((These are my versions of foxy, here is how they behave, their height, sanity, and small details))
All of the Foxy's have bright yellow/gold eyes and the nightmare tongue.
This version of Foxy is mainly used for FNAF 1 & 2 ((seeing as the 4th game is somewhat before her animatronic being made)). Being the tallest out of the animatronics, she stands at exactly 7ft. She is somewhat normal despite being dead, and doesn't really care for trying to scare anyone unless they deserve it. She is like a guardian or a big sister to the other animatronics even though they don't really need her so she usually stays in the cove. She tends to have her mind in the gutter like most pirates but doesn't act on her thoughts. She's easily embarrassed and tries to keep herself from being caught off guard. At this point of her life, she is very content with her life at the pizzeria.
Withered Foxy is used mainly for FNAF 3. Being out of order for so long, she's been put into a state of disrepair and has had most of her parts scrapped to save time and money on repairing her. Her stature has been brought down to an adorable height of 5'6". Being as old as she is, she tends to squeak when she moves and also has a cracked voice which fluctuates in and out of white noise. Her sanity over the years has dropped to the point where she suffers from paranoia and sometimes hallucinations. With the cove missing from this location, she tends to spend her time hiding in any of the storage rooms excluding the ones that were boarded up simply because she is terrified by who is still locked inside them.
Due to no particular use, Nightmare Foxy can show up in any of the games. At a staggering 8'6", she is the absolute tallest in static height and is very monstrous in nature. Like animals in the wild, she likes to play with anyone she considers to be her prey and she only hunts for pure sport. Her eye patch has been permanently removed to show she is fully aggressive and will attack. Seeing as she is no longer sane, she confuses friend with food and will attack anyone dumb enough to come near her. Her jaw has been nearly torn off from one of her previous attacks and fears no man. Her actions are very erratic and she should be considered completely dangerous.
Just like Nightmare Foxy, Shadow Foxy can show up at any time. Being the remnant of what used to be Foxy, she cannot speak but still shows some emotion. At her normal height she is at a perfect 5ft. Being a shadow, she can stretch and shrink as much as she likes and gets a kick out of scaring the guards. Any signs of sanity are completely gone for she always appears to be crying while laughing at the same time. Her behavior, like Nightmare Foxy, tends to be very erratic and out of control. She's not dangerous.
