They Will Not Believe What I Have Done

And now I'm looking at myself!
Damn it! I look just like them!
I'm here thanks to myself!
Nobody, nobody will observe!

I am the ancient archangel
My name was Adoriel!
Now I'm the angry archdevil
I am Hteththemeth!

I'm burning now from inside
Flames leaving their bodies dried!
They now fear the old words
Destroying all of their worlds!

I am the son of my father
No connection to human kind
On Earth there is no other
To be so good, to be so kind!
Ha ha ha ha ha!

All minions on my side
Let's kill the humans' last ϸride!
Cannot run, die or hide!
Get ready for the Great Ride!

I came into their world!
Yet, I brought my universe also!
The Universe is inside... Me!
