[2] Complicating matters is Bat-Mite, a well-meaning imp from another dimension called Ergo, who considers himself Batman's biggest fan.

Missing is Alfred, the faithful butler of Batman's alter ego Bruce Wayne; also notable in this series are the inverted colors of the circled "R" on Robin's costume.

[4] In September 1968, before The New Adventures of Batman, Filmation had created and aired an animated series named The Batman/Superman Hour for CBS.

As with the prior Filmation produced Batman series, no backstory or alter ego were presented for Catwoman within the four episodes in which she appeared.

Penguin frequently rolls his 'r's and laughs in a manner similar to Burgess Meredith's portrayal, although he has a high-pitched posh accent.

He appears in "Reading, Writing and Wronging", "Birds of a Feather Fool Around Together", and "Have an Evil Day, Parts 1 and 2".

He and his henchman Professor Frost plot to steal the N-1000 (a superfast submarine) to pull off the "Crime of the Century".

Clayface escapes by water, but Batman pursues him in his Bat-Boat until the former's potion wears off and he nearly drowns due to his inability to swim.

In the two-part episode "Have an Evil Day", Zarbor enlists Clayface, Catwoman, the Joker, and the Penguin to keep the Dynamic Duo busy while he steals America's nuclear power plants.
