LEADING THE ATTACK: If Superman is adjacent to an opposing character at the beginning of your turn, he can make a close combat attack as a free action, but he can't attack that character again during that turn. If Superman causes a target opposing character to take damage, until the end of the turn all friendly characters attacking that target have their attack values modified by + 1 for each 100 points (or fraction thereof) of the target's point value.


When Superman is adjacent to an opposing character and get's his free action attack and misses, since he can't target that same character for his normal attack, does he have to roll for breakaway to try and attack another non adjacent character? Or does he simply end his turn if another opposing character is not adjacent to him?

The only thing that special power does is prevent him from targeting the character with an attack again. So he can still try to move away to attack another opposing character.
