NOTE: I do not own the song "I'm the Bad Guy" from Wander Over Yonder. That belongs to Disney, mind you.
"So..." Baron Penfold, with his polka-dotted Nero on his shoulders kept his eyes locked on Danger Mouse from where he's sitting. "You must be the good guy from the other universe if those idiot friends of yours sent you here by accident instead of Sinister Mouse."
"You knew Sinister Mouse?" Danger Mouse had the nerve to ask the evil hamster that question. "Is he like... your assistant or something."
The evil hamster and his polka-dotted Nero both laughed hysterically at Danger Mouse. Seeing Baron Penfold laughing hysterically like an evil villain made Danger Mouse's heart stop every 5 seconds from that. He had never seen anything like that before in his entire life. Fighting for his life against dangerous villains that want to murder him? Piece of cake.
This scene?
He might have troubles looking at his Penfold the same way again if he manages to get back to his own universe.
After a minute of laughing hysterically, Baron Penfold and his polka-dotted Nero have calmed down, but not before the hamster stares at Danger Mouse with an evil glare, not to mention a sinister grin.
"Since you're new here," Baron Penfold spoke to Danger Mouse. "Allow me to explain in a way I think a smart fellow like you are capable of understanding, unlike the other two idiots I've just met before you."
Oh, I hope it's not one of those blasted villain musical numbers you hear in animated flms!
"Through song!"
Dang it! I hate cheesy musical numbers! So the villain song starts to begin and Baron Penfold is... dancing?! Oh no! He's not actually doing a musical number in this chapter in front of Danger Mouse, is he? Hang on! Is that that one song from that blasted Disney cartoon "Wander Over Yonder"?
No! No, no no! He's not... he's not!
Someone stop this madness! This is torture! TORTURE!
Baron Penfold: I'm not the hamster-in-distress
The evil hamster gets himself off from the metallic chair and approaches Danger Mouse up close.
Baron Penfold: I'm not your sidekick or the faithful assistant
I'm not a little bird who needs your help to fly
Nope
Dark shadows covered up the entire area, leaving Danger Mouse completely in the dark, unable to see Baron Penfold sneaking up behind him.
Baron Penfold: I'm the bad guy
The area lights up to allow Danger Mouse to see several prison cells full of some of the universe's most evil and dangerous villains, including Baron Greenback and Stiletto who are locked up in one of the cells.
Baron Penfold: All these former villains that you see
Each of them, with shaking knees, has knelt before me
So I'm not your teammate or your partner-in-crime
What am I, boys?
"He's the bad guy." The imprisoned villains cried in unison.
"And a terrible one, too! Release me from this vile prison, you foolish hamster!" Baron Greenback shouted angrily before being knocked unconscious by Baron Penfold's cane.
"Shut your mouth, toad!" Baron Penfold barked at the unconscious toad before resuming singing.
Baron Penfold: Oh, it's magic to watch a country
Shrivel up and die

Meanwhile, a not-very-important country that is located somewhere in... Europe of the Twistyverse, gets blown up into tiny bits by a huge laser ray from one of Baron Penfold's satellites, thus removing the not-very-important country from the world map, and claiming millions of innocent lives.

Danger Mouse swore he could've heard the screams of terror and agony from outside whatever the place he's in right now before Baron Penfold grabbed one of his hands and pulls him towards him, forcing him to waltz with the evil hamster who resumes singing.
Baron Penfold: Oh, it's thrilling to be a villain
The hamster leans closer to our confused hero...
Baron Penfold: I destroy their homes and then I watch them cry!
... and proceeds to drop him onto the ground, who just lie there in pure shock.
"Cuz I'm the bad guy!"

Meanwhile, in our real universe, Penfold and Danger Toad managed to subdue and restrain Sinister Mouse before he can do any harm in our world again as they try to find the correct alternative universe to go into to find Danger Mouse before Baron Greenback tries to do any harm on him since the both of them (and Stiletto and Nero) are stuck in the same universe.
They've went through multiple universes to find the right one. There's Chalk Universe, Disney Universe, Looney Tunes Universe, Hanna Barbara Universe, Simpsons Universe, Family Guy Universe, South Park Universe, Crayon Universe, Adventure Time Universe, Steven Universe...
"Um, Steven Universe is a fictional character, not an actual universe." Penfold corrects the narrator. "Might want to give the show a try."
... a universe where strange beings with two arms and two legs with bare skin are the dominant species, a universe where candy and sweets are sentient beings, a universe made entirely out of Lego pieces, the list goes on!
"I like the Gravity Falls universe." Danger Moth said as she appears out of nowhere.
Danger Moth?! What's next? Colonel K's hologram making an appearance?
"I really like the Mustache universe, Pinfold." Colonel K's hologram said as he appears... also out of nowhere before turning to his right to see a subdued Sinister Mouse tied up to one of the wooden piers, his left to see Danger Toad waving hello to the hologram and then giving Penfold a firm look.
"Someone explain to me why Baron Greenback is all of a sudden the good guy, why Danger Moth is here where she should be back in HQ controlling her natural instincts and when in the Queen's name did Danger Mouse start wearing red?"
Penfold and Danger Toad exchanged nervous glances to each other.

Back in the Twistyverse, Baron Penfold's musical number is still playing. Somebody end it already!
Baron Penfold: Oh, ain't it fantastic?
The evil hamster spots Quark trying to make his escape.
Baron Penfold: I see something, I blast it!
He pulls out a ray gun from behind and shoots Quark right back into his cell, with Danger Mouse having to witness that. And then he blasted the narrator multiple times before the narrator could say something.
Baron Penfold: And let me tell you why
He presses a random button from his console. One of the tiles from the floor, the one tile where Danger Mouse is standing on, lights up and, before the one-eyed secret agent could react, a spherical force field entraps him inside. Baron Penfold just stood there, watching Danger Mouse trying all he can to get himself out of his spherical prison.
Baron Penfold: I've always had a weakness for barrenness and bleakness
I crush all your hopes and then I watch you cry!
"You fiend!" Danger Mouse felt that he had no choice but to express his anger at Baron Penfold. Forget the fact that he looks exactly like his Penfold.
Baron Penfold: See, I find this business rather fun
I don't want your friendship or your adulation
I'll vaporize your universe and bid it bye-bye
Why?
Danger Mouse glared at Baron Penfold. "Because you're the bad guy."
"Precisely." Baron Penfold replied before letting out a maniacal laughter that sends shivers down to Danger Mouse's spines.
