Mega Man (ロックマン, Rockman), also referred to as Mega (ロック, Rock), is a character from the eponymous Mega Man series by Capcom. He was announced as a playable character for Super Smash Bros. 4 in the E3 2013 Nintendo Direct.
Mega Man is a highly advanced robot with a near-human personality created by Dr. Thomas Light. In the year 20XX, Dr. Light and Dr. Albert Wily worked together to create robots with unprecedented artificial intelligence that could be used to supervise other less advanced robots. The prototype of these robots was known as Proto Man (called Blues in Japan), but having a free-spirited personality, and fearing being tampered with to fix an unstable core, he ran away. Dr. Light theorized that Proto Man ran away because he desired a companion, so he next designed two robots: Rock, designed as a lab assistant, and Roll, designed for house work. Based on these successes, Light and Wily then built six Robot Masters: Cut Man, Guts Man, Ice Man, Bomb Man, Fire Man, and Elec Man. However, Dr. Wily grew jealous of the recognition Light received for their work. Wily began his designs for world conquest and stole the Robot Masters. Seeing Rock and Roll as useless, Wily left them behind, inadvertently creating his ultimate undoing, as Rock would volunteer to be converted into a fighting robot. As Mega Man, he would thwart Wily's plans time and time again.
As Mega Man, Rock possesses the Mega Buster, a weapon that converts his hands into a powerful energy cannon. From Mega Man 4 onwards until Mega Man 9, the Buster can be charged to release a Charge Shot. Beginning in Mega Man 3 and again continuing until Mega Man 9, he also possesses the ability to slide along the ground. Mega Man's most impressive power, however, is his Variable Weapons System, which allows him to copy the powers of Robot Masters he defeats. These weapons then prove useful for taking out smaller enemies or another Robot Master weak to that particular weapon in a rock-paper-scissor style system.
Mega Man is consistently shown to have a strong sense of justice, highly valuing peace. These values were what led him to be converted into a fighting robot in the first place, and the games stress Mega Man's never-ending fight to ensure peace. However, Mega Man has his breaking point, as seen in Mega Man 7, where he nearly kills Dr. Wily, tired of his repeated attempts at world domination.
Mega Man has a large group of allies and companions who help him on his adventures. Dr. Light and Roll often serve in an advisory capacity, while other robots help him more directly. Rush, Mega Man's robotic dog, serves as transportation for him by transforming into tools such as a spring or jet. Proto Man often aids his younger brother after a stint of working for Dr. Wily in Mega Man 3. Other less advanced robot helpers include Eddie, who distributes items, Beat, who serves a variety of functions, and Auto, another assistant of Dr. Light's.

Mega Man appears as a playable character. He uses copied special weapons from Robot Masters that he fought throughout the original series. Thus, his playstyle is more focused on weapons and range rather than physical combat, in a similar vein to Snake.
Mega Man is placed 27th on the tier list, sitting within the C tier. With his arsenal of projectiles at his disposal, Mega Man is granted a strong spacing game. Some of these projectiles also have useful utility, with Metal Blade being able to be thrown in all 8 directions, Crash Bomber being ideal for pressuring shields, and up aerial having the potential to KO opponents easily at the top blast line. Mega Man also possesses some highly powerful finishers, such as up tilt, down smash, and down aerial, and he also has great air mobility due to his good air speed and fast air acceleration. However, being dependent on projectiles leaves Mega Man at a disadvantage against opponents with reflectors, and his quick falling speed and high weight give him a vulnerability to vertical hits. Overall, Mega Man's high learning curve has not allowed for much tournament representation, but his results have been impressive thanks to the efforts of players such as ScAtt and Kamemushi.
