Amiibo Dr Mario
In the 1990 Dr. Mario game, Mario threw on a white coat and decided to take a shot at that whole "medicine" thing. Dr. Mario destroys killer viruses with his amazing vitamin capsules and spends day and night in his laboratory working on new miracle cures. Somehow he's managed to keep up with all the new viruses that have arisen over the years.
Dr Mario works with games including Super Smash Bros. on the Wii U and the 3DS, plus Hyrule Warriors, Captain Toad and Mario Party 10 on the Wii U.
