>>20632434I believe it's 'cuz it's also partially based on a Kendo practitioner.
First of all, check out that "skirt" - it resembles a part of clothing that is worn under Kendo Bogu (armour) called "Hakama," which is a traditional type of Japanese clothing. Mawile also has black hands that resemble the black gloves that Kendo practioners wear, called kate.
Secondly, Mawile gets Swords Dance, while the tale of the Futakuchi-Onna has no reference to her being a swordsman of any sort. Mawile also gets Astonish and Screech, which could reference a Kendo technique that involves loud yelling when attacking to make themselves appear more threatening to the opponent or to psyche them out, as well as to "build up the fighting spirit." Also explains why it'd be Steel instead of Dark or something, and also why it'd have Intimidate as an ability, as well as Hyper Cutter (so others can't Intimidate it) and Sheer Force.
Thirdly, Froslass is based on the somewhat similar Yuuki-Onna tale. Both of these creatures are women. If Mawile was based solely on the Futakuchi-Onna, why can Mawile be male? After all, Froslass is f.emale-only, right?
Of course, I could just totally be waffling. This is just what I think.
(fuck the goodrafag btw)
