!!'''Henry Townshend'''
-> '''Voiced by:''' Eric Bossick

[[caption-width-right:300:''[-Five days ago... That's when I first had the nightmare. I haven't been able to get out of my room since then-]'']]

Henry wakes up one morning to find that he's been trapped in his own apartment.

[[spoiler:Henry is number 21 of the 21 Sacraments, "The Receiver of Wisdom", the final stage of Walter's ritual to "awaken his mother"]].

* ActionSurvivor
* TheCallKnowsWhereYouLive: Literally. Or, more specifically, "The Call Wants Inside Where You Live".
* CatchPhrase: "What the hell?!"
** Henry is infamous for "What the hell?", even though he says it [[NeverLiveItDown only four times throughout the game]], or (for those keeping track at home) only one fewer time than [[SilentHill1 Harry Mason]] describes his daughter to people as "just turned seven last month, short, black hair" And, one presumes, this is only because he ran out of people to ask.
** He says it a lot more when inspecting items and environments.
* DeathGlare: Henry might be known for not showing much reaction to things, but check his facial expression at the start of the last boss fight. Dude looks pissed.
* DullSurprise: What sets him apart from all other ''Franchise/SilentHill'' protagonists. You know it's bad when a random wall can, quite literally, be expressive in a greater range than he manages. Seriously. A wall.
* TheEveryman: WordOfGod is that he is supposed to invoke the image of an "average" man.
* FlatCharacter: Even getting the better endings, he doesn't do an ''awful'' lot of growing within his character arc, all things considered. Accusing him of this is fairly common, as a result. This rather sets him apart from most protagonists for the series, as it's like he blundered in by total accident with little to learn. [[spoiler: Which turns out to make a lot of sense: the game is about how screwed up ''Walter'' is, and, is therefore, not primarily focused on Henry's issues.]]
* TheHermit: He'd done a wonderful job of isolating himself from much of the world even before he got locked into Room 302.
* TheNeedless: It's not elaborated on, but it seems that Henry doesn't need to eat as long as he's in Room 302. Examining his stove at different times will make him comment that he should be hungry, but isn't.
* {{Hikikomori}}: The game is an odd exploration of this trope. He was a reclusive agoraphobic before the events of the game, but ''[[InnSecurity during]]'' the game...
* IronicHell: An agoraphobic who can't leave his apartment. Gotcha!
* {{Kuudere}}: Henry shows a lot of willingness to help others but rarely expresses the fact. Justified in that he never really expresses much of [[{{DullSurprise}} anything]].
* ProtectThisHouse: Along with [[spoiler:escorting Eileen through Walter's Otherworlds]], this also becomes one of the things he needs to do to survive.
* TheQuietOne: And, that's putting it mildly. Even murder doesn't get him to say much above a quiet speaking voice. Or more than a few words.
* ShrinkingViolet: Henry is mentioned by the others as very shy, so it's not seen to be too strange when he doesn't emerge from his apartment for days on end.
* TheStoic: Whatever emotions Henry may have, he certainly doesn't express them very strongly, leading to many {{Dull Surprise}}s.
* [[spoiler:SupportingProtagonist: Henry is the focal character, but the story really revolves around Walter; Henry is just in the wrong place at the wrong time]].

!!'''Eileen Galvin'''
-> '''Voiced by:''' Anna Kunnecke

[[caption-width-right:300:''[-Hope my luck changes before the party.-]'']]

Henry's next-door neighbor. She's upbeat and perky.

[[spoiler:Of the 21 Sacraments, she is 20/21, "The Mother Reborn". She should have been killed by Walter, but he was stopped by the mysterious boy (Young Walter). She still suffered many injuries and was sent to the hospital, but ended up being sucked into the dark world again; this time, Henry managed to get to her before Walter did, taking her under his care and protection. She cannot die, but she does suffer damage, which affects her survival at the game's end]].

