Scholastic Books, the folks behind R. L. Stine's family of youth horror books, saw the success Fox had adapting Goosebumps for television, and sought to find another series that was ready for television.
The company and its television arm partnered with YTV in Canada and Nickelodeon in the US to produce Animorphs, based on the book series of the same name. The TV version began in 1998, but lasted just 2 seasons (26 episodes).
The plot deals with a random group of teens recruited to fight off an alien invasion, granted the ability to morph into various animals and insects. Series star Shawn Ashmore later landed a primo gig in the "X-Men" movie series, and is the only cast member who'd actually become a success coming out of Animorphs.
So far, Scholastic has resisted the urge to license the now-defunct series into comics. Had they done so, and, say, DC picked up the license, I get the feeling the Animorphs would get a visit from a couple of DC heroes already accomplished in animal morphing......!
Anyway, the mistake Nick made was putting Animorphs in primetime, rather than on Saturday mornings, where it would've garnered a bigger audience. Problem was, Nick suits were obsessed with running blocks of certain "hot" cartoons of the period and left themselves no room to fit this series into their Saturday morning block. Their loss.
