From wikipedia:
Powers and abilities
Martian Manhunter has been described as "the Swiss Army knife of superheroes," possessing a variety of super-powers, many of them are similar to those of Superman, including superhuman strength, speed, durability, flight, and "Martian vision" (a power that includes both x-ray and heat vision). In various altercations with Superman, Martian Manhunter is usually able to hold his own against the Man of Steel, but ultimately loses the fight; however, he has fought Captain Marvel to a standstill.
J'onn is a very powerful telepath, capable of perceiving the thoughts of others as well as projecting his own thoughts. He often acts as a "switchboard" between other superheroes in order to coordinate the Justice League's actions. He has sometimes been said to possess 9 different senses, although these are poorly defined and generally ignored by most writers.
His primary ability is shapeshifting which he uses for various effects, such as adopting human appearance, elongating his limbs, growing to immense size, and assuming monstrous forms. Possibly as an aspect of his shape-shifting powers, he can also turn invisible (in most Silver Age stories none of his other powers function while he is invisible), and can alter his solidity so as to become either incredibly dense or (alternately) intangible. J'onn has also demonstrated great regenerative abilities, once able to regenerate himself from only his severed hand but with great strain (due to the loss of matter he found it necessary to incorporate new mass from Martian sand).
Wow, thanks Mr. Wikipedia, without that insightful description of Martian Manhunter, nobody here would know who he was.
