Nearly 30 years later, a television adaptation of Batman revitalized him once again. Batman: The Animated Series retold Mr. Freeze's origin in "Heart of Ice", an episode by writer Paul Dini. The episode introduced his terminally ill, cryogenically frozen wife Nora, which explained his obsession with ice and need to build a criminal empire to raise research funds. This more complex, tragic character was enthusiastically accepted by fans, and has become the standard portrayal for the character in most forms of media, including the comic book series itself, which previously had the character casually killed off by the Joker. Freeze was resurrected in the comic after the episode aired.
The episode was seen as groundbreaking for a Saturday morning cartoon and helped set the tone for the rest of the series. This back story was also made canon in the comics and has been the character's official origin in almost every incarnation of Batman until New 52.
