Undertale Harem x Male Rainbow Reader:

In this story you fell into the Underground with Frisk and you have a soul with every traiti.

However, this creates some problems.

Thanks to you possessing so many different traits it essentially gave you split personalities.

Your Determination is your main one and each personality has access to different weapons they can summon and different triggers to activate them.

I still haven't figured out too many details like how each will be triggered or how they act fully but I'm working on it.

Red:
Your Determination and main self.

You're essentially like a Shonen Protagonist here, selfless, enthusiastic and reckless.

You'll risk your life for those close to you and won't stop once you've set your mind to something.

Item:
Red Dagger

Cyan:
This side of you is extremely cautious and shy, you like to assess the situation and not jump to conclusions, almost the exact opposite of yourself normally.

Item:
Cyan Knife

Orange:
This is your main self turned up to an eleven.

You'll keep going no matter what and try to muscle through every situation.

Any challenge in your way you'll facedown and step up to.

Item:
Orange Gauntlet

Green:
Like this you are very kind and understanding.

You can't bring yourself to stay mad at anyone and you'll forgive them no matter what.

You like to see the good in everyone and will help no matter what.

Item:
Green Shield

Blue:
You are uptight and smug like this.

You're more of a douche like this, but not a bad person as you'll still help others, you'll just be a little more entitled.

Item:
Blue Shoes

Purple:
Like this, you are the most stubborn person on the planet.

Similar to your orange self, you'll keep moving forward without hesitation.

Unlike your orange self though, you'll also go out of your way to motivate others.

Item:
Purple Pen

Yellow:
You're like an old school superhero.

Think like All Might in his muscular form.

Proud, upstanding and a true hero through and through.

Item:
Yellow Gun

Black:
Cruel, merciless and heartless.

This is you at your most dangerous, a vile beast who only gains pleasure from the suffering of others.

When you're like this, the Mercy option is completely removed until a battle ends.

Item:
Black Scythe

Harem:

Frisk and Chara:

Sans and Papyrus:

Toriel:

Napstablook:

Mettaton:

Undyne:

Alphys:

Muffet:

Nicecream Gal and Burgerpants:

Asriel/Flowey:

Asgore:
