B-Medals (Japanese: Ｂメダル Bī Medaru) are toy-exclusive Yo-kai Medals introduced following the release of the Yo-kai Watch Blasters games, with the design of the Yo-kai Medals serving as the standard Medal designs in-game. The B Medals in the west are unofficially known as B Yo-Motion 2X Medals. These Medals work with the DX Yo-kai Watch Model U and Dream Model. When B Medals are inserted into either DX Yo-kai Watch models, it performs the normal soundbytes, but it also adds a musical motif, followed by announcing that Yo-kai's role as a Blaster.
B Medals are black (except for the Legendaries), with their artwork featuring their Yo-kai doing some sort of action, with the name being written in calligraphic font.
Similar to the Z and U Yo-kai Medals, B Medals feature a distinctive marking in the upper right corner of 4 specific kanji, which vary depending on what that Yo-kai's role is as a Blaster: Attack (Japanese: 攻 Kō) for Fighters, Heal (Japanese: 治 Ji) for Healers, Odd (Japanese: 奇 Ki) for Rangers, and Protect (Japanese: 守 Shū) for Tanks. The kanji, much like the names, are written in a calligraphic font. The role of a Yo-kai as a Blaster also influences the inner frame's color: Red for Fighters, Green for Healers, Purple for Rangers, and Dark Blue for Tanks.
There are also B Medals that depict Boss Yo-kai. The B Medals that have Boss Yo-kai on them are known as Boss Medals (Japanese: ボスメダル Bosu Medaru). When inserted into the DX Yo-kai Watch Model U toy, it will play a ominous electric guitar chord.
There are 205 B Medals in Total.
It is confirmed that the QR codes of the JP B Medals are 300% compatible with the international version of Yo-kai Watch Blasters.
