Super Smash Bros. for Nintendo 3DS / Wii U

Super Smash Bros. for Nintendo 3DS / Wii U, known as Dairantō Smash Brothers for Nintendo 3DS / Wii U (大乱闘スマッシュブラザーズ for Nintendo 3DS / Wii U) in Japan, are two video games announced for the Wii U and Nintendo 3DS during E3 2013. They both act as the fourth entry in the Super Smash Bros. series of fighting games, which features several Nintendo characters. Three newcomers were confirmed, one of them being Mega Man.

Other Mega Man related appearances in the trailer include Rush (who uses Rush Coil), as well as Mega Man wielding the Special Weapons Super Arm, Metal Blade, Crash Bomber, Leaf Shield, Hard Knuckle, Flame Blast, Spark Shock, Slash Claw, and Flame Sword. A Developer Direct video from Nintendo also confirmed the usage of the Top Spin. Also, the Wily Castle from Mega Man 2 appears as a stage, and the Yellow Devil appears as well, possibly hinting a boss within a story mode, a stage hazard (like the Ultimate Chimera from New Pork City), or an Assist Trophy.

Trivia

 * The silhouettes of the Robot Masters in the trailer introducing Mega Man are from their original official artwork.
 * Some text differs between the Japanese and English versions of the trailer to reflect localization differences, such as Clash Man/Clash Bomb becoming Crash Man/Crash Bomber, and Guts Man's serial number DRN 004 becoming DLN 004.
 * It has been noted that when Mega Man uses attacks that require both arms, he vents them afterwards. This is a nod to Super Adventure Rockman where he uses both Mega Busters to finish off Ra Moon while being warned by Dr. Wily that he could overheat himself while doing so.
 * Before Super Smash Bros. Mega Man appeared on the German Club Nintendo comics Super Mario: Die Bescherung and Super Mario: Die Verwandlung.
 * Following the Archie Comics' storyline Worlds Collide, this game will mark Mega Man and Sonic the Hedgehog's first encounter in a video game.
 * In addition, this marks the first time that Mega Man encounters Donkey Kong, Link, Zelda and Pit in a video game since they appeared in Captain N: The Game Master.
 * Incidentally, this will feature the first encounter between Mega Man & Samus Aran who have both appeared in Captain N, though the former appeared only in the cartoon, while the later was only in the comic.
 * The above artwork done by Ryuji Higurashi was done in the same style that was used from the original Mega Man series Japanese box arts.
