Synopsis for "The Origin of Killer Moth!"
While in prison, one of the inmates collects every piece of information and memorabilia about Batman's greatest feats. Upon his release, the inmate adopts the identity of Cameron van Cleer and becomes a wealthy socialite in Gotham City. Cleer buys a mansion and starts constructing a cave underneath the house. All this with the sole purpose of recreating Batman's arsenal and base of operations. Finally, Cleer is ready for action and he becomes the criminal aid known as Killer Moth.
Killer Moth
Using his new moniker, Moth contacts the underworld and informs them that he is going to operate exactly like Batman, only he would help crooks instead of capturing them.
Soon, both Batman and Killer Moth are summoned to action and they confront in a duel of wits and equipment. Killer Moth uses his own Mothmobile to knock Batman and Robin unconscious and take them to the Moth-Cave, where he forces Batman to take him the real Batcave or else he would kill Robin. Batman and Moth are on their way to the Batcave and in the meantime, Robin manages to break free and goes to the GCPD Headquarters, where he uses a radio to contact Batman and prevents him from showing Moth the Batcave. Learning that his plan has failed, Moth tries to escape by climbing over a bridge, but Batman follows him closely. They struggle for a few moments until Killer Moth falls to the river below. The police and Batman try to find Killer Moth's body, but it seems as it has vanished away.
