When Sonic and the others heard those voices, they were curious about who are they. When the two mysterious characters appeared, Catboy was the first one in getting shocked.

???: Well Pj Masks, like I said, I will come back

Catboy: Romeo?!

Sonic: What? Do you know him?!

Owlette: Yes, he's our worst enemy

An-Yu: And it looks like he's not alone!

Romeo: That's right dragon girl, your friend is with me too

Nazo: Yes I am!

Vampirina: It's Nazo!!

Silver: Wait, is he an enemy too?

Bridget: Yes, he attacked Owlette with his ray

Shadow: If you are an enemy of the Pj Masks, you must be from the city!

Romeo: Yes I am, black rat!

Shadow: What?!

Marshall: Hey! We are in your side too Pj Masks!

Nazo: What are those? Your pets?!

Ryder: They are MY pets and MY team!

Chase: Yeah, that's right! And we are on their side too!

Sonic: Nazo! Romeo! Whatever you are going to do, it won't work

Romeo: Shut up, you blue pest!

Catboy: Hey! Don't call Sonic like that!

Romeo: Why, is your friend?

Nazo: They are, he protect him when I was attacking

Gecko: Well, YOU started by attacking An-Yu!

Tails: And you wanted Catboy's powers!

Ryder: If you wanna destroy this island, you first need to mess with the Paw Patrol

Sticks: Paw Patrol?

Rouge: Is that the name of the team?

Zuma: Yes it is

Nazo: Well then, if that it...

Nazo teleported near to Ryder and he shot his ray at him

Ryder: AHHH!!!

Skye: RYDER!!

Sonic: No!!! Stop that!!

Romeo: Too late!

Chase: You cowards!!

Sonic: Ugh!! I... get... enough... of you!

Shadow: Sonic, are you alright?!

Sonic: Argh!!!

Skye: What's happening to Sonic?!

Catboy: I don't know, but someone has to heal Ryder

Manic: Knuckles! Can you help him?

Knuckles: Sure, but I need some rings

Everest: I can help you!

Rocky: Me too!

Rubble: Count me in!

Knuckles: Okay, I'll be waiting for you

Sonia: Okay brother, now everything is al--

Catboy: SONIC!

Shadow: No Sonic, don't let you anger get to you!!

Sonic: ARGH!

And then Sonic was transformed into... Dark Sonic!!!

Skye: What the...?!

Chase: Sonic?!

Nazo: Ugh, not this form again!

Romeo: Don't just sit there Nazo, get them!

Dark Sonic: Don't ever try to get me, cowards!

Nazo: You!!!

Vampirina: What's gotten into Sonic?

Shadow: Is his negative energy and his anger, it turn him into his Dark form

Catboy: He may be angry of what they did to Ryder

Skye: But... who's going to stop them?

Amy: Yeah, he has Chase's emerald, and he must be much stonger now

Shadow: Skye! You better stop them!

Marshall: What? Skye is going to stop them?!

Chase: Why Shadow?

Shadow: Nazo can only be defeated by someone with enough positive energy

Catboy: And Skye was always positive in our way here, that's more than enough positive energy

Owlette: Like you Catboy, you were positive when you attacked Nazo and saved Sonic

Skye: Okay! I will try!

And Skye flew to Nazo and Dark Sonic's fight

Dark Sonic: Now is your end!

Nazo: I don't think so!

Skye: Stop this fight you two! Chaos Control!

Rouge: Wow! How did she did that?!

Shadow: She is using her Chaos Emerald!

Catboy: So that means we all can do it?

Shadow: Yes you can, cause you even have a emerald

Catboy: Cool!!

Nazo: How did you do that?!

Skye: I have a Chaos Emerald, so I can do that. Try to catch me!

Nazo: I will catch you, little dog!

Dark Sonic: Skye? No... I can't... let my anger control me! I will hurt her and the others!

Skye: Now I got you Nazo!

Dark Sonic: (falling) SKYE!!

Skye: Huh... Sonic?!

