[Mettaton smirks, glancing back at Napstablook with a hairflip to set any actor to shame.]

Are you watching, Blooky? You won't want to miss a second of the show!!

[No seriously. Did this grunt think he was the only theatrical individual on the battle floor? If so, Mettaton's here to prove him wrong via extremely practiced posing. He points to the mess of sludge that passes for a Pokémon and lets out a dramatic groan of disgust, returning his attention to the matter at hand.]

Oh no! How garish!!! Do you really think something as uncouth as your pile of refuse can stand a chance against my beautiful team?! [The arm that was extended in an accusatory point now draws back, tracing down from the crown of Mettaton's head to his chest and settling there; his fingers didn't touch even a centimeter of skin, it's all practiced and flashy.

This was all for show...and then he grins.]

Silky, why don't we show him how a real star battles? Use your Dragon Breath!!

[The Goodra obliges, parting its slimy maw and shooting out a beam of energy towards the Grimer.]
