MvC2 Color Chart +++
MSH alternate color Magneto was top tier. It was so good they had to hide it behind a code. I think you had to move the cursor to the character, then hold up for 3 seconds (or down if they are on the bottom row), then press a button. All of Magneto's colors look the same in MvC2. I will contribute $5 to the yellow Magnus fund.
