i never got to talk about it much besides with this one person,
Eats-The-Sandals its like when he was a kid his parents sometimes forgot to feed him so he would chew on sandals because he was hungry and the only thing around was sandals. eventually they started giving him sandals to chew on because he started only wanting to chew on those instead of regular food, and even starting to eat the sandals (which was not very good for him). at that point they hadnt decided on a permanent name for him yet as he had not distinguished himself in any way (this was when he was a young kid) so they decided to name him Eats-The-Sandals. as he grew up he returned to eating more normal food so he could survive but he never stopped wanting to chew on sandals whenever he saw any, and he grew up with the name so it stuck and he never wanted to change it to anything else. even now when he sees sandals he will take them and store them in his bag for later sometimes you will find his bag full of random sandals for seemingly no reason.
its kind of hard to describe his personality especially because i havent played the character for a while.. it was like somewhat rebellious sometimes being chaotic while still acting somewhat normal most of the time, and he was very confident in his abilities when he was doing stuff he knew how to do. was also not afraid to interact with random people or show up to the front of security or the bridge and talk to them without reflecting the formal chain of command in the way he talked.
this was just one of my characters but its the one with the most backstory, i will prob end up making more once i get other ideas for characters
