  • Backstory: Former lead researcher at Umbrella’s Eastern European facility, now working for a rogue BSAA faction
  • Appearance: Tall, gaunt, wears a hazmat suit with a cracked visor (shows his face after Chapter 9)
  • Motivation: Believes Mold can evolve humanity, but his experiments create monsters
  • Boss fight: Chapter 11 — he transforms into a 20-foot Mold beast with three phases; phase 2 requires you to destroy 4 sacs on his back (each has 800 HP) **The Tyrant Mk. III**
  • Encounter: Chapter 3 (Leon) and Chapter 8 (Jill)
  • Differences: Leon fights a faster version; Jill faces one with armor plating
  • Weakness: Electroshock — use the Tesla coil in the lab to stun it for 5 seconds
  • HP: 4,500 (Leon’s fight), 6,200 (Jill’s fight) **Mold Lurkers**
  • Common enemy in Rose’s chapters
  • Behavior: Burrow underground, then surface to attack
  • Weakness: Shotgun blast to the head (instant kill if close range)
  • Loot: Drop Mold samples (crafting material for Rose’s upgrades) ### Character Relationships and Lore
  • **Leon and Jill** never met before this game — their interactions are professional but tense (Jill distrusts the DSO after the events of RE6)
  • **Ethan’s flashbacks** reveal he was infected with Mold before RE7, which is why Rose has powers
  • **Chris’s betrayal** is a red herring: he’s actually working undercover to expose Grimes
  • **Mia Reeves** is the daughter of a BSAA scientist who died in the Raccoon City outbreak — she’s seeking revenge ### Frequently Asked Questions **Q: Can I play as Chris Redfield in Resident Evil 9?** A: No. Chris is an NPC throughout the game. He appears in cutscenes and provides support, but you cannot control him. This disappointed some fans, but his role in the story is significant. **Q: How many characters are playable in RE9?** A: Five — Leon, Jill, Ethan (flashback only), Rose, and Mia. That’s the largest playable roster since Resident Evil 6, but each character has a shorter campaign (around 4–6 chapters each). **Q: Is there a character with the best abilities?** A: It depends on your playstyle. Leon’s parry is great for aggressive players, Jill’s lockpick unlocks valuable loot, Rose’s Mold vision makes exploration easier, and Mia’s drone helps with stealth. For combat efficiency, Leon is the strongest. For puzzle-solving, Jill is essential.
