Dark Heresy builds its party from an Inquisition retinue rather than a generic adventuring group. Every companion has a combat archetype and a role in investigations; Owlcat’s beta overview says each one also contributes specialist knowledge to cases.
The core eight
Cogg — Ogryn Warrior
A Bone’ead Ogryn (Conscript O-118-B) who works as a melee tank and mobile cover. Cogg is the straightforward front-line option: high durability, heavy hits, and the body-part targeting system rewards getting close. Voiced by Jonathan Cox.
Haymar Devos — Catachan Soldier
A Catachan Devils veteran built around burst fire and suppression. Haymar is the ranged damage baseline: if you want a straightforward shoot-first companion, this is the one. Voiced by Aaron Sinn.
Ra’akhti — Kroot Operative
A Kroot scout and exile known as “Inedible” who can sense memories by eating flesh. Ra’akhti fills the precision/assassin role, with a Pech’ra familiar called Yuka. Voiced by Rhiannon Moushall.
Saro — Sanctioned Psyker
A pyromancer with a unique rhyme mechanic. Saro is the beta’s dedicated psyker companion and the clearest look at how warp powers are built. Voiced by Stephen Spencer.
Discordance — Pariah
A Pariah whose soulless nature creates an anti-psyker zone. Discordance is the counter to psychic enemies and warp phenomena, and her presence changes how encounters with psykers play out.
Laarthyr Cairnareth — Aeldari Way Seeker
An Aeldari Corsair and Way Seeker, a psyker/melee hybrid archetype shown in the alpha preview. Laarthyr is the xenos wildcard of the roster. Voiced by Chris Sharpes.
Aspyce Chorda — Rogue Trader
A Lord Captain from a Scintillan noble dynasty, stranded in Calixis by the Great Rift. Aspyce is a noble/combat hybrid whose presence opens doors and creates problems in equal measure; the official post frames her as someone the Inquisition watches with suspicion.
Touma Ortos — Officer
An acolyte who fights as an Officer. Touma is the party commander and the natural support slot: buffs, action economy and morale. Owlcat describes Touma’s motives as unclear, which is a hook for the story.
The two extra beta companions
These appear in the closed beta lineup but are not on the eight-name release roster:
- Epione Spes — a Chirurgeon/Medicae Soldier. She is the healing and support specialist, built around Tactical Movement and medicae abilities. Voiced by Brittany Chanel.
- Hypatia — named in the beta overview. Details are thin; treat her as beta-only until launch.
The Servo-Ossuarium is a voiced servo-skull helper, not a regular companion.
How companions fit investigations
Owlcat’s investigation design gives companions two jobs:
- Combat archetype — what they do in turn-based fights.
- Specialist knowledge — what they notice in interviews and crime scenes. The beta lets you swap companions between investigation steps, so bringing the right specialist is part of solving a case.
That makes roster composition a two-sided decision: combat balance and investigative coverage. For how the case structure works, see investigation.
Who to bring
Until launch, the safest beta-based advice is:
- Cogg for a durable front line and body-part damage.
- Haymar for reliable ranged damage and suppression.
- Ra’akhti when you need precision and a skill-focused operative.
- Saro or Laarthyr when psychic damage is the answer.
- Discordance when enemy psykers are the problem.
- Touma when the party needs more actions and morale.
- Aspyce when the story needs a noble’s authority.
- Epione when sustain matters more than raw damage.
Companion balance is beta-based and will change at launch; we will update this page when the release build is out.
