I could only read the climax of a comic novel which was published in a magazine. The ending was as follows:
The hero and and his crew are sailing in a space shuttle. The hero, who looks like a cyborg is saying that he was given half the life span of a space dragon (means the dragons are flying in space, not in air), by a witch-like lady. The story ends where their space ship is approached by lots of space dragons, but they manage to sail through.
Further details:
It was a comic book published in the 20th century.
The drawings were all quite realistic and followed the western/american art style.
All the human characters looked like white people.
The witch had given some job to the hero, for which she gave him the half life of the dragon.
