That seems about right.
It's Sonic Adventure 1 and Dr. Eggman is trying to kill Sonic to take his emeralds! But oh no, what's this? A floating ball of light has brought him to the past? See what happens when Eggman visits the ancient Echidna Tribe and the Master Emerald Altar in one of Tikal's flashbacks.
Special thanks to my non-NG artist friend Dandurple Draws for the storyboards!
That seems about right.
If we ever get a Sonic Adventure remake, I want to play as Eggman where his playstyle is like Ape Escape (& Pikmin to extant) & his story is about him researching Chaos prior to the Master Emerald getting destroyed, along with fixing the game's plot-holes.
