[v.1 Knuckles]

Put up your dukes, I didn't come up for puzzles
I’ll leave your house in flames again, knock, knock, it's Knuckles
Since you have trouble cooking, here's how I’ll manage
Scramble Eggman for my breakfast and for lunch a knuckle sandwich (yeah!)

Your king's child died so he went and increased it sevenfold
Now he's got you getting souls from kids like Chaos Emeralds
Collecting gold, Ebott's hole could fit my treasure trove
Eyes on the prize while you got less perception than a 10 year-old

You lеad Alphys on, I'm the alpha lead with iron fists
You fuck a royal scientist, I royally fuck up sciеntists
Once you've Fallen Down you'll need more than a spear repairing kit
Cause you two match together ‘bout as well as her experiments

Fought Asgore as a kid and all you did was miss him
Flash forward and he bit the dust, now all you do is miss him
I know you like to pour one out since that's what you get saved by
So I’m spilling the tea, a golden flower at your gravesite

[v.2 - Undyne]

Your kind was wiped out by Chaos’ violence, that must be why it's called Angel Island
One’s left and he's too thick-skulled to be a fighter, so for monster kind, I will reap this soul-survivor
Understand, echidna, why I'm fated to win my war?
I'm the only one here with a race left to fight for!
En garde! Battle me and you’re getting bruised
Make your cheeks match your fur like you were left with Rouge
Might get slaughtered by the guard that has the highest honor
With the might of monsters turn Hyper Knuckles to Hypergoner

You don't laugh? Look in the fucking mirror then, Knuckles (why?)
The first thing you did in your first appearance was chuckle
You were feared, you were tough, but now you're reduced to being Sonic's clown
I'm the fish and yet I'd drown, faced with how you're watered down

[v.3 - Knuckles, Undyne]

You talk a big game cause you're suplexing boulders
But you flee from the kid who couldn't hold a controller
When I drop a bar you can't lift, you couldn't bare the hurt
It'll take all monster kind to save her soul after I barrier

At least you'll have done something to demand my respect
Instead of… y'know abandoning the land you protect
If you say you're so determined, why don't you go back and save it?
SEGA made you drop your duties for the green, and you can't escape it!

If your prophecy depicted one to fight for glory
Tell me, how did Monsters Inc. wind up Finding Dory?
I'm giving monster kind hope as they wait to leave
You only know your way around the globe as a racist meme!
I'll knock you out like you just stumbled near the CORE
Calling you Undone when you're a puddle on the floor
I'll take your fighting spirit and spear it ‘fore you can spare it
Strike you down, once more roped in the footsteps of your parents!
