On the day of James Kirk's birth, his father dies on his ship in a last stand against a mysterious alien time-traveling vessel looking for Ambassador Spock, who, in this time, is also a child on Vulcan disdained by his neighbors for his half-human heritage. Twenty-five years later, Kirk has grown into a young troublemaker. Challenged by Captain Christopher Pike to realize his potential in Starfleet, he comes to annoy instructors like young Commander Spock.
Batman, the costumed crime-fighter who prowls the night skies in Gotham City, soon finds there's another vigilante in town knocking off prominent mob figures. Despite the scythe-like blade for a hand, a mechanical voice and the cloud of smoke that follows the figure wherever it goes, the police and outraged officials mistake the homicidal crusader for Batman himself and demand that the city's longtime hero be brought to justice. Meanwhile, Andrea Beaumont returns to town.
