The number five. I've always associated numbers with colors, genders, and personalities, and to me five is a cocky guy, probably because of how commonly it is used. Plus the color I match it with is orange, my least favorite color.
1 is the arrogant kung-fu guy and the leader. Because he's always the first, he believes the world revolves around him. Despite his arrogant tendency, he trusts 2 and truly despises 7.
2 is the Dragon, the second in command. He's the silent one who's always behind 1, acting as a consulter. He's secretly in cahoots with four to overthrow 1.
3 is the brute. Not very smart, but very strong. The kind of people that would crush you before asking questions. Forms part of a trio with 6 and 9, he's the strength of the group.
4 is the dumb and freaky girl... or so it seems. It's a case of obfuscating stupidity, she blabbers about death all the time and looks like a moron, but in reality she's a mastermind and every other number is just a piece in her chessboard.
5 is the greedy perfectionist. He's always dressed elegantly and is the one in charge of the financial status of the group. Everything must be PERFECT for him. Doesn't get along with anyone, especially 7.
6 is the laid-back girl. She'd rather just sit back and enjoy the day while everyone else does the work. Despite this, she's actually very agile and knows how to use her fingers. Forms a trio with 3 and 9, she's the speed of the group.
7 is the serious and bitter one. He despises every other number. Maybe because he doesn't feel as unique as the rest?
8 is the lovable fat and lazy guy. You will see him joyfully enjoying a snack almost every minute. He loves the taste of food. Only one in the group that can cheer up 7. Gets along with 6.
9 is the full-of-himself glasses guy. He may not be as agile or strong as the rest, but he loves to show off his intellectual skills whenever he can. He's the brain of the trio with 3 and 6.
0 is a complete enigma. It never says anything, it never speaks. No one knows what it was like before being banished by the other numbers... but it is said that it's always there... observing everyone.
