Though Capcom owns the rights to all Mega Man games and has been responsible for the development of all of his console titles, it has in the past licensed the Mega Man character to other companies for PC releases. Mega Man and Mega Man III (with no relation to the NES games of the same name) were developed by the US-based Hi-Tech Expressions, the Mega Man game published on the Game Gear by Sega, and Rockman Strategy was developed and released exclusively in China by AcerTWP. Neither title has since been regarded by Capcom as an official Mega Man series game.
MegaMan.EXE and Zero both appear as bonus playable characters in the fighting game Onimusha Blade Warriors, while a different version of Mega Man, based on his appearance on the American box art of the first game, appears as a playable fighter in the PlayStation 3 and PlayStation Vita versions of Street Fighter X Tekken. Mega Man Volnutt and Roll also make an appearance in Tatsunoko vs. Capcom: Ultimate All-Stars, with Zero added to the U.S. version. In 2013, Mega Man is a playable character in Super Smash Bros. for Nintendo 3DS and Wii U and it's sequel, Super Smash Bros. Ultimate. An amiibo based on his appearance was confirmed on November 11, and can be utilized in Super Smash Bros. as well as Mario Kart 8 where it can be scanned to unlock a costume for the player's Mii based on Mega Man's. In Super Mario Maker, the player can unlock a Mega Man costume by scanning the character's amiibo.
The rescued princess journeys alongside Kirby until she is attacked and turned into a trophy by Bowser, who uses a swarm of Shadow Bugs to create a clone of the princess. If the princess is Zelda, the clone tries to attack Link and Yoshi, but is intercepted and destroyed by Mario and Kid Icarus hero Pit. Link notices the battle just in time to see what appears to be Zelda's trophy dissolve into nothing, and attacks Mario and Pit in a rage.
Three main installments, as well as one online game, were published for the PlayStation 2 (PS2). Final Fantasy X (2001) introduced full 3D areas and voice acting to the series, and was the first to spawn a direct video game sequel (Final Fantasy X-2, published in 2003). The first massively multiplayer online role-playing game (MMORPG) in the series, Final Fantasy XI, was released on the PS2 and PC in 2002, and later on the Xbox 360. It introduced real-time battles instead of random encounters. Final Fantasy XII, published in 2006, also includes real-time battles in large, interconnected playfields. The game is also the first in the main series to utilize a world used in a previous game, namely the land of Ivalice, which had previously featured in Final Fantasy Tactics and Vagrant Story.
