Avengers vs Masters - YOU DECIDE WHO WINS!

Who's really the Mightiest?  Who's really the Most Powerful?  YOU get to decide!  Starting tomorrow (5/5/12) I will be posting one showdown per day for the next week.  You get to vote by leaving comments on the sivARTblog as to who wins each round.  Feel free to elaborate in your comment as to why you chose the character you chose to win.  After the week is over I will add up the winners and announce which team is really the greatest!

Let the games begin!!!
