Kramer

Kramer has conflicting personality traits. He is sometimes shallow, callous and indifferent. Though eccentric, Kramer is generally caring, friendly and kind-hearted; he often goes out of his way to help total strangers, and tries to get his friends to also help others and to do the right thing even when they do not want to. He is confident in his own unique way of doing things, yet he can be neurotic and highly-strung. His quirkiness, strange body movements and frequent gibberish mutterings have become his trademark.

Kramer was originally envisioned as a recluse who never left his apartment except to visit Jerry.[5] This was the original reason behind why Kramer helps himself to Jerry's possessions and food without any pushback and also why he is conspicuously absent from the season two episode "The Chinese Restaurant," which takes place entirely outside of the building. However, in season three Kramer starts to join Jerry, Elaine, and George in various scenes outside of the building. As the series progresses, Kramer completely loses any hints of reclusiveness and becomes one of the most extroverted characters on the show.
