A Greater Ape
"A Greater Ape" was an unproduced episode planned for Beast Wars' first season, written by Katherine Lawrence. "A Greater Ape" came up during Bob Forward and Larry DiTillio's panel at BotCon 1998; it focused on Optimus Primal who, after a blow to the head, believed himself to be an actual gorilla. He ingratiated himself into a group of gorillas, even romancing a female ape, until an attack by Megatron on the gorillas brought him back to his senses; his gorilla ladyfriend rejected the real Primal. Mainframe was unable to produce it because it would have required too many new models.
