Powers and abilities
Martian Manhunter possesses a wide variety of superhuman powers, many of which are virtually identical to those of Superman, including superhuman strength, speed, durability, flight and "Martian vision" (a term designating both the ability to see through solid objects and the ability to generate optic heat beams). During the 90s, it was stated that J'onn also possesses a form of telekinesis, which is the source of his flight and destructive "Martian vision" beams. Early appearances of the character showed him as able to breathe underwater. The last time he displayed this power was when he encountered Zauriel in the sea of San Francisco in JLA #6.
The Martian Manhunter also possesses the power of shapeshifting, which he employs for various effects (e.g., adopting human or monstrous appearance, elongating his limbs, growing to immense size). He can also render himself invisible, and is able to become intangible so as to pass harmlessly through solid objects. He can also change the genetic makeup of his body becoming made up of materials like steel or stone.
In addition to these abilities, J'onn is a powerful telepath, capable of both perceiving the thoughts of others and of projecting his own thoughts. He often acts as a "switchboard" between minds in order to coordinate the Justice League's actions. He has also demonstrated regenerative abilities, once able to regenerate himself from only his severed hand but with great strain (due to the loss of mass he found it necessary to incorporate new matter from Martian sand). The Manhunter has sometimes been said to possess nine different senses, although these additional senses are poorly defined and generally ignored by most writers.
Aside from his superhuman abilities, he is also a cunning and logical detective. As Batman mentions in his file, that "in many ways, Martian Manhunter is like an amalgam of Superman and the Dark Knight himself
Abilities
Piccolo has shown many abilities throughout Dragon Ball. Being a Namekian, Piccolo can regenerate lost limbs of his body, as long as his head is still intact. Piccolo also has the ability to conjure various objects, such as clothing.
Like many other characters in Dragon Ball, Piccolo has the ability of flight. He also possesses an attack called the Bakurikimaha ("Destructive Wave" in the English dub), which is fired with one hand being supported by the other. One of Piccolo's most powerful attacks is the Makankosappo, ("Special Beam Cannon" in the English dub) an attack that is expelled from Piccolo's index and middle fingers. Unlike most energy-based attacks in Dragon Ball, the potent Makankosappo pierces its targets like a drill rather than enveloping them or exploding on contact. Piccolo's ultimate attack in the video games he has appeared in is called "Hellzone Grenade", which involves firing off many orbs of energy that float around the opponent. Piccolo then squeezes his hand to make all the orbs converge onto the opponent, exploding on contact. Piccolo also possesses the ability of "Scatter Shot" in which he fires many different chi blasts shot from one hand at the same time. Piccolo is also seen possessing an attack called the Masenko or Demon Wave, which Piccolo teaches to his pupil Gohan. Another move Piccolo is seen to have is the Gekiretsu Kodan, ("Light Grenade" in the English dub) which is conjured by putting his hands on his chest, gathering energy and then releasing it outwards. One of Piccolo's less frequently used techniques is the ability to fire energy rays from his eyes, which he uses against Goku in the 23rd Martial Arts Tournament and again when he trains Gohan in the Saiyan Saga.
Piccolo can also perform the "Namekian Fusion" which he first does with Nail on the distant Planet Namek to confront Frieza, and then with Kami at the Lookout to stop Cell.
