8. A Connection To Uprising
Despite being part of the series' canon, the animated Tron: Uprising didn't get the chance to spread its wings for too long before Disney unceremoniously dumped it. Taking place after Clu's betrayal of Kevin Flynn and Tron, the series followed a young program named Beck as he was trained by Tron himself to protect the Grid. While it took some minor liberties, Uprising fit rather neatly into the overall story and earned a small but loyal following over its brief run, though it remains a tale left relatively unfinished. Taking into account the low number of people who actually saw it and the fact that Tron 3 will likely have bigger fish to fry as it leaves Clu's oppression behind, no one is expecting Uprising's characters to make the jump to live-action. That said, it wouldn't be hard for someone else - Tron, perhaps - to make a passing reference to Beck or events seen in Uprising to give the show's fans a consolation prize for their loyalty.
