a character already disproven by GregF). I also think it can't be any of the surviving Piraka because their consciousness is gone as long as they are in the fusion and it can't be the fusion because he's only been created recently and Orde stated that the GB has been observing for a long time. Finally, some Dark Hunters are highlighted in red because, if you take the rule that the character has to be named literally, they are only known by a codename.
