Lost Heroes, Part One

**"Lost Heroes, Part One"** is the first part of the season finale of the fifth season of *The Batman*. It is also the sixty-fourth episode overall.

## Synopsis

The super-powered members of the Justice League begin disappearing one by one. Only Batman, Robin, and Green Arrow are left to investigate and discover that their old enemies and The Joining are involved.

## Plot

As the episode opens, Batman and Superman are trying to capture Toyman. During the fight, bombs go off, and as the smoke clears, Batman finds that Superman is missing. At the same time, Flash and Green Arrow are trying to find Mirror Master at the Central City Fairground. The two defeat him in a carnival house of mirrors, but from behind the mirrors, barrels open to release a gas that knocks out both heroes. Just before he blacks out, Green Arrow sees Flash being dragged away.

At the Batcave, Batman, Green Lantern, and Green Arrow convene with Martian Manhunter that Hawkman had been taken too. The remaining Justice League concludes that Batman and Green Arrow were not taken because they have no superpowers. When the Justice League goes in search of Superman and Flash at the carnival, they are attacked again, this time targeting Martian Manhunter with fire and Green Lantern with yellow electric droids. Batman and Green Arrow put out the fire, but their comrades are gone when the smoke clears.

While working on trying to find the heroes using the strange radio transmitters from the barrels that knocked out Flash and Green Arrow, Batman falls asleep. He has a vision of the five kidnapped Leaguers restrained and glowing with power, and an apparition of the Martian Manhunter repeats to him the name "Hugo Strange".

Batman & Robin along with Green Arrow go to Arkham, where Dr. Strange is supposedly incarcerated. They see Mr. Freeze being taken to his cell by a guard, and they pass by the Joker's cell, to which he turns his head to look at them and smiles, they then enter Dr. Strange's cell. However, the inmate they meet is not Strange himself but an alien robot duplicate. Together, the heroes disable the robot, and Batman retrieves its radio transmitter. Tracking the transmitter's signal, the three remaining heroes arrive at an air raid bunker, which they break into; they are promptly captured by the real Hugo Strange, who was hiding out there.

Dr. Strange smugly reveals the captured Justice Leaguers, each of whom has a tube attached to his chest carrying blue light away from him. Strange discloses that he is working with aliens called the Joining, who invaded Earth before but were stopped by the Justice League. Strange proposed to help the Joining by neutralizing the Justice League in exchange for the "knowledge of the universe."

Batman & Robin with Green Arrow manage to break free of their restrains and cut loose their friends as well. When they do, they unveil five androids, each of which has taken on the powers of one of the kidnapped Leaguers. When the Justice League tries to fight back, they discover that the kidnapped superheroes-Superman, Green Lantern, Hawkman, Flash, and Martian Manhunter-no longer have their powers at all.
