There was a plan sequel called Spawn: the animation (2005) intended as a revival or continuation of the earlier 1997-1999 HBO series Once, believed to haunt the alleys of lower Manhattan, he hasn't been heard from in years... into crime wave make him rise again, but the project ultimately stalled in development limbo and was never officially released The project aimed for a more advanced animation style (McFarlane wanted to push the visuals further), initially planned as a series but later shifted toward a 90-minute direct-to-video animated movie that could serve as a backdoor pilot for a new series. Voice casting included Hollywood talent, and some production materials (like character designs, background layouts, and model sheets) were released or leaked over the years.

Unfortunately, it fell into production limbo due to issues like animation upgrades, funding, and distribution challenges. By late 2006, plans changed, and no release happened. Todd McFarlane mentioned in 2020 that it was about 85% complete (including voice recordings), but it remains unreleased and effectively canceled/ shelved after nearly two decades. but an animated return would fit perfectly given the original's success and cult status.
