He has blue eyes, brown hair, fair skin and wears a yellow T-shirt with white stripes, and blue jins.
In the December 23 minigame, he is seen in a car with him and his family inside, waiting for his dad, but they are later being car crashed by Alison.
In the December 24 minigame, Charles is seen celebrating Christmas with his dad, while he is playing with his toys, Gron gives him a present: a fedora.
In an December 25 minigame, you take control Charles after Christmas, alone in your house. Gron leaved a note, wich the player can read by clicking space, that reads "Dear Charles, daddy won't be home for a very long time... I did some things that I can't exactly explain to you since you are too young to understand. I'm sorry my little one, I will be back... soon... - Your daddy". Later you must walk to an unopened gift, when you touch it, the minigame ends.
In the December 28 flashback minigame, were you control Gron, Charles is again seen in his house, hanged with a noose. The player/Gron can look at a note wrotten by Charles with blood that reads: I'M SORRY DADDY. After a while, Gron will start to cry at him and the minigame will end.
In The past... minigame, he is seen crying with other kids who are being entertained in Frankburt's Pizza. The player needs to walk to a door to exit the minigame. While you walk, you'll see his dad in his office, his dad watches over him, before shutting the blinds over his window. After entering the door, the minigame ends.
In the abandoned... minigame, you'll again take control of him, in an abandoned location, where you'll see parts of animatronics, and his dad inside of Torture Golden Lockjaw. After touching Torture Golden Lockjaw, the minigame ends.
In the The horrrible truth... minigame, again, you'll take control of him, in Fredbear's Family Diner. While walking to the Show Stage, you'll see that the screen kepts flashing the word IT'S ME. When the player gets to the Show Stage area, Gron will appear entertaining children. Later, Charles will put an Torture Golden Lockjaw head in Gron's, while gron cries, and will start to bleed. The minigame ends with an Torture Golden Lockjaw jumpscare.
Gron couldn't bare to have his child see his own father in such a horrible state of condition. He didn't want his child to see his own father in so much pain, physically and mentally. So Gron then wrote a little note for his son to read and it's said: "Dear Charles, daddy won't be home for a very long time... I did some things that I can't exactly explain to you since you are too young to understand. I'm sorry my little one, I will be back... soon... - Your daddy". The oldest son Charles, didn't know what to do alone. He only knew so much, but he wasn't ready for this. He then stood paralyzed for a few seconds and heard a voice in his head. Charles heard whispering in his head that had a familiar voice, that almost sounded like his mother. He slowly looked towards the last unopened gift box, slowly opened it, and the whispers grew louder and louder. Eventually later that day Charles committed suicide by hanging himself with a noose.
