Hoopa: "Hey, Eternatus!"
Eternatus: "w-what is it?"
Hoopa: "this!"
*In a little sequence of flashing lights, Hoopa formed into his true form. Wow, he's a lot more bigger now*
Eternatus: "Woah! You-ur Dynamax form looks aw-wesome! (I didn't even know-w you-u could Dynamax)"
Hoopa: "Dina... Max? What is that? This my true form. I just prefer my small form more. Was is a Dynamax anyways?"
Eternatus: "Dynamaxing i-is w-when a Pokémon-n grows bi-igger due to a surge o-of pow-er. S-sometimes, even-n changing thei-ir appear-rence."
Hoopa: "oh cool! Say, I've heard you Dynamaxed before. Can you show me?"
Eternatus: "I-i rather-r not..."
Hoopa: "Why not? It'll be awesome!"
Eternatus: "C-can I-i j-just Gynamax y-you i-instead?..."
Hoopa: "I like your offer..."
Eternatus: :3
Hoopa: "But, you're dodging the question."
Eternatus: :(
Hoopa: "I showed you my true form, show me your Dynamax form! Please? I promise to not tell Zacian and Zamatana!"
Eternatus: "y-you p-promise?..."
Hoopa: "Yep! I promise to the ends of my rings!"
Eternatus: "O-okay..."
*Eternatus thought long and hard. And in mere seconds Pink-ish light was surrounding him. The dragon then flew up up high in the air, feeling large amounts of pain with him. And in a pink flash, Erternamax appeared. Hoopa, frightened by Eternamax's appearance. Hoopa poofed into his small form*
Hoopa: "WHAT THE FUCK!?!?"
Eternamax: "I-i'm 100 meters long in this form. A-and t-that's how l-long I-i am curled u-up."
Hoopa: "MOTHER OF ARCEUS!!! CURLED UP!?!?"
Eternamax: "yeah... C-can I-i t-turn back into my n-normal-l f-form now-w? I-it reall-ly hurts-s to stay-y l-like this..."
Hoopa: "YEAH, YEAH. GO DO THAT!"
