All the way to super meat boy 2 i think!!!
This character has got to be (if they make another one) in super meat boy 2. It is a great charater, it's differant, the levels have spikes, he's red, you've got him to be red, he has the wall jump and he even has the bit where wen you die you explode and blood comes out of you. It's a great game and a great character :)
