 In the third season episode "Hawk & Dove", the bickering brother  superheroes, Hawk & Dove, are voiced by Fred Savage (qv) and  Jason Hervey (qv), who played the brothers on the TV series  _"Wonder Years, The" (1988)_ (qv); unlike "Wonder Years", however,  Savage voiced the older, more aggressive brother (Hawk/Hank Hall)  while Hervey voiced the younger, more docile brother (Dove/Don  Hall). It was originally intended for their relationship to match  "Wonder Years", but during the voice reading session, they  unexpectedly switched roles for one of the readings and that was  kept for the episode.
