I for one, am armless fi all the way. What is your interpretation on how she moves her cloak āarmā things though. I know itās magic, but I wanted to see if you had your own take!
Yes, Iāve thought about this a lot so here it is!
As for Fiās cape, since she wears it so often for so long (sheās been wearing it for literal centuries), a fair amount of her magic is infused into the cape so she can manipulate with better dexterity than any other cloth. Fi also has an emotional attachment to the cape, since it was the first thing Ghirahim ever gave her. She doesnāt know this, but Ghirahim had the cape custom made for her, so that element also helps with how easy it is for Fi to manipulate it. Fi can do things she canāt do with any other cloth like write while wearing the cape, but her handwriting is barely legible.
In terms of material close to Fiās body composition, it works along the lines of an organ transplant. The closer the āgenetic materialā is to Fi, the less likely her body will reject it (except Fiās rejection of prosthetic arms isnāt nearly as bad as irl immune responses since they only just fall off). Fi can manipulate her prosthetic arms far better than her cape, so when it comes to finer movements like writing her handwriting is actually legible. The prosthetic arms require less magic from her in order to move, so for a while Fi kept inputting too much magic into her new arms and kept breaking things. I drew a comic about this.
So yeah there ya go!!
