The Specter Emperor let out a low groan like a dozen trumpets grouped together, and launched a few smaller Specters out from its body, like a cell going through mitosis except it wasn't splitting into two identical cells. Instead, tens of small baby Specters shot out of the Emperor's body like bullets, and flew towards Finn and Iris. Unfortunately for the Emperor, however, Finn and Iris were no easy foes.
Iris smirked and aimed her gun, then unleashed a volley of bullets in rapid succession while flicking her aim from one Specter to another. As she ran out of ammo, she wasted no time trying to reload, and instead called upon her newfound power to send out a barrage of tracking crescent-shaped projectiles towards the Specters. In the matter of a few seconds, the Specters flying towards the two were gone, reduced to atoms, paving a clean way for Finn to gapclose the Emperor.
"Now, Ace!"
"… On it."
