If I remember correctly during the original airing...
I vaguely remember anxiously watching the new Sonic cartoon premiere that Saturday morning September 1993 on ABC and the Super Sonic episode was aired. It obviously wasn't the first episode and I was confused why Tails wasn't in the show even though he was in the opening credits. All the episode listing dates say that it aired as the fifth episode, but I distinctly remember Super Sonic being the actual first episode to premiere. I can't remember if the rest of the episodes were aired out of order, but I remember when Sonic Boom eventually aired and thinking 'now THIS should be the first episode'. Anyone else remember?
