This is how the birth of Terror-Blaze goes in Horrificator (CTaRAoMToLaCN).

[Ryan finds Aria alone]

Ryan F-Freeman: Hey, Aria. What is the matter?

Aria Blaze: Mylène's been akumatized and she's taken my sisters!

Ryan F-Freeman: I know. We'll get them back, I promise.

Aria Blaze: [growls clenching her fists] If I could only teach Horrificator the true meaning of fear, then she would be sorry she ever held my sisters captive! [runs off]

Ryan F-Freeman: Aria! Wait!

[But, she's gone. Rikki pops up]

Rikki: Was it something you said?

Ryan F-Freeman: I'm not sure. I'm sure she'll get over it sooner or later.

[At Hawk Moth's lair]

Ryan Repulsa: Oh, partner. I sense a Dazzling bandmate. [in sing song] And she's got anger issues.

Hawk Moth: I do like the smell of anger in the morning. It is the very thing that fuels the Akuma you send.

[Ryan Repulsa fills an Akuma with dark energy]

Ryan Repulsa: Fly now, my brave Akuma. And evilize the... Purple haired... Siren? Whatever. Just go.

[The Akuma flies out of the window. Aria stands in the school toilets staring into a mirror]

Aria Blaze: Horrificator should be ashamed for what she's done.

[Sorina peeks to see an Akuma fly in through the window]

Sorina: A butterfly in here? Aria! Watch out!

[She tries to hit it but gets knocked out on the floor. The Akuma lands on Aria's gem and a butterfly frame forms around her eyes]

Ryan Repulsa: Terror-Blaze. I am Ryan Repulsa, partner of Hawk Moth. I know you felt fear like the NEXO Knights before you. I can help you turn the tables by giving you the powers of Horrificator. But, in return, you need to bring me and Hawk Moth the Miraculous and a relic of the Primes called "The Matrix of Leadership". So. You know what a girl named Gloriosa said?

Aria Blaze: Yes, Ryan Repulsa.

[Aria lets the Akuma consume her and she becomes Terror-Blaze]

Terror-Blaze: I got this.

Sorina: Aria? You ok? I am so sorry.

Terror-Blaze: I am Terror-Blaze. The inflictor of fear.

[Sorina laughs because what Terror-Blaze said]

Sorina: [stops laughing] Oh. Sorry. I think Crash would be afraid.

Terror-Blaze: Oh, I'm not afraid. But you soon will be!

[Sorina screams as Terror-Blaze grabs her and teleports away. Evil Anna hears]

Evil Anna: Oh no. Aria! I got to tell Galvatron!

[She runs and finds him with the others]

Evil Anna: Galvatron! Aria's now Terror-Blaze!

Megatron: Really? Show me.

[She shows a photo of Terror-Blaze to her friends]

Ranyx: Aria? She is more scary then Starlight.

Bertram T. Monkey: Ryan. Find Marrinette and transform. I'll protect Sunset.

[Ryan nods and goes to see Marrinette]

Ryan F-Freeman: Marrinette. I think Aria is now Terror-Blaze.

Rikki: And he needs your help to stop her.

Marinette: Okay. Tikki, time to do your thing.

Tikki: Okay.

Ryan F-Freeman: Time to do like we Practiced. You go first.

Marinette: Tikki, Spots on!

[Marinette becomes Ladybug]

Ryan F-Freeman: Here we go. Rikki, spots on! Ha!

[Rikki flys into Ryan's bracelet and Ryan transforms to Ladyan]

[Terror-Blaze appears beside Horrificator]

Sorina: Let me go! You don't know who you are messing with! 

Terror-Blaze: Horrificator, I have your next victim.

[Iago spots Sorina and flys in to save her]

Iago: Go Sorina! Run!

[Sorina runs away]

Terror-Blaze: [growls] Pesky bird! You'll pay for that!

Iago: I got to go. [flies off panicking]

[Ranyx appears]

Ranyx: Stop this at once, Aria!

Terror-Blaze: I am not the Aria Blaze you know anymore. Now, I am the inflictor of fear, Terror-Blaze.

Raynx: Wait a sec. [goes to Ryan and the others]

[At Hawk Moth's lair]

Ryan Repulsa: Sorina got scared. It will not be long before Ladyan and Kitty Noir show up to meet their fears and then their doom. [laughs like Midnight Sparkle]

[Back at the school]

Ladyan: Ranyx? Sorina? Iago? What's wrong?

Sorina: Horrificator and Terror-Blaze are trying to absorb our fear.

Iago: We need to be protected from them! Where is Meg and Adrian?

Ladybug: You mean Cat Noir and Kitty Noir?

Flitter: Ranyx, you need to be brave and transform. You know why your name was Ryan?

Ranyx: Yes, now come on.

[Flitter nods]

Ranyx: Flitter, wings open!

[He becomes Flutterwing]

Crash Bandicoot: Ok, we need to split into groups of five so the 2 villains won't get us. Me and Thomas will lead Iago, Blades, Knock Out, Breakdown, Grimlock and Drift.

Bertram T. Monkey: I'll protect Sunset and Blythe.

Megatron: I'll protect Starlight and Emmet.

[Emmet spots a yellow light]

Emmet: Oh no! It's the Ghostlight! Get back, you! Return from where you came!

[But, it turns out to be Ryinker Bell]

Evil Ryan: Oh. It's just Ryinker Bell. The Ghostlight is not yellow anyhow. Mater said the Ghostlight is blue.

Roxanne (Rianna's Nobody): I can help as well. Silvia, sing out!

[Rianna transforms into SwanSong]

Blades (Rescue Bots): SwanSong? Do you think the Ghostlight is real like you?
