This is what you came for (RWBY x Undertale Reader)

Error vs Yang

The next morning it was the usual, everyone attended their classes (but with some of (Y/N) kicking butt in sparing matches while the star sanses watched for now) and everybody was at lunch

(Y/N): and that's how I met the star sanses

Blake: that sounds crazy

Ink: but it's all true

Blueberry: especially the part with Lust-

(Y/N): DON'T EVER TALK ABOUT HIM AGAIN!

Gaster: the one thing you fear

at another table Cardin was picking on Velvet

Velvet: Ow stop it!

Cardin: see guys I told you they were real, filthy faunus

then suddenly the air gets a bit cold and (Y/N) teleports by Cardin and grabs his wrist

(Y/N): you might want to let go of her now

Cardin: or what?

Gaster: (Y/N) calm down there is no need to-

Cardin: you going to give me a stupid coat like yours to wear

Gaster: Oh now he's going to get it

(Y/N): ok normally I would do the whole "do you want to have a bad time?" thing but I think i'm just going so skip to the point this time

(Y/N) then knock Cardin across the floor and the rest of his team help him up and they all look angry

Gaster: Wait! *inserts disc into radio* ok now lets do this!

(Y/N) then creates a bunch of bones and puts him and Cardin's team in a cage match in a way then he summons his gaster hands and fires a blast at Cardin who dodges and his other team members try to dog pile (Y/N) but he just teleports out of the way and puts bones were he was and then he finishes Cardin with a blast to the back and then a punch to the gut knocking the wind out of him

(Y/N): *eye glowing* Who else wants to try?!

Cardin's team backs up

(Y/N): thought so

Gaster: *stops music* awww that fight was too short to get into the music

after he gets rid of the bone wall he made then he heads over to the girl who was being picked on

(Y/N): you ok?

Velvet: yes I'm ok now, Thank you

(Y/N): no problem, if he bothers you again just tell me and I'll deal with him

(Y/N) then uses his magic to heal up velvets ear

(Y/N): does that feel better?

Velvet: yes that does feel better Thanks, what's your name?

(Y/N): call me Asterisk, how about yours?

Velvet: My name is Velvet

(Y/N): well nice to meet you Velvet I'll see you around then

after he gets back to his table everybody is looking at him

(Y/N): what?

Yang: that was awesome!

Nora: meh I would have Broken his legs

Weiss: what was that?

(Y/N): I don't like people who pick on people just because they are different, Monster, Human or Faunus it doesn't matter what we are but we all should be treated with respect.
