The first human to fall into the Underground, Chara originally gave her life in an attempt for her and Asriel to  break the barrier keeping monsterkind locked beneath Mount Ebott. After you fell into the Underground ages later, her lost spirit became tethered to your SOUL, now acting as your guide to the Underground. Something else you’ve noticed, though, is that her ghostly form seems to be absorbing the calories of your healing items…and now she’s getting fat as hell. Starting weight: 174 lbs.
