I'm personally going to add Detonator Orgun to the legitimately good pile. In particular, if you like Tekkaman Blade, you'd probably enjoy it.
While it does have unique aspects to the story, you can see Tekkaman Blade clearly lining up with this; most of the major characters have a rough equivalent. There's a whole bunch of little plot beats that seem like they carried over - for example, both Orgun and Blade transform into bio-mechanical beings even though it looks like they're wearing armour.
The action is also outright better, I'd say, since Orgun seems to prefer melee combat rather than spamming his beam attacks.
I'm actually not sure how one lead to the other, though. I know Obari's the director of Orgun and worked on the opening sequences of Tekkaman Blade, but there were different writers, a different director, a different studio. Did they both get this stuff from the original Tekkaman? Was Tatsunoko just heavily inspired by the OVA?
