Katie Bell is the star chaser of the Gryffindor house Quidditch team. Scouted by Oliver Wood in her 3rd year at Hogwarts the current 6th year student is now a valuable player in the side. Teamed up with her best friends Alicia Spinnet and Angelina Johnson the 3 friends have scored plenty for the gryffindor side.

Born Katlyn Felicity Bell to parents Kirian and Kathleen Bell, Katie is the youngest of 3 siblings. Her older brothers Kent and Keith are both graduates of Hogwarts. She grew up in a loving and careing household and has not had much cause to complain besides the usual sibling rivarly and bullying by her 2 older brothers. Being the only girl Katie grew up a little more rough and tumble than ladylike. The whole family being mad on quidditch, it only seemed natural that Katie would be good at the game and end up in the house team.

As a student Katie is diligent and hardworking although not very remarkable in any subject she works hard and scores fairly good grades in school. She is currently holding 10 O.W.Ls and is working hard towards her N.E.W.Ts

Katie has never shown any great interest in any of the boys in school, prefering to keep her mind focus on school work and quidditch which is why it was a great surprise to all of her friends when Katie started dating Ravenclaw chaser Ryan Jorin. Not only was this surpriseing that she was seeing him but it was also known that Katie was fiercely competitive in quidditch which would ordinarily make her dating a rival team's player even more unlikely. Yet Katie is very much taken with Ryan though she would never admit to being in love. Her brothers tease her constantly about it through their letters but secretly they are very happy for their sister and a general invitation to visit the family during the holidays has been already issued to Ryan.

Katie is also part of a group known as the Corona Magicus. A group of friends joined by the amulets that they wear and the adventures that they share.
