Birdman Cartoon Series

A foreign gang plots to divert an American solar capsule to their landing station by changing places with the astronauts just before the launch. Replacing a city supply train with one of their own, they start toward the site, but Birdman and Avenger rush the train and battle against super-weapons only to lose the gang in a tunnel. Birdman reaches the launching site just at blast off to ground the train tricksters for good.

Birdman and Avenger are called in to help when a non-human replica of an army defense general stirs up trouble. In order to get inside the headquarters of the evil professor, who is kidnapping people and replacing them with his duplicates, they fight off a replica Birdman and Avenger. They free the captive by pitting the professor and his duplicate against each other.