* ArtificialStupidity: [[spoiler:During the extended escort mission, she becomes more or less aggressive depending on what weapon she's holding]]. This would be fine, if she didn't insist on [[spoiler: attacking Walter (who is invincible), which if allowed to go on long enough will result in her damage level skyrocketing as he beats her up. The only way to get her to stop is to take her weapon away, forcing her to follow Henry as closely as possible]].
* BandageBabe: Emphasis on the "babe", especially with the Nurse outfit on.
* CoveredInScars: [[spoiler:During the EscortMission phase, she's still severely scarred from her encounter with Walter. This can get worse as you keep playing unless you take good care not to let her get hurt]].
* DistressedDamsel: [[spoiler: Injury and being sucked into the dark world; distressing indeed.]]
* DamselOutOfDistress: Can hold her own against enemies very well, even despite her severely injured state. Especially if you let her cut loose with an ''infinite-ammo'' submachine gun! [[AwesomeButImpractical Although the recoil will eventually take its toll on her...]]
* [[spoiler: EscortMission]]: [[spoiler: Her presence turns the whole second half of the game into one]].
* GirlNextDoor
* GreenEyes
* JigglePhysics: Only if wearing the Nurse outfit.
* MinidressOfPower: Deconstructed. A skimpy dress worn by the star of Walter's snuff fantasies.
* NoGoodDeedGoesUnpunished: Gets tangled up in Walter's fantasies by virtue of being kind to him as a child. He even decides to pass it on to Henry, offering the doll she gave him as a child.
* ParentalSubstitute: [[spoiler:Walter seems to think of her as this in a way, thus she is "The Mother Reborn". [[WildMassGuessing Fans speculate that she ends up pregnant of a reborn Walter in the "Mother" ending]].]]
* PinkMeansFeminine
* [[spoiler: {{Protectorate}}]]
* SamaritanSyndrome: Lying on the floor, bleeding to death, with "20121" carved into her back, Eileen's first thought is to speak calmly to the boy and urge him to run away.
** Her soft-heartedness toward [[spoiler:Little Walter]] lands her in hot water, later.
* {{Stripperiffic}}/NaughtyNurseOutfit: Unlockable on a second playthrough.
* VideogameCaringPotential: Her condition is one of the two variables that affect what ending you will get.

!!'''Frank Sunderland'''

James Sunderland's father and the superintendent of the South Ashfield apartments.

* ContinuityNod: To ''Silent Hill 2'', of course.
* ChekhovsGun: [[spoiler:He offhandedly mentions to Eileen while Henry's listening in that he keeps Walter's umbilical cord in his room, which for some reason he can't bring himself to get rid of]].

!!'''Walter Sullivan'''
-> '''Voiced by:''' Dennis Falt

[[caption-width-right:300:''[-My name's Walter. Walter Sullivan. It's time to complete the 21 Sacraments.-]'']]

A supposedly dead serial killer -- so what is he doing still stalking the halls of Ashfield Heights, killing (or attempting to kill) everyone he comes across?

