JMB as UBOA
TheEternalVanguard as W.D. Gaster

UBOA
Pinching yourself won’t save you this time.
I don’t care if you’re a ripoff, I’m one of a kind.
The lights must be out in your head for you to face me,
Because you’re whiter than the desert to which I will erase thee.
W. D.? He shouldn’t muddle with me.
I play my theme and you’re left in a puddle of pee.
Gaster is a pervert who’s acquainted with crime,
So watch out for the creep in 269.

WD Gaster 
The doctor is here to give you face reconstruction,
Before the darkness leads you into mutated corruption.
I’m otherworlder with the most blasting rhymes ever seen.
You’re gonna get lost like entry number 17.
You’re despicable,whilst I’m invincible,
Just like the CORE, my rhymes are unpredictable.
This monster has the wrong number if he wants to bring hurt.
I’d never let that little head of yours take over my work.

UBOA
In response to that attack, my fun value’s set to 0.
I’m the cut above the rest, actually trying to KILL the hero.
You’re harder to decipher than wing dings,
Your part in this cypher is over with the attacks that I’m bringing.

WD Gaster 
My followers all tell the tale of how i was lead to disaster.
You’re being turned into mundane creepypastas
This man has the upper hand, wouldn’t you agree you two?
Thanks for your feedback! Be seeing you soon!
