 This series was created by Bakshi, Ralph (qv) at a pitch session  where Terrytoons offered their show concepts to the CBS executives  only to have them all rejected. While the producers were in shock  and preparing for unemployment, the network executives asked the  group if there were any other concepts they could hear about.  Bakshi, a junior animator who was allowed to sit in on the session  provided he sat down and stay quiet, immediately piped up and  improvised the concept for the Mighty Heroes series in front of the  suits. The idea was accepted and Bakshi was given responsibility for  directing it.
