Jessica runs the kitchens as head chef of the G-8 Marine base and is married to its commander, Vice Admiral Jonathan. She features only in the anime-exclusive G-8 arc, where a disguised Sanji crosses her path.
Tall, youthful, and striking, Jessica gathers her blond hair into a high bun above dark green eyes. Her working outfit is the usual Marine galley uniform, finished with a cook's hat.
She treats Luffy and Sanji warmly, never suspecting they belong to the Straw Hats. Her cooks respect her, though she bristles whenever they slack or waste time, demanding the same devotion she pours into the job herself. Bossy and proud, she adores both her work and her husband. Sanji's example teaches her to honor every part of an ingredient, and she sets aside her pride as a Marine chef to adopt the recipe he leaves behind.
Sanji, posing as a Marine cook, charms her in the G-8 kitchens, yet the lesson he passes on about never squandering food outlasts his disguise. When the Straw Hats slip free of the base, she marvels at their escape, and Jonathan reveals that uniting G-8 had been his true aim, an outcome the pirates unwittingly helped achieve. She caps the episode by decking Shepherd after he threatens to shut the base down.
