What is nina on seinfeld?

Nina is a character on Seinfeld, who appears in the Season 3 episode "The Alternate Side". She is played by actress Justine Bateman.

Nina is Jerry's girlfriend for a brief period of time. She is an artist and is working on a mural in Kramer's building as part of a restoration project. Nina is creative, intellectual, and introspective, but also very high maintenance and demanding of Jerry's attention.

During their relationship, Jerry becomes frustrated with Nina's constant neediness and her tendency to monopolize conversations. He eventually breaks up with her after she insists on him attending her performance art piece, which he finds exceedingly pretentious.

Overall, Nina is portrayed as a challenging and somewhat unlikable character, but also a humorous foil to Jerry's more laid-back approach to life.
