Morphing Horror

Being bathed in flames, the hound writhed momentarily as it crashed through the twisted trees of the constantly-altering realm before the bright inferno was siphoned by an explosive change in mass and shape.

"It's changing forms again!" Kintoki remarked.

"Nothing surprising there–this one is tricky," Sumera noted, adjusting her glasses with a quick breath.

The three combatants stood side-by-side as the Unending Nightmare melded into its new form, compressing the colossal length of its hound form into something vaguely humanoid, clad in a dark-brown exoskeleton.

Antennae sprouted from its head as it took to a bulky, but compressed form, possessing a large stature of a sturdy insect.

"A cockroach," Emilio deduced.

"A wha–?"

Before Kintoki could ask, the nightmare sprung forward with its fresh form, throwing its fist forward straight into the golden-eyed warrior's stomach.

"Pyuh!" Kintoki spit out.
