Future
In April 2014, in an interview on Steve Agee: Uhhh podcast, Brendon Small confirmed that a fifth and final season was in pre-production. Small was originally waiting on Adult Swim for an appropriate budget in order to end the show the way he wants rather than rushing it. But after pitching the idea for the finale to the network, they turned it down, stating that they did not have the budget for it.

In October 2015, Brendon Small announced a month-long social media campaign entitled "Metalocalypse Now" as an attempt to gather fan support to have Hulu and Adult Swim co-finance the final season of Metalocalypse. At the time it was thought to be successful, the finale to be titled: Metalocalypse: The Army of the Doomstar – The Final Chapter, and would be a miniseries on Hulu Plus.

In May 2016, Brendon Small said in an interview that he is "all but finished making Dethklok records" due to Adult Swim declining to continue with the final season despite popular support of the continuation. Small stated that as a result of the "Metalocalypse Now" campaign, financial backers had come forward to fund the Metalocalypse finale, but Adult Swim ultimately did not want to go forward and make a finale. Small stated that he does have plans to eventually finish the Metalocalypse story, but he cannot say how.

On May 12, 2021, Adult Swim announced a direct-to-video film is in development and will be released on home video and digital followed by streaming on HBO Max 90 days after along with a broadcast premiere on the channel.
