The most powerful object in the universe, the INFINITY SWORD, has been shattered (oops!) in a battle between IRON MAN and DR. DOOM. But Doom doesn't give up easily; he'll leave no stone unturned until he recovers every last shard. Iron Man snags the best heroes around to beat Doom at his own game: WOLVERINE, HULK, THOR, the SILVER SURFER and a hotshot flyer named THE FALCON. With friends like CAPTAIN AMERICA and MS. MARVEL, and with tons of other heroes helping out, Iron Man can lead the Super Hero Squad to victory!
