The New Adventures of Batman is a cartoon made by Filmation, who in the past, has made cartoons based on DC Comics. However, this was made in a time when Hanna-Barbera was making its Super Friends cartoon, and also in a time when TV standards had changed.
Here, Batman and Robin (voiced by Adam West and Burt Ward, reprising their roles from the TV show that aired during the 1960's) continue their never-ending battle against criminals who threaten Gotham City. This time around, they are joined by Batgirl (voiced by Melendy Britt), and, possibly as a demand from the networks, they are aided by Bat-Mite (voiced by Lou Schiemer, an imp from another dimension known as Ergo (which is different from the Bat-Mite in the comics) who is Batman's biggest fan and wants to help, only for his tricks to sometimes end up hinder the Dynamic Duo instead.
This cartoon is a product of its time. As Filmation got into hot water with parental groups over the New Adventures of Superman cartoon due to its display of the typical violence and fisticuffs seen in the comics it was based on, which led to its cancellation, New Adventures of Batman would end up doing away with those as the networks were now wanting to do away with such violent content (the same reason why Super Friends, for most of its run, did not have violence of any kind, and was more of a light-hearted show). The New Adventures of Batman would do the same, as the series instead shows the detective side of the Dynamic Duo (and if needed, their wide variety of gadgets). And Bat-Mite I can understand, as he is more of a hinderance than help (making Bat-Mite another Scrappy that was put in because the network thought younger Bat-fans would like him).
When it comes to villains, this is also impacted. As this series aired alongside Challenge of The Super Friends (which also had Batman and Robin), there would be many villains that would be restricted to one cartoon or the other, and with this show, The Riddler is off limits (despite being seen in the intro in a pink outfit, and being mentioned in an episode), as well as The Scarecrow, as both appear in CoTSF as members of the Legion of Doom. However, NAoB would be able to use Batman villains like The Joker, Catwoman, Mr. Freeze, and even Clayface, the fourth villain making his television debut in this series, as well as original villains like the Sweet Tooth, Professor Bubbles, and Zarbor.
Basically, the episodes are all written to be light-hearted, with some corny jokes and the end of each one having a segment teaching a moral related to the adventure the Dynamic Duo went through. This is more of a show for younger superhero fans due to the more lighthearted nature it takes due to the standards of the era this first aired, as older Batman fans will hate Bat-Mite and the tone.
