I think they are good. The Martian Manhunter comics usually offer interesting adventures and explore his unique powers and personality. However, like any comic, it might not be for everyone.
I think it's quite good. The storylines are engaging, and the art is often top-notch. However, it might not be for everyone as it can get a bit complex at times.
A fanfiction could explore a scenario where Martian Manhunter is sent to Amity Park to investigate some strange paranormal activities that Danny Phantom has been dealing with. This could lead to an interesting dynamic as they both try to figure out what's going on while also learning about each other's abilities.
Well, it's difficult to say whether there is such a fanfic. Fanfic writers come up with all sorts of creative ideas, but this particular combination of Martian Manhunter and M Gahn in a pregnancy - related story might not be very common. There are so many different fanfic universes and themes out there. It could be that someone has written it, but it might also be that no one has thought of it yet or it's just not popular enough to be easily found.
They could start off being cautious of each other. Danny might be a bit wary of the Martian Manhunter's powerful telepathic abilities, while Martian Manhunter could be intrigued by Danny's unique ghostly powers. Eventually, they would realize they can work together well.
It could be about how they deal with the unexpected pregnancy. Maybe they face challenges from their respective communities or families. Or it could explore the unique biology of Martian Manhunter in relation to the pregnancy if he is the one carrying the child.
One interesting plot point could be the cultural differences between the Martian Manhunter and his wife. Since he's from Mars and she could be from Earth or another planet, they would have different values and ways of life. Another plot point might be her reaction when she first discovers his true form.
Well, I'm not sure about a specific title at the moment. But in general, a good 'Martian Manhunter wife fan fiction' would likely involve elements like her understanding his powers and how they navigate life together. It could also focus on her being part of his adventures, like in a story where she helps him defeat an enemy by using her own unique skills that complement his.