* AndShowItToYou: His first ten victims for his 21 Sacraments had their hearts removed as well.
* AscendedExtra: Briefly mentioned in a newspaper article in Silent Hill 2.
* AxCrazy
* BadassLongcoat: A blue raincoat.
* BarbarianLongHair
* BlondGuysAreEvil
* BloodIsTheNewBlack
* BigBad
* CallingCard: Ripping out hearts (only for his first ten victims) and carving numbers into the bodies.
* ChainsawGood: He's armed with a pistol and a chainsaw the first time you meet him. [[DemonicSpiders Neither option is pleasant.]]
* CrucifiedHeroShot: Inverted -- [[spoiler:His corpse is]] strung up and mounted on a giant metal cross.
* [[spoiler:DeadAllAlong]]: The Walter Sullivan you encounter throughout the game is [[spoiler:just a projection]]. The real Walter's [[spoiler:moldering corpse is hidden behind a false wall in Henry's apartment]].
* DissonantSerenity: The most laid-back character the series has produced yet.
* DualWielding: Guns, and that's when he's most annoying.
* EvenBadMenLoveTheirMamas: Even serial killer Walter loves his mommy, [[spoiler:the apartment you're stuck in]]. In fact, his love for his mommy is his primary motivation.
* EvilLaugh: Attempts to cause Walter injury merely amuse him.
** He may do it while[=/=]before attacking.
* FamousLastWords: "Mom?" Well, what else?
* FauxAffablyEvil: Behaves this way to Henry. One would almost think it's a ''privilege'' to be the last of Walter's twenty-one victims.
* FiringOneHanded: And holding a long steel pipe in the other.
* FreudianExcuse: Walter's got one. Or a dozen.
* FutureMeScaresMe: The scene with Little Walter meeting his future self. Little Walter doesn't quite grasp the implications, but the player does.
* HeManWomanHater: Has issues with the fairer sex, evidenced by his brutal beatdown of Eileen, as well as Cynthia's bloody death. Also makes a pastime of mutilating female cadavers, which rise again as scary ol' giantesses.
* HumanoidAbomination: [[spoiler: His ghost is highly reminiscent of [[Series/TwinPeaks BOB]] in both [[WildHair appearance]] and [[AxCrazy mannerisms.]]]]
* TheIllegible: Walter's personal diary is scattered throughout the Forest area on stones; however, Henry is unable to make out several passages due to the script being very childish and scrawling. Eileen is able to translate them when you return later.
** When he started killing, police were unsure why he was carving numbers like "01121" into his victims. It turns out that the middle character was actually a slash -- "01/21". He was counting his victims down.
* ImplacableMan: Being that he's [[spoiler:a ghost himself]], Walter Sullivan absolutely ''[[PunctuatedForEmphasis Can. Not. Be. Killed.]]'' You can knock him down or pump him full of lead, but he'll always rise back up again.
* ImprobableWeaponUser: A lot of his [[TenLittleMurderVictims 21 Sacraments]] kills were with odd weapons. For example, the sporting goods shopkeeper he killed with a golf club.
* [[KingMook King]] EliteMook: As far as gameplay goes, he's a glorified Victim Ghost [[spoiler: until the FinalBoss fight, and only after impaling the 8 spears into his body]].
* MonsterSobStory: He just wants his mother!
* MyDeathIsJustTheBeginning: Well, actually not the beginning, but [[spoiler:the halfway mark of his 21 Sacraments]].
* NiceJobFixingItVillain: [[spoiler:Of all the "Givers of Wisdom" that could have taken up residence in his beloved Room 302, it had to be a very diligent and very prolific writer. If Joseph hadn't done the research on Walter, the Cult, and particularly the Crimson Tome, Henry may as well just serve Eileen to Walter on a platter]].
* OnceKilledAManWithANoodleImplement: [[spoiler:Killed himself]] in prison with a [[FunnySpoon serving spoon]]. Ouch.
* PermaStubble
* PerpetualSmiler
* PoorCommunicationKills: His young and unschooled mind confused "Mother is in Room 302" with "Mother ''is'' Room 302", birthing his bizarre obsession.
** Not exactly. It's implied that [[SilentHill1 Dahlia Gillespie]] meant for him to think that and perform the 21 Sacraments, as an alternative method for summoning God.
* StepfordSmiler: He is Type C.
* PsychopathicManchild: [[spoiler:In fact, as close to a literal example as it gets]].
* RiseFromYourGrave: In the Forest World, Henry uncovers his empty plot. [[spoiler:Walter's ghost dug up his body and installed it in Room 302]].
* SerialKiller
* ShroudedInMyth: Authorities are baffled at how this guy continues killing when he's [[spoiler:already dead]].
* ThanatosGambit: Walter [[spoiler:killed himself]] after being apprehended. He rose again [[spoiler:as ghost and dug up his own corpse]], which he then walled up inside Henry's apartment.
* WouldHurtAChild: The Locane twins. Interestingly, they are the only victims who appear as monsters (Twin Victims) rather than ghosts.
* UsedToBeASweetKid: Before The Order got their mitts on him.
* [[spoiler:TheVillainMakesThePlot]]
* WoobieDestroyerOfWorlds: In the end Walter is just a boy who wants his mommmy

!!'''Cynthia Velasquez'''
-> '''Voiced by:''' Creator/LisaOrtiz

A mysterious flirty woman whom Henry encounters in Subway World after he first enters the hole in his apartment. [[spoiler:She's Walter's 16th victim, representing "Temptation"]].

* AllThereInTheManual: Unlike the other characters who have some connection to Walter in some way revealed later in the game, the only way to find out how she connects in all this is in the Other Crimson Tome, which is not in Silent Hill 4.
* CampingACrapper
* KillTheCutie
* LetThemDieHappy: "It's okay...it's just a dream."
** This makes her [[spoiler:revival as a ghost]] more tragic.
* SpicyLatina
* [[spoiler:StringyHairedGhostGirl: Comes back as one]].
* {{Stripperiffic}}: Her normal clothes are quite bold, and on a second playthrough you can unlock an even more revealing costume.
* [[spoiler:SuperPersistentPredator: Her ghost is the most persistent of the four boss ghosts (not counting Walter). If she is not pinned down, she will show up more often (starting at Building World) to harass and attack the player.]]

!!'''Jasper Gein'''

A guy with a stutter who's obsessed with the paranormal. Henry meets him in Forest World after Cynthia dies. [[spoiler: Victim 17/21, "Source", in Walter's 21 Sacraments]].

* HillbillyHorrors
* [[spoiler: ManOnFire: Jasper is ablaze even in (un?)death, because said man set himself on fire as part of the 21 Sacraments.]]
* MeaningfulName: His last name is probably a reference to Ed Gein.
* [[spoiler: PlayingWithFire: While his ghost doesn't shoot fire, he himself is immolated. As a result, it gets hard for the player to be near him to deal melee damage because of his flames. Plus, he hits harder.]]
* SpeechImpediment: [[spoiler: Except when he dies]].
* TrademarkFavoriteFood: Jasper Gein sure loves that chocolate milk.

