Savage

In super, yea. But in general he's one of the strongest characters in dragon ball also. You claimed that CC goku isnt canon when technically he is canon, being canon has nothing to do with being part of main story line, considering Trunks already broke the timeline by timetraveling opening for new possibilities meaning feats such as cc goku does exist and all characters are canon if acknowledged by the author not the audience to which toriyama stated that basically anything that's in dragon ball is dragon ball, so technically goku Is the strongest dragon ball character. Just not in super but an alternate timeline of super. And don't say "it's not part of the main story bs arguement" it's dry and stale, this logic makes DC and Marvel not canon either cause they are also made by different authors but that doesnt make the characters any less of DC or Marvel or not canon does it, Same thing applies to dragon ball, goku is still goku and also I highly doubt that cc goku isnt canon cause goku black tore through reality which means it's a possibility that any version of goku exists
