Devack quotes from Yu-Gi-Oh! 5D's

Devack

I now activate Magician Ape's special ability. Which means that once a turn, if I take one card from my hand and send it to my graveyard, Magician Ape is able to take control of one of your monsters. And with that out of the way, Magician Ape attacks you directly!

Devack

All you've done is prolong your misery, boy. You don't think you'll really win, do you? You can't defeat me. And then when I'm through with you, I'm coming after your sister next!

Devack

I'm glad you finally joined us, Luna. My earthbound immortal has been waiting patiently. Let's duel, signer!

Yusei

All right, Dark Signers, this is it. It's time to pay for what you've done!

Devack

Well, before you try and cash out, I have something the little girl might be looking for. [holds out the Ancient Fairy Dragon synchro monster card]

Luna

That's Ancient Fairy Dragon!

Devack

I believe this card should be in your deck. Now, if you want to get this card back, you'll have to come battle me, and in case you're wondering who I am, my name is Devack. And I bear the mark of the monkey.

Leo

So if I'm in the middle of this monkey barrier, that means…

Devack

[appearing] Who are you? What's going on? You're not a Signer. What are you doing here?

Leo

[fiercely] I'm here to duel you! That is if you think you're strong enough to take me on!

Trudge

Leo!

Devack

Is this some kind of joke? Where's the little girl? Why isn't she here? I told her to come.

Leo

Yeah, well, she's busy. You're gonna have to duel me instead, mister! I may not be a Signer, but that doesn't mean that I can't rock a deck! Now come on! Let's see what you're made of!

Devack

I applaud your enthusiasm. I really do. But I'm afraid that you simply do not have the power to match me, boy.

Leo

You don't know that!

Devack

If you insist on being destroyed, so be it.

Let's duel!

Devack

I sense good things. [laughs sinisterly]

Leo

What are you talking about?!

Devack

You human beings, so narrow minded. You have no idea that this battle is being waged in the Spirit World as well. I assume that's where your poor sister is right now, isn't she?

Leo

Leave Luna out of this! You're dueling me! Now draw your card and go!

Devack

My pleasure. Though once you see what I have in mind, you'll wish I waited! Now, meet your doom in the guise of my dark tuner monster, Dark Ape!

Leo

Wha…?

But it's powerless!

Yusei

Not for long. Just watch.

Devack

Your friend Yusei knows what he's talking about. Behold! By using my Dark Wave spell, I can convert a monster's level into negative energy. Now you can witness the real purpose of my Dark Ape, as I use him to combine forces with Fighter Ape! [chanting] When the shadows are devoured by even darker shadows, the curtain pulls back and reveals… a world without light! Come forth, Zeman the Ape King!

Leo

Oh, no! It's gonna take me and my friends away!

Devack

You don't have to worry about that. This immortal requires a different kind of power source… one that exists in the spirit world. By the power of the Dark Signers, I summon Earthbound Immortal Cusillu!

Devack

[advancing towards Luna and Leo after they've defeated him; trembling and crumbling] You think you've won? This isn't over! I won't fall alone! You're coming with me!

Yusei

We gotta get down there, now!

Devack

You will not stop the shadows from devouring this world, for I will destroy you! I will drag you down into the Netherworld! [vanishes]
