Immortal for some reason, is mistaken for a boy more often then she's like. Cyber is actually mistaken for a girl, in FFTW rp by my good pal Justice_The_Soul, both Mephiles and Iblis mistook his gender as a female.

Mephiles: *to Metal* I didn't know you had a sister.

Metal: *shocked and has no reaction*

Shard: He's not a girl...

Cyber: *heard Shard correcting Mephiles* WHAT THE HELL???

When Cyber and Iblis will finally meet in person.

Iblis: So, you, the remaining sister out of the trio of siblings--

Cyber: DID YOU JUST ASSUME MY GENDER???

Iblis: ...

Metal: ...

End: ...

Iblis: Oh, he's a boy?

Shard: Yes he is.

Iblis: Okay, I have to admit, you're pretty freaking feminine.

*everyone agrees*

Cyber: *offended noises*

(In the rp I will add greater detail for the scenes.)
