Morticia, Roxanne Ritchi, Marianne, Stella, Thea Stilton, and Rarity are not seductresses. I watched these and never saw any kind of seduction. Rarity is the closest, but never actually seduced a man, just flirted with them.
Also, Lena De Spell is a little girl. That's too young to be seducing men, and she never even tries. She's not feminine she's a tomboy.
Stop adding females to the Seductress category just because you think they're pretty.
