green mountain but reverse he's called beginning instead of end. he was a rejected sonic clone made by eggman. he thinks he is the real sonic (2nd sonic is what he sees himself as) his whole world is red because eggman turned the sun red for some reason. this makes the game kinda look like a virtual boy game. i think the actual game would be a mix of sonic and celeste. he has protanopia (red-blindness) which makes him see red as blue. his game would kinda be the opposite of green mountain. you are playing as tails, flying in the tornado. suddenly, the plane starts to crash, and you end up at the top of a mountain called, the crimson peak. you would start at the top of the mountain with "sonic", and you have to guide him down, facing badniks, other clone sonic rejects, and robotnik's traps along the way. once you reach the bottom of the mountain, it is revealed to turn into a giant eggman mech, which you have to defeat. once you defeat it, the world turns back to normal, but "sonic" runs away, never to be seen again. at least by tails. so show me, all of which I must see, even if it needs me, even if I can.. oh it tolls you, on the mountain with me. never staying constantly awake..
