Red Sky seasons

The Red Sky seasons or Red Sky years is a popular term referring to seasons 8–10 of the 1987–1996 animated television series. During these seasons, the tone of the series changed.

In many episodes, the skies of New York City looked reddish rather than blue. A lot of the action also returned, and the storyline became darker. The humour was also reduced, and many of the characters were gradually written out of the series. During season 9, Dregg became the main villain of the series.
