Croa

Croa commands the deadly element of chlorine, capable of creating lethal chlorine gas at will.

He exhibits an almost inhuman facial structure and is famously nicknamed "Gas Chamber" and "The Purifier Croa."

Despite using polite language, Croa’s demeanor is pure cruelty, delighting in the agony of others.

He is a tall man, always seen in a long-sleeved white coat, with a constant aura of chlorine vapor around him.

People around Croa often notice a pervasive "pool-like" smell due to the ever-present chlorine.

Croa is a sadistic murderer who finds pleasure in slaughtering innocents.

He embodies brutality, going far beyond what his monstrous appearance suggests.

His speech remains courteous even as he subjects his victims to extreme suffering.

Croa kills not out of necessity, but for his own twisted enjoyment.

During the Croatian conflict, Croa incited Croatian soldiers to attack a Serbian church where Teresa Beria lived.

He used chlorine gas to murder the church's mother superior, killing indiscriminately under the guise of "ethnic cleansing."

Croa orchestrated the mass rape of the church’s nuns by the soldiers, and once they were physically and mentally devastated, he executed them with chlorine gas.

These atrocities left Teresa Beria with permanent, severe trauma.

Later, Croa attacked in an attempt to capture Tomo Yamanobe, coming face-to-face with Sasha (Alexander Nikolaevich Hell).

He fought savagely, transforming a pond into concentrated hydrochloric acid to gain the upper hand, putting Sasha at a disadvantage for a while.

With support from Ekaterina Kurae, Sasha eventually managed to defeat Croa, slicing him down and giving him the gruesome end he deserved.

Croa is the Chlorine Qwaser, manipulating chlorine to form deadly gases and chemical weapons.

He can alter nearby bodies of water into hydrochloric acid, turning the environment itself into a lethal trap.

His control over gas makes him especially dangerous in close quarters or crowded areas.

A large and imposing figure, Croa stands out in a pristine, long, white coat with overlong sleeves.

His face is distinctly inhuman—unnerving to behold, matching the monstrosity of his actions.

Wherever he goes, a strong smell of chlorine lingers, making even passersby uneasy.

Croa’s acts during the Croatian conflict are remembered for their cruelty and horror.

He left deep scars on his victims, most notably Teresa Beria, shaping her future and trauma.

Though ultimately slain, Croa's reign of terror stands as one of the darkest chapters associated with the Adept.
