|Full Name||Jessica Nietzsche|
|Born||August 5, 1999|
|Voice Actor||Jessica Nigri|
In season one, Jessica is sixteen. For the first half of season two, Jessca is seventeen, and is eightteen during the second half.
Jessica has light and bright blonde, almost white hair, which parts on the left towards the right and is about chest-length. She has big hazel eyes. She is a little shorter than Alan and a little taller than Alexis. She usually wears a navy t-shirt, black pants, black converse, and a green hoodie. Sometimes she'll wear a hat and wear the hood at the same time.
Her Tacopolis uniform consists of her usual pants and shoes, but with an orange polo with a red colar and stripe on the right side, an orange hat with a red bill, and a nametag on the left side of her shirt.
Her picture in her template consists of her wearing a blue Deadpool uniform, with the Deadpool face on grenades and belt being replaced with blue Simplicitrix symbols.
Jessica so far has shown to be very kind-hearted and positive minded, having told Alan she thinks he's a "good weird" and even becoming overjoyed when he and Alexis said they'd vouch for her if she was questioned by her boss at Tacopolis. She also seems to be rather enthusiastic as she was confident that Alan and Alexis would get jobs at Tacopolis.
