[Speculation] It seems the original inspiration for 2's Netaballerina was supposed to be Bakuro-baba.

Legendary Yokai (hereinafter referred to as L-Yokai) are Yokai that cannot be befriended unless you obtain 8 specific Yokai in the Yo-kai Watch world, but in Yo-kai Watch 1, they have a stronger appearance than existing Yokai. For example, the L-Yokai in Yo-kai Watch 1 are Bushinyan, Shurakoma, Ikemenken, Hanasaka-ji, and Yamabuki-oni, which are evolved forms of Jibanyan, Komasan, Jinmenken, Himojii, and the Oni family, respectively. Except for the last one, they are all selected from D-rank or E-rank Yokai. On the other hand, the new L-Yokai in Yo-kai Watch 2 are Netaballerina, Unchiku-ma, and Yamatan. Netabare and Bakuro seem to have similar elements, but who are the other two? If there were, they might be the following Yokai: ・Meramera Lion ・Murikabe ・Gurerurin ・Wakame-kun ・Jimmy ・Tohohogisu ・Tsuchinoko ・Nagabana ... Perhaps Unchiku-ma was Nagabana, and Yamatan was Tsuchinoko (just a guess).
