Key Monster

The Key Monster appeared in season 2 of 1994 TV series called Mighty Morphin' Power Rangers. Lord Zedd gives this Key Monster an important assignment—he serves as the Gatekeeper to Lord Zedd's Haunted Forest where Doomstone dwelled. He must make sure that it stays locked up. After having trouble finding the right key, he uses his master key to lock it up and not allow anyone who enters to escape. Tommy gets locked up in the dimension after getting tricked by Goldar and a bunch of Z-Putties disguised as children in Ranger costumes. The Key Monster is not shown battling the Rangers, and is never shown being destroyed.
