Nell has blonde hair with a red hair clip on the left side and and a white one on the other, blue eyes and light-colored skin. In "A Journey's End?", her attire includes a green and gray competitor's uniform, a brown chain necklace, and a single gray and green part of her long pants on her left foot. She also has a reddish-brown, greenish-brown (Aqua), and a white anklet on her right foot. In "Hero in Residence", her appearance is similar to what she looked like in Episode 8, but her sleeves are gone. She now wears a set of bluish-green shorts.
Nell appears to be a kind individual and is always polite, even to her Competitors. She is quite good-natured, as shown when even after Jesse attacked her once/twice she is still quite friendly towards him/her.

Death (Re-spawned, Determinant)
- Emily (Determinant)
On the vine wall after Gladiator Junction in the Lava Race, if Jesse chooses to beat Emily or do nothing, Nell will fall in lava and die, but will later respawn.
- If Jesse decides to be silent during his/her motivational speech, Nell will say, "But that stare of yours is filling me with... determination." This might have been an Undertale reference.
