This is how Thunderwing shows Unicron the Dark Spark goes in Bumblebee's Bot Force.
Ryvine Sparkle: Unbeliveable! Gwen dumped Trent and now Twilight refuse to join you!
Unicron: She's like a hooded female who is named after a bird.
Ryvine Sparkle: You mean Raven. It's no wonder if your most humble servant plays Cross the Street.
Ryvine Sparkle: Hi, buddy. I was thinking that I can send you to somewhere like the Rabbids world to manage your anger. And the Powerpunk Girls are Unicron’s best servants.
Thunderwing: Do you realize that while you have a little chit-chat with Unicron, Ryan is going to use his Matrix of Leadership as a weapon? If he use it, I’ll die.
Ryvine Sparkle: Don’t worry. Maybe there is something I can use.
[He shows Ryvine the Dark Spark]
Ryvine Sparkle: Cool. What does this Dark Spark do?
[Cortex plays an audio clip]
Megatron [voice]: Where the Matrix grants wisdom, the Dark Spark empowers its master to bend the very fabric of the universe and its inhabitants to his will.
Dr. Neo Cortex: So, with this, Ryvine will use it to rival Thunderwing.
Ryvine Sparkle: [grabs the Dark Spark] Cool. Perhaps I can succeed where the late Royal Pain failed and blast Sky High out of the sky. [laughs. To Thunderwing] It's a pun, Thund-wing. That is short for Thunderwing. Not Thunderhead from the Incredibles.
Thunderwing: [chuckles] Do you think you can handle that power?
Ryvine Sparkle: Yes. And alas, I see no profit in having Royal Pain on my side. You can have her. [puts the Dark Spark on his chest]
[Ryvine gets empowered by the Dark Spark]
Ryvine Sparkle: The power! The absolute power!
Unicron: Good. You know what it can do, my student.
Ryvine Sparkle: [talks like himself and Ultron Sigma] Yes, my mentor. The Persona 5 team will know this power. And soon, Morgana shall be my friend once more. With a promise he will make.
[Ryvine thrusts his hand a portal opens up. Ryvine walks towards it, gives a wink to Cortex and goes through it]
Dr. Neo Cortex: I still wonder. Why is Ryvine controlling the Dark Spark but, it's not corrupting him? Do you think it's magic?
Unicron: Not magic, Cortex. But, he is controlling the Dark Spark since my lifeblood flows through him.
Dr. Neo Cortex: You and I know this Dark Energon. Since Megatron got it to Earth, Ryan used his Keyblade to inprison you. So. How did you speak to Ryvine's robo friend now?
