Burt Ward is a fictionalized character of the actor with the same name who played the role as Robin with his friend Adam West who played the role as Batman in the 1960s Batman TV series. In the episode "Pharaohs", he reunited with his friend, Adam West, playing the role as King Adamnoken the Second (nephew of King Adamnoken the 1st who is voiced by Adam himself). After that, he has not made anymore appearances or references of the show but is seen in a picture with Adam West when Burt was 20 years old in the Catman years. No one seems to mention him in the show making him non-existing to the other characters. There will be an upcoming episode "Catman and Catboy" featuring Burt Ward coming to the AnimeLand for the first time and seeing them both united.
