You were a great warrior from the royal guard, very strong and skilled as a result of your training with Undyne. One day, you were walking in Waterfall, when you notice something moving in the high purple grass. You wondered what was that. You came closer, a human leaves the grass, he had a green sweater with yellow stripes, short brown hair, green shorts and brown shoes, you already knew this human, Chara, the worst of everybody's enemy. Undyne talked about him with you, she said for you to stay away from him, but you won't, because you're brave and more determinated than Frisk, you NEVER surrendered and you never will.
You follow the merciless murder, if he hurts someone else, at least you will stop him, you won't stop now because he would be prepared and kill you. You plan to make a surprise attack. You see Monster Kid following Chara, they are at the bridge now, you already told for that little dinosaur stay away from Chara. Monster Kid slowly gets close to him.
"Yo...(y/n) told me to stay away from you. She said...you hurt a lot of people."
That silly monster, he will get hurt. You already knew.
"But, yo, that's not true, right!?"
Chara seems to be thinking.
"Yo... Why won't you answer me? A...a...and what's with that weird expression...?"
Chara cames closer to Monster Kid, in a threatening way.
"Oh...oh man..."
Monster Kid turns the opposite of Chara. Then he turns back.
"Yo. Y-you'd b-better st-stop r-right where you are...Cause if you w-wanna hurt anyone else, you're gonna have to get through me, first. A...and...and..."
Chara would hurt him and you had sure about that. Chara raises his hand with the knife, ready for kill Monster Kid, you didn't allow him. You pull Monster Kid behind you and holds Chara's hand.
"What you think you're doing, (y/n)?"
Chara says, with a demonic smile. You answer
"Protecting my friend, demon!"
You push his hand away and quickly pick up your sword. Every attack he did you dodge. You could see him sweating, your attacks were hurting him very well. You felt so strong and powerful, you felt your determination growing, you felt the taste of victory when you saw Chara eating stuff like pie, temmie flakes, crab apple, you knew he was dying. You couldn't help but smile.
Suddenly, you saw Undyne behind him. She would kill him in a surprise attack, but it wouldn't work, because you knew Chara heard her steps and he prepared himself to kill her. When she got closer, Chara would move and kill her, you get in front of Undyne protecting her and taking the damage instead. You wince in pain.
"No!!!!! (Y/N)!!!!!!!! Why have you done that?!?!??!?!" Undyne screams.
Chara gives an evil chuckle, thinking of killing Undyne too, but she quickly makes a spear attack, the spears circulated Chara's soul and killed him in one hit. Monster Kid was so scared and shocked, but he remembed that you saved him, he whimpered
"(y-y/n), p-please, don't...die"
Undyne was crying in worry.
"Y-you won't die, (y/n). I w-won't allow. You have to...stay...with me. Here! I have some bandages in my pocket!"
She begins to put the bandage around the bruise.
"I will take care of you, (y/n). Nobody will hurt you anymore... You will be fine...I swear."
She carries you in a bridal style and takes you to her home. She puts you in her bed and put more bandages to stop the bleeding. She takes her phone and calls Toriel. Toriel arrives and prepares a heal soup for you. Undyne stayed in her kitchen, she was deeply worried about you. After a couple of days, you got better and started living with Undyne, since you lived with Toriel. Then Undyne and you always shared good moments, like fighting togheter, watching anime, protecting the innocents and much more. You are, now, a true hero.
