[Guyver Spawn]

For people who enjoy Devilman: Crybaby, here are other titles from Go Nagai that I recommended to check out.

Demon Prince Enma - A soft sequel/reboot to the original Enma-kun. This series features demon hunters and has a similar dark tone with blood, gore and hellish looking monsters.

Demon Lord Dante - The manga that Go Nagai created before Devilman. The TV series has a weak animation budget and a somewhat confusing ending. It is still worth checking out in my opinion.

Devil Lady - A spin off series and it is different from the manga. I still think it was pretty good in my opinion.

Getter Robo Armageddon - I know Getter Robo is mostly Ken Ishikawa work, but it is still excellent. This is one of the best Super Robot Wars anime in my opinion. I consider it to be better than the original Getter Robo series.

Mazinkaiser - I don't like it as much as Shin Mazinger, but it's still good in my opinion. I also have a soft spot for it because it was my first Go Nagai title that I saw on a VHS fan sub copy back in the day.

Mazinkaiser SKL - Another mecha series. Heavy metal as fuck!

Shin Mazinger Shougeki Z-hen (Mazinger Edition Z: The Impact!) - Another modern version of a Go Nagai classic. I remember it even has references to the Devilman manga panel for panel. The animation is way ahead of it's time in my opinion.

Shutendoji - Another horror series from Go Nagai. The main character in Shutendoji also loses his humanity to battle demons.

Violence Jack - The sequel series to Devilman, but it stands on it's own. The manga never got fully translated. So you may have to set with the OVAs for now. The OVAs are pretty much grindhouse exploitation films. They are not for everyone.
