Welcome back to our annual Mouse Madness tournament! This year, our champion will take home the title of best film of the Marvel Cinematic Universe…so far. We’re looking at 16 of the 18 films (sorry Hulk and Spidey) to determine which story is better than the rest.

Sometimes the first impression is the best. Yesterday’s match up went to Guardians of the Galaxy as they beat out Vol. 2 with more than 70% of the vote.  Round 2 will see them facing the Avengers in an exciting battle. Stay tuned to see what happens!

Iron Man 3 has Tony Stark creating Iron Patriot to fend off some scary threats, developing more impressive tech, and working with his supportive team—Pepper Potts and best friend Rhodey. His challenger is Scott Lang aka Ant-Man. Scott’s a criminal who gets a chance at redemption when he meets scientist Hank Pym. Pym (who worked with Tony’s dad) designed a unique suit that alters the wearer’s atomic structure allowing them to shrink to the size of an insect. Together they work to prevent Pym’s technology from falling into the wrong hands.

Does Ant-Man have what it takes to catch Iron Man off guard? Vote now:

Be sure to come back tomorrow as we reveal the winner of today’s poll and continue onward through our bracket to crown the best film in the Marvel Cinematic Universe champion!
