Personally, it should be "Amiibo Figure - Samus", so that "Amiibo" shows up first in the search results, not to mention that we can add a (Mario Kart 8 ) or whatever exclusive Amiibo gets released.
EDIT: I'd really like to remain democratic about this sort of thing and just wait it out, but the edits are currently clogging up the updates feed (the system currently only allows for a page of about 20 or so at a time), so I can't let it go on the backburner for now. For now, the naming system will be "Amiibo Figure - [Character Name] (Identifier if necessary)", as it fits the search criteria better.
