Nel with her blade drawn
Nel is the hollowfied Ophelia Lawson. In the year 2319 she was hollowfied by her own father, who rectified himself by saying that for advances, sacrifices were required. But his brother mused that it was simply Anthony's need for experimentation that drove him to do this to his own daughter.
While Nel can change between Ophelia's appearance her true form is that of a fully-grown curvaceous and well-endowed adult with long waving greenish-blue hair. She wears gown that is ripped into a skirt and a top, connected with a single strip across her abdomen.
Nel, is largley different from Ophelia, she is much more mature, composed, logical, sophisticated, and intelligent than her "human" form. Unlike many of the Hollows, Nel is somewhat pacifistic, and according to her "peers", has despised engaging in combat, unless it involves self-defense and protecting those dear to her heart.
She refuses to finish off weaker or injured opponents, and will stop fighting them once they've been disabled or incapacitated. As witnessed during her numerous fights with Ianto, Nel's shown to be relatively calm and silent when fighting, preferring to speak only when spoken to, a rather uncommon trait among most Hollows. She is even shown to enjoy reading, usually seen reading a book after her missions. Nel's also shown to be a loyal, respectful, and trustworthy warrior, who will diligently follow the orders of her commander, provided said commander has proven his worth. She's also knowledgeable, analytical, easygoing, fairly compassionate (usually towards her friends), humorous in her own right, and exhibits a cheerful, energetic demeanor when off-duty.
