The Sailor Rainbow Series/YMMV


 * Draco in Leather Pants -- Draco, appropriately enough.
 * Shipping -- Fiore/Lydia, Seamus/Lydia, Harry/Serena, Draco/Raye, Lucky/Professor MacGonagall
 * Tsundere Sue -- Being Oireish and having red hair, Lydia is known for her easily provoked temper, unless she's around Fiore. (She gets it from her mother, who was ) But that doesn't stop the fact that just wearing a "Kiss Me, I'm Irish" shirt will cause a crowd of boys to gather around her, hoping for a kiss. See the rest of this list for more of her Mary Sueish qualities.
 * She is also a Black Hole Sue (see above), though this is toned down in the latter stories.
