She's a 14-year-old girl immune to the Cordyceps. She can't get infected or get other people infected, but she also can't make other people immune. She has auburn hair tied into a ponytail with side bangs she pushes out of her face a lot. She only wears cargo pants or jeans with a long-sleeved shirt underneath her t-shirts or flannels. She's fiery and optimistic. She's outgoing, caring, and constantly trying to make friends. Ellie lives in the garage in Joel's back yard instead of his house.
