storyline The Justice League sent Batman to Cuba when aliens invaded. He uncovered the aliens' gun running operation, exporting the weapons in cigar cases; Batman reported his findings to Commissioner Gordon. Investigating further, Batman was attacked by Thanagarian Aerial Guards - hawkmen. He escaped them and blew up the cigar/gun factory.
S.T.A.R. Labs created a perfect artificial diamond which could fire a laser to perfect precision. Mr. Freeze escaped while being transported from Arkham to a prison and went after the laser. Batman was briefly captured by Freeze, but he defeated him.
