LOS ANGELES — Rocket Raccoon and his fellow “Guardians of the Galaxy” are getting their own television series.

Expanding an effort to put its XD cable network on the ratings map, Disney will introduce an animated show next year based on its film “Guardians of the Galaxy,” which has taken in $324 million at the domestic box office, by far the No. 1 movie of the year to date.

The animated show, produced by Marvel, will join another prominent new series made by a corporate sibling for Disney XD: Lucasfilm’s “Star Wars Rebels” begins its run on Monday. “We have more exciting collaborations in the pipeline,” said Gary Marsh, president of Disney Channels Worldwide.

The goal is to find Disney XD’s first true hit. While defending the lightly watched channel as an overall success, Mr. Marsh conceded that some programming efforts had fallen short. “I don’t think we have yet found our defining show,” he said.
