Even if it was, say, a ALIENS crossover, even with Sonic's speed against the xenomorph, depending on what spaceship he's on may not be as glamorous if he;s cornered.
Xenomorph would be more perfect opponent for Tails. Playing hide and seek, battle of the brains.

It's no Spectacular, which I still regard peak modern Spider-man cartoon. But better than nothing I suppose.
How many cartoon of Spider-Man have been released.
I have watched at least 4 of them, including the weird Spider-Man Unlimited (1999), but I feel like there are still a lot that I missed.
Only Sega Mickey Mouse game I played is Mickey Mania.
While it's good capturing the transition / evolution of old to new cartoon, Mickey Mania isn't made by SEGA.
Castle of Illusion and World of Illusion (plus QuackShot) really have that 16-Bit SEGA DNA that we can feel when playing it.
