I think it does scream Sonic. We may be more used to kaijus in Modern Sonic games, but for me whatever fits Sonic, fits Sonic, whenever it's Classic or Modern. I agree that it's random. Spoiler We were tempted with the concept of "Eggman roboticizes giant legendary animals" but it goes nowhere. All we got were just regular boss superbadniks that simply contained giant pigs, birds and seals in them. We meet giant snake and yeti, but they end up as decorations instead of bosses. Reversing time to resurrect a dragon to roboticize might have worked, but the game never makes an explicit connection between time reversal and dragon. And it's never roboticized, it turns out that the dragon is evil all along even without Eggman's involvement and Trip turning into a dragon ends up as just a joke. And for whatever reason my brain interpreted this song as Number One from Bleach and I still have that song in my head because of that.