Romeo: Hah! Now you have to save your friend!

Skye: Sonic!!!

And then...

Owlette: I got him!

Sonic: Phew, thanks Owlette!

Owlette: No problem! Now Skye, get him once and for all!!

Romeo: Hey! How did you... I will get that dog!

Catboy: No you won't!

And Catboy used his stripes to tie Romeo

Romeo: Ugh! You kitty!

Catboy: I'm not a kitty anymore Romeo

Skye: Okay, let's finish this!!

Nazo: As you wish!!

Skye and Nazo get rays to each other. At first Nazo was stronger than Skye, but Skye got a lot of positive that she make a big ray that shot Nazo

Nazo: ARGH!!!

Sonic: She... she did it!!

Catboy: Skye, you did it!!!

Chase: Yeah! You did it!!

Blaze: Your positive energy won against the negative energy that Nazo had

Vampirina: Speaking about him, where he is?

Silver: Do you think he vanished?

Shadow: No! He there!

Romeo: Hah! You guys don't have much power as I thought

Chase: Wait... he looks... different

Skye: Nazo? Are you okay?

And when she looked at him, he saw that he was transformed into a dog

Nazo: Ugh... what happened?

Rocky: Hey! What happened here?

Sonic: Nazo? You're...

Nazo: What? I'm... a dog

Romeo: Nazo! Why are you standing there, attack them!!

Skye: Shut up Romeo!

Nazo: Skye! I'm... sorry about hurting your friend Ryder

Skye: What? You're... sorry?!

Shadow: Why?

Chase: Maybe her positive energy changed Nazo into a dog and removed his negative energy

Catboy: So Nazo... you don't wanna hurt us?

Nazo: N-no, I won't hurt you!

Sonic: Well... I'm sorry if I get too angry with you and Romeo, for me was not good what you did to Owlette and Ryder

Nazo: So... you'll forgive me?

Skye: Sure Nazo, everyone needs a second chance

And Skye give her paw to Nazo as an accept of his forgiveness

Nazo: (blushing) T-thanks Skye, but I don't know if I can do something to get Ryder back to you

Rubble: You don't, but we do!

Chase: Guys! Knuckles!

Gecko: They must be helping healing Ryder

Knuckles: Yes we do! And we are ready!

Knuckles used the power of the Master Emerald to heal Ryder and it worked. Ryder opened his eyes and he was surprised when he saw everyone

Ryder: G-guys... where am I?

All Paw Patrol: Ryder!!!

Sonic: You are alive!!

Owlette: Good job again Knuckles!

Knuckles: (blushing) Uh... thanks Owlette

Nazo: Ryder... I'm sorry if I hurt you with my ray; I may have wanted to, but that was because of my negative energy

Ryder: It's okay Nazo, I forgive you

Silver: Hey! Where is Romeo?

Zuma: Yeah, he was here just a moment ago!

Marshall: Did he escaped?!

Catboy: It can't be possible, my stripes are very strong!

Vampirina: Wait, there something on the ground!

Shadow: That's... the doctor's sign!!

Tails: So Eggman was the one who let Romeo free?

Amy: Or maybe...

Sonic: Romeo must be one of Eggman's allies! That sign only can come from a person!

Catboy: So that means... he is working with your enemy?!

Shadow: That stupid doctor!

Silver: Yeah, he is allies with one of our new friends!

Skye: Hey Nazo! Do you know if that is true?

Nazo: Yes, Romeo is an ally of the doctor

Gecko: No way!!!

Chase: Don't worry, I will track Romeo down, look!

Sonia: The sign is... a radar!!

Poppy: So that's how he track us!

An-Yu: Maybe it can even track Romeo down

Sonic: Alright, let's track that scientist down!

Nazo: Can I help as well?

Catboy: Sure Nazo, follow us!

Nazo: Good

And they were off to get Romeo. The Pj Masks were shocked that Romeo was working with Sonic's enemy all along, but they needed to get him cause he still had Chase's emerald, so they were REALLY decided to go and stop him
