Leo Nardo Stands Alone! Two months after defeating Superfly,[a] the Turtles—Michelangelo, Leonardo, Raphael, and Donatello—are now revered as heroes by New York City. On their way to a costume party, the Turtles encounter a villain, Bishop, who has an agenda against mutants. Their plan to defeat her backfires, resulting in their separation across the city. Leonardo winds up in an alleyway and is chased by one of Bishop's mutant-hunting robots called a "Mechazoid." After losing the Mechazoid, Leonardo makes his way to the party and meets up with April O'Neil. Together, they badly damage the Mechazoid. Meanwhile, Bishop watches on monitors as the other Turtles are menaced by Mechazoids.
