SUPER SMASH BROS. SERIES:

The vast majority of currently available amiibo figures are based upon character designs from Super Smash Bros. for Wii U & 3DS.
The Super Smash Bros. amiibo figures are posed as each character appears on the in-game character select screen and in their Classic Mode trophies. Nintendo has confirmed production of an amiibo figure for every character from the Super Smash Bros. roster which, including the DLC characters, is over 50 different figures!
It remains to be seen if Nintendo will release variant figures for characters that have alternate character models such as the Male Wii Fit Trainer, Female Villager, Alph, Female Robin, Classic Wario, and all seven Koopalings, but here's hoping!

PRE-AMIIBO:
