Miasmic - Doppelganger - The Defector

A fallen creation, reforged in the depths of filth and gloom.
Even among Ionized enemies known for their strange and uncanny qualities, Ionized Doppelgangers stand out as particularly exceptional.
These creatures cloak themselves in a special layer of active Ether ions, allowing them to precisely mimic the appearance of their targets — sometimes so accurately it's nearly impossible to tell the difference. From details to texture, they're masters at blurring the line between real and false.
What makes them even more dangerous is their ability to replicate their targets' powerful combat techniques.
No one knows how they acquire such detailed intel of their targets. Some say they can read minds, pulling the perfect nightmare from their opponent's memory and taking that shape before launching their attack.
"Nonsense! If it could really read my deepest fears, it would turn into a fierce middle-aged woman wielding a clothes hanger! That's right, I'm most afraid of my mom!"

In combat, this enemy uses identical skills to those of their target, launching fierce attacks with blades and guns. After taking a certain amount of DMG, they activates Miasmic Field and unleash powerful, swift piercing attacks.
