The point of this "game" is to collect the characters we like from Star Wars media.
GBA exists. GBA named Flun Flac doesn't.
Endor Rebel Captains exists. Rebel Captain Drogan doesn't, and giving him a name doesn't add anything anyone wants.
Weird robot from OR era with a serial number surely can exist. Perhaps acceptable, but borderline in my opinion.
Why add obscure fanfic toons when there are plenty of more "official" toons that more players will recognise and want to add to their collection? There are literally thousands of them just waiting to be added.
To be honest, if the toons weren't Star Wars, we wouldn't be playing. Probably a good idea not to forget that.
