More like stone katana. It’s not cracked, it’s pattern of rock (maybe marble, i’m not good at rocks as Maud, hehe)

Her mouth covered on purpose, I’ve wanted exactly covering her muzzle with the sword to make a little “mystery”.

Yeah, Limestone Pie and Raphael are hot-headed, Pinkie Pie and Michelangelo are hyperactive and carefree, Maud and Leonardo are more cold and pragmatic. Limestone have same trait as Leo - leadership, but no one other match Raphael as good as she does. So the last one will be Marble as Donatello, she is reclusive and Donnie have something like that, but tbh Marble isn’t matching with any turtle, Maud is matching Donnie better, but Marble can’t be Leo or leader, so i chosen what I’ve chosen, hehe.

IDK why Leo isn’t an engineer and Donnie does, maybe creators was choosing with some other criteria.

Crystal Katana?
Cracked because she actually used it to “lightly tap” a few targets?

Is her mouth covered because you had difficulty getting a neutral enough expression?

My TMNT lore is pretty rusty(a). Is their any particular reason you paired the Pie Sisters to the specific Turtles you did?
(a) It doesn’t help that they named the one who does machines ANYTHING other than Leonardo, whose namesake was a guy with engineering ideas(b)… Donatello was it?
(b) Many of which wouldn’t have worked if he had actually made them, but were still in the GENERALLY correct direction.
