He's so focused on their fight that at first, he doesn't recognize that the words from Scaramouche aren't coming from his mouth, but rather directly to his mind. His eyes widen with delight, the smile on his face wider and more unhinged. He's asking for him to really, truly go all out- and there's nothing he'd like to do more than to grant this wish for his companion.

"So you're ready to be defeated so soon? Alright. I won't keep you waiting."

Skidding to a stop as he puts some distance between himself and Scaramouche, Childe begins his transformation without hesitation. Electricity and water spike outwards and splash around him, the power from beyond the stars swirling around him as it shakes the very foundation of the ground beneath their feet.

The dark armor, the Demon King's Armament begins to clasp itself to his arms and legs, changing his body to something a little less human, power surging outwards that threatens to knock over lesser beings. As it completes, a surge of dark energy radiates out from his core, bearing the weapon that showcases the very stars that circle Teyvat- and he stands up to his full height, staring down at his opponent.
