The Hero of the Underverse [Male reader x Frisk(s) x Chara(s) x Other(s)]

Waterfall/Undyne

As we were walking into waterfall, I decided to check Frisk's stats.

Frisk ?????

LOVE: 1 Level: 1
At: 5 Df: 72
Hp: 20/20

I was focused on her stats until I heard a voice from above.

???: "Hey!"

Chara: "Crap, it's Undyne."

Y/n: "What is it?"

Undyne: "You are a human. I have to capture you and kill you. Then I will take your Soul to Asgore."

Frisk: "Wait, Undyne, he's our...friend. Please dont-"

Undyne: "I already had to deal with you punk. Asgore didn't say anything about other humans. I will wait at the end of waterfall for you." She said as she pointed at me. I just gave her a cold stare as she left.

Kid: "Yo, Frisk."

Frisk: "Hey Monster kid."

Y/n: "Wait, how strong are you?"

Mk: "I dont really fight yo."

Y/n: "That's fine, it just bugs me that I need literally 2 Exp. points to Level up."

Mk: "So I saw what happened, are you going to fight Undyne?" I smirked.

Y/n: "Yep, you can tag with us if you want to."

Mk: "Okay then." We kept on walking. I did want to wonder something though.

Y/n: "Hey, Frisk, Chara, Why did I become your boyfriend so fast anyways?"

Chara: "I can tell you why."

Frisk: "Wait, Chara noo!" Frisk had a big blush on her face.

Chara: "We experimented on each other a few times, then we started to make us go crazy for more. So now we need a 'stick' in between us." My eyes were widened and I was frozen in shock.I didn't know anything about them doing that stuff. Then some buff seahorse dude came up to us.

Seahorse: "I heard you needed some pleasure girls? Why stick with him when you could go for this." He flexed in front of them.

Both Girls: "No."

Mk: "Get lost, Wierdo."

Seahorse: "Out of the way, pipsqeak." He pushed monster kid as he kept flirting with the girls.

Y/n: "Yep, you will do just fine." Then I grabbed him and threw him back. "Whats your name, asshole?"

Seahorse: "Aaron, and you wanna go?" I took my shirt off.

Y/n: "More than you know." I charged at him with a punch.

MISS

Aaron: "That all you got?" He threw a flex punch at me.
