—Corroder killing Dorothy and Albert with sulfuric acid

Corroder (硫酸男 Ryūsan-otoko), real name John Haigh (ジョン・ヘイグ Jon Haigu), is the second boss encountered in Clock Tower 3. Possessed by an Entity, he is a serial killer who uses concentrated sulfuric acid to scald and burn his victims to death, and then dumps their corpses in containers to dispose of the evidence. He wears a gas mask and a suit to protect him from the acid. He wears his acid like a backpack and uses a hose with a nozzle to spray his acid.

Clock Tower 3[]



Corroder murders Dorothy and Albert Rand.

He is first seen blinding an elderly woman, Dorothy Rand, and her adult son, Albert Rand, before throwing them both alive in a drum of sulfuric acid in November 1963. After murdering them, he robbed them of their cash and fled the crime scene.

He claimed to be a distant relative of the Rands - it is unknown if this is true. He had 31 victims and was sentenced to 605 years.

During the game, he pursues Alyssa Hamilton, attempting to murder her. He is eventually defeated.

Near the end of the game, his deceased "spirit" is seen at the Ritual of Engagement with the rest of Dick Hamilton's Subordinates. All of them disappear when Alyssa uses the power of her Clover Necklace.



Corroder's murders in a newspaper.

23 November 1963. Crawley, West Sussex -- Two decomposed corpses were found in a house in Russell Street on Tuesday. The victims were Dorothy Rand, 65, and her toy-maker son, Albert Rand, 34. They were found in a drum filled with acid in the garage adjoining their house.

The suspect is believed to have escaped with a sum of money after the grisly crime. Albert Rand lived together who his mother, a widow, who was certified blind and required assistance in everyday tasks. Mr. Rand's eyes had been gouged out prior to his murder, and police profilers are on the trail of the man who committed such a monstrous crime.

Police are seeking the whereabouts of a young man who had been staying with the Rands a few days before the murder. Claiming to be a distant relative of Mrs. Rand, he arrived suddenly in the area and has since disappeared.

Second memo[]

Serial Killer Haigh Meets Grisly End

11 May 1962, West Sussex -- John Haigh, the serial killer on the run since early last year, has been found dead at a metal plating works. Haigh is held responsible for the cold-blooded murder of several pensioners, whom he robbed before placing the bodies in a container of sulfuric acid, thus disposing of the evidence.

The acid used in the crimes was stolen, leading the police to place factories in the area with stocks of sulfuric acid under surveillance. The suspect appeared at a plating factory in Horsham, and a struggle ensued. Haigh lost his balance and fell from a platform into a vat of acid, ironically meeting the same end as his victims.


  • "That's enough playing happy families! You make me sick!"
  • "How do you like the acid bath?"
  • "Want to join them? I hear the acid's lovely!"
  • "Aaah! Hot! Hot! Hot! Ah!"
  • "I found you!"
  • "There she is!"
  • "Prepare to die!"
  • "Damn it!"
  • "Stupid wench! You think I'll let you interfere?"
  • "None of your lip, little girl! You have your own destiny to accept!"
  • "You must die, Alyssa!"
  • "Hahahahahahaha!"



Corroder attacking Alyssa in Hard Mode.

  • His stalker theme is "Impending Destruction".
  • His modus operandi of killing his victims is inspired by the real John Haigh, who was known in Britain as the Acid Bath Murderer. Unlike in real life, Corroder in the game was never arrested, instead ironically falling into acid during a struggle with the police.
  • If Corroder is fought in Hard Mode, his nozzle will be replaced with a yellow spray bottle of acid.
  • In what the memo mentioned, Corroder died in 1962, which meant he was a Subordinate when he murdered the Rands in 1963. He also did not fake his name when he stayed with them.
  • He is the only killer whose area has no hiding places.
