While Sonic celebrates his own anniversary, another certain hedgehog and his allies celebrates their 20th anniversary, although it's kinda more...tedious than the other one.

Also Black Doom is here, because what else is good to do besides taking over the Earth?

Happy 20th anniversary, Sonic Adventure 2.

And YES, I KNOW THAT SONIC ISN'T HERE YET THE TITLE IS CALLED SONIC 4 IN IT. Technically still counts since...well, they're all characters from Sonic.
