The Hulk would beat him up. Martian Manhunter will say that Hulk is making a fool of himself but Hulk would punch him in the arm. Hulk would punch him into the wilderness and fight him there. Hulk will punch him 5 times to knock him out and get out of the wilderness.

Batman is known for having contingency plans in case the league were to go rogue, so this would include a way to beat Martian Manhunter. Martian Manhunter's weakness is fire, something that isn't hard to acquire especially for Batman. So in a fight where Batman can use any tricks and gadgets he wants, Batman would win hands down.
As strong as Superman He said so in Green Lantern 44 Martian Manhunter has always certainly been on par with Superman physically. However, he is not quite as strong as Superman. Although the Manhunter is more powerful overall, Superman is physically stronger.
Yes, Martian Manhunter has a shapeshifting alien creature named Zook who often takes the form of a dog. Zook is a loyal companion to Martian Manhunter and has been featured in various comics alongside him.
First of all do you mean Martian Manhunter or the Manhunters? The Manhunters were a corp created by the Guardians of the Universe before they created they Green Lantern Corp. If you mean the Manhunters then Green Lantern wins at all aspects but if you mean Martian Manhunter then its a little more complicated. If by better you mean more powerful, then Martian Manhunter will probably win. Although the power of the Green Lantern varies from Lantern to Lantern none of them can protect themselves from Manhunters phsychic attacks. Manhunter could stay intangible while attacking Green Lantern and the worst Lantern could would be start a fire (Because Martian Manhunter has a phobia of fire) But if by better you mean being the better at being a superhero. The matter is a little bit more complicated. They are both founding members of the Justice League and overall good people. I would have to say there pretty even at being superheroes. Hope I helped, also next time try to word your question better. State what you mean by better and accurately who your asking about (There are quite a few Green Lanterns, I was talking about the most popular one which is Hal Jordan)
While Martian Manhunter is certaintly one of the most powerful heroes within the DCU, he isn't the strongest and can be defeated easily, his main weakness being fire and I can think of 6 fire based villains in the DCU without thinking. In terms of all around strength and power I'd say Spectre is the strongest hero in the DCU, but as far as story and mythos Batman would be the best.
You can ask a Martian why they don't exist.
BTW Martin Manhunter is in DC but anyway hulk will win as he is invunerable to almost all of man hunters attacks. The hulk is all-terrain and would even defeat him in Mars.
This fight would never happen, no matter how you look at it.
Martian
