Fan Casting Sonic the Hedgehog 4 (with most likely news)

(BTW, the poster is OFFICIAL concept art, and this is only because I wanted to get it out of my system. Enjoy!) Our hedgehog hero is back, and it's bigger than before!!! Robotnik has survived, and has used the Super Sonic quill to conquer civilizations and rule the world as he wanted! Sonic, and his new friend Amy Rose, will have to face Robotnik and his greatest creation, Metal Sonic, to save the world and get Sonic back home!
