Space Ghost is the host, his enemies
Zorak and
Brak are held prisoner and forced to help him on the show.
Zorak is somewhat restrained to his
Prison Pod,
Brak on the other hand is just sorta stuck at a table..
Instead of having guests on this show they had a
mailbag, a
Monday Ratings Report, and sang songs.
Which they somehow manage to make totally hilarious.
Unfortunately
Cartoon Planet is no longer on
Cartoon Network, although
Space Ghost Coast To Coast and
Brak Presents The Brak Show Starring Brak are.
