Unfortunately, the show was canceled after airing 26 episodes, only half of what was initially planned. Fans of the show had worked hard to convince Warner Bros. and Cartoon Network to give the series a second chance, including an online petition and sending feedback through email and social network sites like Facebook, Twitter, and Tumblr, and suggesting it for crowdfunding on http://www.smgo.tv/.
Another reboot with a greater emphasis on comedy, titled ThunderCats Roar, was announced in 2018.
