Amiibo

Amiibo (アミーボ) is Nintendo's wireless communications and storage protocol, for use between compatible toys and the Nintendo 3DS and Wii U gaming platforms. It was launched in November 2014 in the form of system software updates and a series of amiibo-enabled figurines, colloquially abbreviated as "amiibo figurines" or simply "amiibo". The platform was preannounced to potentially accommodate any form of toy, specifically including general plans for future card games. These toys use near field communication (NFC) to interact with supported video game software, potentially allowing data to be transferred in and out of games and across multiple platforms.

Mechanics
The characters spawned by amiibo have been compared to CPUs, as they both use artificial intelligence. In Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate, players can train the figurines to be able to learn new fighting tactics. The amiibo character will adapt to the player's play-style, learning how to play against the player. For example, if a player always taunt after landing a KO, the amiibo can learn to do the same; or if one always try to Meteor Smash opponents using risky tactics, the amiibo will learn to do the same. In order words, the better the player, the better the amiibo will become.

They are also programmed to detect and use items depending on the player's usage patterns. For example, if one always play matches without items and introduce items to them, they will be "confused" and "unaware" on how to use them.

The amiibo will use the same moveset, and have the same stats as the character they are modeled after. However, players are able to change their stats by "feeding" them items. This will change their base stats depending on what the piece of equipment is. The maximum level an amiibo can reach is 50.

Amiibo's interaction with a game may be either "Read/Write" or "Read Only". "Read/Write" will save certain game data directly to the amiibo figure; however, each amiibo can only hold data from one such game at time. If using the same amiibo, new data from another "Read/Write" game can only be saved by deleting the data from the previous "Read/Write" game. Super Smash Bros. for Nintendo 3DS and Wii U is a "Read/Write" game. "Read Only" games scan the amiibo to unlock additional in-game content and features, but do not save data to them. They can therefore be used repeatedly and on multiple "Read Only" games without affecting the amiibo's saved data. Mario Kart 8 is a "Read Only" game. Mario Party 10 has both "Read/Write" and "Read Only" capability, depending on which amiibo are used.

Mega Man
A Mega Man amiibo figure was released in February 2015 as part of the third wave of Super Smash Bros. for Nintendo 3DS and Wii U amiibo figures. The Collector's Edition from the 3DS version of Mega Man Legacy Collection included a golden colored Mega Man amiibo. A new Mega Man amiibo was released alongside Mega Man 11. Ten golden colored Mega Man amiibos for Mega Man 11 where given away in a contest held in Japan by Capcom in 2018.

The Mega Man amiibo is also compatible with the following games:
 * Mega Man Legacy Collection - Unlocks new challenges.
 * Mario Kart 8 - A Mega Man themed costume becomes available for Mii characters.
 * Yoshi's Woolly World - Unlocks a Mega Man themed skin for Yoshi.
 * Super Mario Maker - A Mega Man skin becomes available for the small Mario. The Mega Man skin in Super Mario Maker is a scaled down version of his NES sprites.
 * Amiibo Tap: Unlock a demo for a random Virtual Console game.
 * Mega Man Legacy Collection 2 - Unlocks new challenges.
 * Mega Man 11 - Gives the player a free Energy Tank if used once a day.
