Antonia is a papergirl who lives in Ninjago City.
Antonia has red hair with some black streaks piled on top of her head, often concealed by a helmet when she's riding her bike.
Antonia debuted in "The News Never Sleeps", helping new paperboy Lil' Nelson learn the ropes. Used to the constant turmoil in Ninjago City, she rides almost carelessly through attacking fire snakes and expresses total confidence in Samurai X's ability to deal with them. Later, after she and Nelson find Clutch Powers and learn that the Ninja are in danger, she reluctantly agrees to accompany Nelson to the Monastery of Spinjitzu to alert Master Wu. Her skill is demonstrated as she jumps a bridge that has crumbled, and with her encouragement Nelson is able to follow her lead. The pair then deliver their news to Wu before heading back to the city.
