Kelli Potter is Harry Potter's twin. In most stories with this plot they are equally famous, but Harry is the only famous one. HE is the boy who lived. HE stopped the darkest wizard known to man. Kelli was sitting in the same room as Harry that same night their parents were slaughtered by Voldemort; however, Voldemort then turned his wand on Harry first. His powers were gone before he could even look to the second child. This story takes place in 5th year for them both. Jk Rowling owns all characters except my own added ones not displayed in the movies or books.
