>>11805262 (OP)>Why is classic Sonic now considered a separate characterAround the time of Sonic Forces, Sega tried to quietly retcon Classic Sonic from being from another timeline. They've since backtracked on that.
>That was just a mistransla-The leaked script (the one where Tails calls him "Alt. Sonic") also has Tails act like he's never seen him before (which "AW" points out). So they either rewrote it that Tails recognized him, but kept the 'other dimension' stuff or somehow made a coincidentally inconvenient mistake when translating the game.
>why is he an autistic mute?Stuff like the comics still has him speaking. I can only guess that Sega doesn't really know what they want him to sound like.
