If Karlach had a theme song I think this song would be it...

I believe I've found the perfect fit: "Outsider" by Crypta.

Let me break it down for you. First off, lyrically, this song resonates with Karlach's experiences and emotions, especially considering her tumultuous past in Avernus. The lyrics encapsulate the feelings of being an outsider, which undoubtedly mirrors Karlach's struggles in Avernus.

Furthermore, the title itself, "Outsider," directly aligns with Karlach's background. As a tiefling she's constantly navigating a world where she doesn't quite fit in, and this song captures that sentiment flawlessly.

Now, let's talk about the instrumental aspect. Crypta's intense death metal sound not only complements Karlach's aesthetic as a tiefling that is dressed in black, wielding fire, and unleashing furious rage – but it also amplifies the raw power and energy she exudes in battle. The aggressive yelling in the song mirrors Karlach's ferocity when she enters her raging state.

Overall, "Outsider" by Crypta seems tailor-made to be Karlach's anthem. It encapsulates her journey, her struggles, and her unyielding spirit in a way that few other songs could. Also as Crypta is an all female death metal makes it even more perfect to match karlach.

Here is the lyrics (Hopefully they are correct:

Wandering in a place that doesn't feel like home

Inner disconnection, carving my existence alone

A sickening society where my purpose won't belong

Fabricated ideals, crumbling in a spiral of doom

-

I am the outsider

I am the outsider

Being a bleeding heart in a numb world

Being a bare soul in an invulnerable crowd

Being a blaze in a soil grown cold

I am the outsider

-

Ego feeding from my uncertainties

Telling me tales of unlovability

Sharp sting of rejection cuts through my skin

Solitude hollering - "unworthy, unworthy"

-

I am the outsider

I am the outsider

Like a bloom in a ground made of stone

Like an embrace in a deceitful world

Like deep waters in a shallow pond

I am the outsider

-

I face the demons you tame

I dance in the shadows you fear

I bathe in feelings you disguise

I am the imperfections you hide

-

I am the outsider

I am the outsider

I am the outsider
