Sparkster the Rocket Knight (partially found unpublished follow up for "Sparkster: Last of the Rocket Knights" comic series; date unknown)
From The Lost Media Wiki
After making the first six-part story of Sparkster: Last of the Rocket Knights, Nigel Kitching started making a sequel, but it was cancelled when Fleetway couldn't get the rights from Konami to use the character.
Apart from some pictures of the comic found on Keith Page's blog, very little information is available on it.
