- Mild
- Several female characters wear form-fitting outfits that accentuate their breasts and buttocks to an extent
- Catwoman acts a little sensual around men, especially Batman
- Barbara is briefly shown in a state of undress while putting on her costume.
- Some characters kiss. One time, a kiss is forced upon a main character without their consent.
- Some mild innuendos. The worst example is a female villainess makes sounds as if she's coming to climax during the literal climax of an episode in season 4.
