Theo

Theo is the proud and regal father from the PBS children's television show Between the Lions. He is a bit scruffy in appearance but has a deep, masterful voice perfect for storytelling. Theo has been performed by Peter Linz since the second season. He is married to Cleo, and has two children who are the hosts of the show. Leona and Lionel. Theo has also made numerous appearances at conventions, benefits, etc.

Theo, like all the other lions but more so, is usually hungry and requires a great deal of sleep.

In 2002, Theo appeared in an interview on NPR's Morning Edition along with executive producer Judith Stoia (whom he addresses as "Judy"). He described briefly the content of the show and answered a couple questions in character. He and Stoia described conflicts between different schools of thought in language education as well as a funding shortfall. The interview is punctuated with audio clips of songs from the show.

In one interview, Linz confessed to control Theo's mouth and eyelids with his right hand and Theo's left hand with Linz's left hand. Someone else would operate Theo's right hand.
