I wanted to make this right after I saw the Sonic movie 2. And I guess I am the only one whose reaction to Shadow in the credit scene isn't exactly positive. Not that I hate him, but I am baffled at their choice to skip Sonic CD and even Sonic Adventure 1, just to get to Shadow. I assume that the 3rd Movie will be inspired by Sonic Adventure 2 and Shadow the Hedgehog game. Personally, I expected the 3rd movie to be mainly inspired by Sonic CD and have Amy and Metal Sonic introduced, but instead, they jumped straight to Adventure 2.

Tikal here is referring to her own game than herself (Since Adventure 1 precedes Adventure 2).
