Mega Man 2 (ロックマン 2: Dr.ワイリーの謎, Rockman 2: Mystery of Dr. Wily) is a 1988 platforming game published by Capcom for the Nintendo Entertainment System and the second game in the Mega Man series.
The game improved on many elements from the original Mega Man game such as graphics, music, and modifications to make the difficulty balance more manageable such as the introduction of E-Tanks, which restore health, and allowing damage invincibility to temporarily protect Mega Man from spikes. The game also introduced transportation items that would later be revived throughout the series as Rush.
The game's story sees Mega Man continuing his fight against Dr. Wily as he introduces eight Robot Masters of his own. Once Mega Man defeats all eight Robot Masters, he infiltrates Dr. Wily's castle and confronts the doctor himself.
In the Super Smash Bros. series
The game is featured as a Masterpiece in Super Smash Bros. for Wii U, in addition to being the origin of many songs appearing in both versions of SSBWU/3DS. Additionally, many of Mega Man's moves originated in Mega Man 2, including Metal Blade, Crash Bomber, and Leaf Shield. The design of Wily Castle comes from Dr. Wily's Castle in this game.
