The Martian Manhunter aka J'onn J'onzz had a smaller appearance in Justice League: Crisis on Two Earths but it showed his romantic side which I liked very much.
I saw the Martian Manhunter in the Justice League cartoon series and he is similar to Batman in many ways. Both of them never laugh or make any jokes. They always look very serious and both of them lost their families which affected them very much.
Rose Wilson likes his father very much but she does not like the fact that his father does not take any actions against the crime syndicate. She argues with her father and during this argument she first encounters the Martian Manhunter as he accidentally read her mind. The two grow further close when the Martian Manhunter saves her from the archer.What I like about Rose Wilson is that she was not intimidated by the appearance of the Martian Manhunter and liked him for who he is. That’s why I like this romantic angle. I have great respect for those who does not judge their lovers by how they look but who they are. At the end of the story, I really felt sad that J’on J’onzz leaves her.
