Dr. Mario (USBIV)

Dr. Mario is an unlockable character in Ultra Smash Bros. IV and makes his third return in the series since Melee. He was confirmed during the Famicom Smash Week, where some of the characters appears in Nintendo Entertainment System that they have only one or at least 2 games, or games that they are hardly to remember, alongside with R.O.B., the Ice Climbers, Little Mac, Duck Hunt, and the newcomers Excitebike Rider and King Hippo. In his own titular series, Dr. Mario, Mario decided to turn into a doctor and take away of the viruses in his puzzle games. In this game, he uses only his Multivitamins that he uses in his own games. Dr. Luigi make also his appearance in this game.
Dr. Mario is known to be as a half semi-clone of Mario. He's a lot stronger based on knockback and percentage. But his mobility overall is much weaker. His only difference comparing movesets, is that Dr. Mario maintains his Dr. Tornado while Mario not (F.L.U.D.D.), closely similar to Luigi's Cyclone.
Dr. Mario share the same voiceclips of Mario, voiced by Charles Marinet, with less vocailty that Mario has in his moves.
Dr. Mario ranks the 46th place of the 103rd in the tier list, putting him at the top of the high tier placement (B) behind Jigglypuff and after Black Mage, making him a decent high tier character. This is a significant turnback situation when Dr. Mario was a solid mid-tier in Melee and a strong rise unlike his low tier position in Smash 4.
