Okay, I know I'm late(like, REALLY late), but I saw this in the General RP Forums and thought I'd give it a shot. And yes, I know more about Undertale now than the first time. Could I be the Soul of Bravery?
Name: Roxie
Sex: Female
Soul: Bravery(Orange)
Backstory: Roxie wasn't always brave. When she was seven, her pregnant mother was killed in an accident. Upon their deaths, Roxie felt she needed to be brave for both of them. She found a passion for BMX, dirtbiking, and boxing, and six years later took up a supposedly impossible challenge: riding her dirtbike over Mount Ebott. Needless to say, Roxie didn't make it. She caught her tire on a rock and tumbled down the hole. Toriel found her and did the Goat Mom thing. Eventually, Roxie was faced with the choice to stay or leave. It was a hard choice, considering Toriel was the closest thing to a mother she'd had for six years, but she left. Upon leaving, Roxie made an unlikely friend: Napstablook. The duo became friends due to their shared love for music. One day, Roxie went to the Hotlands to do a big stunt on a landform there, but fell into the lava. Only her legs were submerged, and she was able to drag herself out. However, she was incredibly weak and dying fast from her wounds, so it was easy for the Royal Guard member to finish her off when he found her.
Cause of death: burns and a sword in her back.
Monster connection: Napstablook.