!!'''Andrew [=DeSalvo=]'''

An obese man Henry comes across while the former is trapped in the Wish House's prison. [[spoiler:Victim 18 of 21, "Watchfulness"]].

* {{Acrofatic}}: Later.
** FatBastard
* AssholeVictim: Not to Henry, per se. However, when the player re-enters the Water Prison and you find out what he did, it's hard to really have any sympathy for his death.
* [[spoiler:ArcSymbol: His Placard is reminiscent of Walter's past, on how Andrew kept watching him and a special eye out to beat him and his friends whenever he wanted. The tables were turned when Henry first meets Andrew in the Water Prison, whereas Walter was watching him in the center of the prison.]]
* KarmicDeath: [[spoiler:Andrew runs the very prison that he was trapped in. You find out that the children were often forced to drink water with leeches in it. Henry eventually finds him drowned in the kitchen's back room, with "18/21" carved on his stomach]].
* IronicNurseryTune: [[spoiler: Andrew sings a song that is about the ritual of the holy assumption.]]
* MeaningfulName: He is most likely named after Albert [=DeSalvo=], the man suspected of being the Boston Strangler.
* [[spoiler:StockMonsterSymbolism: Andrew is the guard that beat up Walter in his childhood. As a result, he is killed by Walter. Later, when he returns as a ghost, Henry is going to have to pin him down with the Sword of Obedience to get his key. Essentially, Henry is sticking it into the fat pig that Walter always wanted to do. Because you have to beat him down (he's the only ghost you have to defeat and pin down in order to proceed), and you're in Walter's world to do it, it's also means that you are roleplaying as Walter beating him up.]]

!!'''Richard Braintree'''

A JerkAss who terrorized his neighbors, Richard's response to falling into the Otherworld is to wave his gun around, [[spoiler: fat lot of good that does him. Victim 19 of 21 -- "Chaos".]]

* AssholeVictim: More explicitly so than Andrew.
* [[spoiler:ArcSymbol: Richard's placard, Chaos, isn't quite fitting of a man who loved order so much until you put it together with Walter's past. Richard was the first time Young Walter had ever been scared of anything, and it was in fear of Richard that Walter stayed away from him at all costs, even when Walter went to visit his "mother". Richard introduced Chaos to Walter's little world.]]
* ChildHater
* [[spoiler:DyingForSymbolism: Richard is murdered in the electric chair, reminiscent of how criminals are put to death. Walter had this death in mind for him based off of witnessing Richard "skinning" Mike (Young Walter thought that Richard killed him by skinning him alive), and thinking that he killed him.]]
* [[spoiler:ElectricTorture[=/=]CruelAndUnusualDeath: How Richard bites the dust.]]
* HairTriggerTemper: It would be easier to list the things that ''didn't'' piss him off. Barring Eileen and the superintendent, he wasn't too popular with the other roommates.
* {{Jerkass}}
* PsychoElectro: By virtue of his [[spoiler:CruelAndUnusualDeath]].
* RevolversAreJustBetter: Henry can gain it later, and it's quite a piece of power. Ammo, of course, is rather rare for it though.

!!'''Joseph Schreiber'''

A journalist introduced back in ''VideoGame/SilentHill3'' as a writer of a magazine article regarding Silent Hill's Wish House, where Walter was raised. In this game, he's the former resident of Room 302 before Henry moves in. [[spoiler:He's also Walter's 15th victim, representing "Despair", who's supposed to serve as a guide for Henry, "The Receiver of Wisdom"]].

* [[spoiler:AndNowForSomeoneCompletelyDifferent]]: A retroactive case. [[spoiler:He's the PlayerCharacter in the prologue of the game, suddenly finding himself in a haunted version of Henry's Room 302]].
* BadassBaritone: When he speaks in Room 302 of the Past, he addresses Henry in a very deep, booming and echoing voice.
* BenevolentPrecursors: [[spoiler:As convenient as it is that he's a significantly prolific writer, the more he learns about Walter, the more he realizes his role as the giver to the coming "Receiver of Wisdom". His later notes are the most specific and most helpful to the player]].
* FallenHero: Though not an evil one.
* ContinuityNod: From ''VideoGame/SilentHill3'', in the same way that Walter Sullivan and Frank Sunderland are from ''VideoGame/SilentHill2''.
* MeaningfulName: His last name is Schreiber, which is German for writer, and he's a journalist.
* MrExposition: When Henry finds him in Room 302 of the Past, he explains Walter's backstory, as well as the means to stop Walter. He's also the writer of the Red Diary excerpts which Henry keeps finding slipped under his front door.
