Without a doubt Shadow The Hedgehog is my favourite Sonic The Hedgehog character. One of the best enemy to ally/rival transitions the series has ever had. From his history with Maria, the ark, the black arms, and his chemistry with Team Dark there's a lot to love.
He has been a prominent part of my childhood as well as the series as a whole and still to this day is a character I adore. I cannot wait to see him on the big screen in Sonic The Hedgehog 3 and in Sonic X Shadow Generations later this year!!
