One of my favorite series that was part of a wave of spinoffs back in the early 2000’s was the Cosmo Warrior Zero property that gave us more Captain Harlock.
Naturally, with it being based on a home video license, it’s only available for viewers in the US and Canada.
The show got picked up originally by Media Blasters back in 2002 and Discotek Media rescued the lapsed license back in 2017 with a release.
