Gargantuan Assault: Batman/Superman Robot can use Multi-Attack.
Colossal Retaliation - Asteroid-Level Impact: Give Batman/Superman Robot a free action if no other Colossal Retaliation power has been activated this turn and choose an opposing character that attacked Batman/Superman Robot or damaged a friendly character since your last turn. Place Batman/Superman Robot such that it can make a close combat attack targeting the chosen character, then do so with an area of effect that includes all other characters within 2 squares of the target. Hit characters are each dealt 2 penetrating damage instead of normal damage. After actions resolve, destroy all blocking terrain within the area of effect of the attack and place debris markers in all clear terrain within the area of effect of the attack.
Colossal Indifference: If Batman/Superman Robot began the game on the 25-point starting line, it can't attack smaller characters except via Colossal Retaliation. When this power is revealed due to damage taken from opposing character's attack, stop turning the dial. This power can't be countered or ignored.
Metallo Alloy: Batman/Superman Robot can use Impervious, but if it would be dealt 4 or more damage, it reduces that damage by 3 instead of 2. This power can't be countered.
