This is how Hawk Moth influences Budgie in The Rise of Ladybug.
[The akuma lands on Budgie's tuft of hair. A butterfly shape forms around his eyes]
Hawk Moth: Hawk Moth is my name. Rotor is now yours.
Budgie the Little Helicopter: Really? What are my powers?
Hawk Moth: I hereby grant you the ability to create huge winds, wirlwinds and twisters. And I need to do a task for me when the time is right, if it's ok with you.
Budgie the Little Helicopter: You got it, Hawk Moth. Rotor is on the job.
[Budgie lets the akuma cossume him]
Budgie the Little Helicopter: No more mr. nice copter.
[Budgie turns into Rotor]
Rotor: Time to bring on the wind.
[Rotor flies off]
Thomas: Hi, Twilight.
Twilight Sparkle: Hey, Thomas.
[A strong wind begins blowing. Thomas and Twilight look up]
Twilight Sparkle: What's happening?
Thomas: Budgie? What are you doing here? And why are you like that?
Ryan F-Freeman: Please don't tell me the Dazzlings got you under their spell.
Rotor: Oh. I'm not Budgie the Little Helicopter anymore. I'm Rotor.
[Rotor blows a strong wind]
Sci-Ryan: If you would use Twilight's amulet on me, am I transform into a Midnight Sparkle version of myself, Ryan?
[A fierce wind blows]
Ryan F-Freeman: What is that?!
Rotor: [evil laugh]
Ryan F-Freeman: The Dazzlings! I knew it. They're controlling you, Budgie!!!!
Rotor: Oh, Ryan. I'm not controlled by the Dazzlings. I'm not Budgie either.
Ryan F-Freeman: I'll remove you!![uses his magic to remove Hawk Moth off of Budgie]
Rotor: HA! If I can posses Budgie. Maybe I can possess you!!!
[Midnight Sparkle used her magic to separate Dark Ryan from Ryan and the akuma strengthens]
Ryan F-Freeman: Uh oh.
Rotor: Oh, Ryan. With your body my power will be increased and will continue to grow until Hawk Moth will have power to defeat Ladybug and Cat Noir!
Dark Ryan F-Freeman: Oh you're wrong. Unlike you, I CAN have everything I want!
Ryan F-Freeman: Uh, Dark Ryan?
Dark Ryan F-Freeman: What did I say, Ryan?
Ryan F-Freeman: You meant to say what Sunset said to Midnight.
Dark Ryan F-Freeman: I said what Midnight Sparkle said. Sorry. [clears throat] Budgie! You can't do this!
Rotor: Why not? This is Ryan over there and he's just filled with magic!
Dark Ryan F-Freeman: But, you're destroying him to get it!
Ryan F-Freeman: I want to understand magic but I'm too young to be exterminated!
[Dark Ryan saves Ryan and he gets in Dark Ryan's body]
Rotor: So what? There's more magic
