Both Mega Charizard X and Y are talking, then they spot you and wave you over to them

X: Hey Human! Nice of you to finally walk over here

Y: It’s nice to meet you human! I’m Y and this is my sister X

X: We’re Charizard’s, basically we’re fire dragons! That’s cool right?

Y: We’re also Mega Evolved! Of course I’m the cooler one

X: Nah, I’m the coolest!

Y: Nuh-uh, I’m better

They seem on the verge of a “Nuh-uh and Yeah-huh” Argument
