A character wishes to become a knight but cannot, either because of gender, social class, or some other limitation. Thus they either lie about being a knight, or set out to become one in secret, often using a helmet to conceal their true identity. The character's motivation for becoming a knight can vary: sometimes they seek to prove themselves, sometimes they wish to escape another fate, or perhaps they aspires to the ideal and romance of becoming a Knight in Shining Armor or Knight Errant. Often will be known by a descriptive title like "Black Knight" or similar, or may be using a suitably noble sounding alias.
