Full title: We Are Number One but it's Sung by Ken and for some reason Fates! Anthony has a Trombone while Reinhardt and Berkut just stand there confused

Ken: Are you, uh, a real villain?
Anthony: Well, uh, technically... nah.
Ken: Have you ever threatened someone's life?
Reinhardt: Nah.
Ken: Have you ever tried a disguise?
Berkut: Why would I try that peasant?
Ken: Alright! I can see that I will have to teach you how to be villains!

Anthony pulls out a trombone and plays that famous opening bit

All
Hey!
We are Number One
Hey!
We are Number One

Ken:
Now listen closely
Here's a little lesson in trickery
This is going down in history
If you wanna be a Villain Number One
You have to chase a hero on the run
Just follow my moves, and sneak around
Be careful not to make a sound
Reinhardt: Shh
Ken: No, don't touch that!

All:
We are Number One
Hey!
We are Number One
We are Number One

Ken:
Ha ha ha
Now look at this net, that I just found
When I say go, be ready to throw
Go!
Throw it on him, not me!
Ugh, let's try something else
Now watch and learn, here's the deal
He'll slip and slide on this banana peel!
Ha ha ha, gasp! what are you doing!?

All:
Ba-ba-biddly-ba-ba-ba-ba, ba-ba-ba-ba-ba-ba-ba
We are Number One
Hey!
Ba-ba-biddly-ba-ba-ba-ba, ba-ba-ba-ba-ba-ba-ba
We are Number One
Ba-ba-biddly-ba-ba-ba-ba, ba-ba-ba-ba-ba-ba-ba
We are Number One
Hey!
Ba-ba-biddly-ba-ba-ba-ba, ba-ba-ba-ba-ba-ba-ba
We are Number One
Hey!
