Gorilla Grodd

Gorilla Grodd is a staple character in the Flash’s Rogue’s Gallery. He’s a superintelligent gorilla from Gorilla City, a highly advanced metropolis and he has the ability to use telepathy and is super strong.

Gorilla Grodd is public domain due to a failure to renew Flash #106 from 1959, meaning the copyright expired in 1988.

Barry Allen and other Flash characters remain under copyright. I also could find no trademark for Gorilla Grodd, but maybe i just didn’t search thoroughly enough.

Captain Z-Ro

Captain Z-Ro was a space opera serial from the 50s playing off popular serial characters like Buck Rogers and Flash Gordon.

He had a device called the ZX-99 which was a time machine used to view the past but also send people back in time, usually in order to alter it in some way. While it was always used to go back in time, mainly as a way to teach kids history it stands to reason the ZX-99 could also travel into the future.

The serial was not renewed and subsequent renewal efforts in the 80s were rejected by the copyright office.
