Canon Mangle (Female) is better than Headcanon Mangle (Male).
I am gonna end this fucking gender war once and for all.
Mangle at first was said to be a yes for a joke and that she not yet had a specific gender.
But later on when Ultimate Custom Night came out, her gender was revealed to be female due to the voice. Not the texts about how she gets in the vent and such.
So, Mangle is not actually a male. That was a joke all along.
Mangle is a female.
And that is that.
No gender wars in the comments or there will be consequences.
