What Is the Super Tyrant in Resident Evil 9?
The Super Tyrant is the mutated final form of Mr. X (T-00), a Tyrant-class bioweapon that has been a recurring threat in the Resident Evil series since RE2. In Resident Evil 9: Requiem, Mr. X reappears during Leon's Raccoon City flashback sequence and undergoes a dramatic mutation into the RE9 Super Tyrant during the climax of the RPD chapter.
Unlike his stalker form earlier in the chapter, the RE9 Super Tyrant is a dedicated arena boss fight with three distinct phases. Key characteristics include:
- Health pool: Approximately 15,000 HP across all phases (Professional difficulty scales to 22,000 HP)
- Weak point: Exposed heart on the left side of the chest, visible after Phase 1
- Resistances: Immune to flashbang stun, resistant to shotgun stagger in Phase 3
- Vulnerability: Takes 2x damage from magnum rounds and explosive weapons hitting the weak point
🚨Point of No Return
The Super Tyrant boss fight begins immediately after the RPD rooftop cutscene. There is no opportunity to return to the safe room or item box once the fight starts. Make sure your loadout is prepared before taking the elevator to the rooftop. See our RPD Orphanage walkthrough for the full chapter guide.
How to Beat the RE9 Super Tyrant: Phase-by-Phase Guide
Phase 1: RPD Rooftop (100% - 60% HP)
The first phase of the RE9 Mr. X boss fight takes place on the RPD building rooftop. The Super Tyrant uses slow but devastating melee attacks. This phase teaches you his basic attack patterns.
Attack patterns and counters:
- Overhead Slam - The Super Tyrant raises both fists above his head. Dodge left or right 0.5 seconds after the windup starts. Punish with 2-3 handgun shots to the chest.
- Charging Rush - He lowers his shoulder and charges in a straight line. Dodge perpendicular to his path. He staggers against the rooftop railing, giving you a 4-second damage window.
- Backhand Sweep - A wide horizontal sweep at close range. Step back out of range rather than dodging to the side. The sweep has deceptive range.
Recommended weapons for Phase 1:
Use the handgun or shotgun to conserve magnum ammo for later phases. Aim for the chest area. After dealing approximately 40% of his total health in damage, the Super Tyrant staggers and a brief cutscene shows his chest splitting open to reveal the exposed heart.
| Weapon | Damage per Hit | Phase 1 Rating | Notes |
|---|---|---|---|
| SG-09 R Handgun | 180 | Good | Reliable, conserves ammo for later phases |
| W-870 Shotgun | 650 | Great | Effective at close range after dodge windows |
| Lightning Hawk Magnum | 2,400 | Save it | Reserve for Phase 2 and 3 weak point shots |
| Hand Grenade | 3,000 | Great | Use during stagger windows for maximum damage |
| Rocket Launcher | 10,000 | Excellent | One shot removes an entire phase (if you have one) |
Phase 2: Mutation (60% - 25% HP)
After the Phase 1 cutscene, the RE9 Super Tyrant mutates further. His right arm transforms into a massive blade, and his attacks become faster. The exposed heart on his left chest is now the primary weak point, and hitting it deals double damage.
New attack patterns:
- Blade Lunge - A fast forward thrust with the mutated arm. Dodge to the right (away from the blade) with tight timing. The window is roughly 0.3 seconds.
- Three-Hit Combo - Slash, slash, overhead slam. Dodge the first slash, then continue dodging in the same direction for the full combo. Do not attempt to punish between hits.
- Ground Pound - The Super Tyrant leaps and slams the ground, creating a shockwave. Sprint away from the impact zone. The shockwave extends approximately 5 meters.
Strategy for Phase 2:
Switch to the magnum and aim exclusively at the exposed heart. Each magnum round to the weak point deals approximately 4,800 damage (2x multiplier). Three to four well-placed magnum shots can carry you through this entire phase. Use hand grenades during the recovery window after his three-hit combo.
💡Parry for Massive Damage
The Super Tyrant's Blade Lunge can be parried with precise timing. A successful parry staggers him for 5 seconds and briefly enlarges the heart weak point, making it easier to hit. This is the highest-risk, highest-reward strategy in the fight. Practice your parry timing before this encounter.
Phase 3: Final Stand (25% - 0% HP)
The final phase of the RE9 Super Tyrant fight is a desperate battle. Mr. X becomes significantly more aggressive, chaining attacks with shorter recovery windows. The rooftop begins to collapse, reducing the available arena space.
Critical changes in Phase 3:
- The Super Tyrant gains a Regeneration ability, slowly recovering HP over time
- His attacks have increased tracking, making diagonal dodges necessary
- Shotgun staggers no longer work; he has hyper-armor on most attacks
- The exposed heart pulses with red light, indicating when he is about to use his strongest attack
The Final Attack - Impaler Charge:
At 10% HP, the Super Tyrant channels his strongest attack: the Impaler Charge. This is a one-hit kill if it connects. When you see the heart glow bright red and hear the audio cue (a deep roar), immediately sprint perpendicular to his facing direction. After the charge misses, he is stunned for 8 seconds. Unload everything you have into the heart.
If you run out of ammo:
There is an ammo crate on the north side of the rooftop that spawns during Phase 3. It contains handgun ammo and one shotgun shell box. The RE9 Super Tyrant will not attack while you are picking up items from this crate, giving you a brief safe window.
Why the Super Tyrant Is One of RE9's Hardest Bosses
The RE9 Super Tyrant ranks among the most challenging encounters in Resident Evil 9 because it tests your mastery of Leon's third-person action combat system. Unlike stealth-focused bosses such as The Girl, the Super Tyrant demands precise dodging, resource management, and knowledge of when to use each weapon type.
The fight also serves as a milestone that validates your preparation throughout the Raccoon City chapter. Players who have been conserving magnum ammo and grenades will find the fight considerably more manageable than those who spent resources freely.

Frequently Asked Questions
What is the best weapon against the RE9 Super Tyrant?
The Lightning Hawk Magnum is the single best weapon against the RE9 Super Tyrant due to its high base damage and the 2x weak point multiplier on the exposed heart. Three to four magnum shots to the heart in Phase 2 can skip most of that phase entirely. However, the shotgun is the most efficient weapon for Phase 1 when no weak point is exposed.
Can you skip the Super Tyrant fight?
No. The RE9 Mr. X boss fight is a mandatory story encounter in the Raccoon City chapter. There are no alternative routes or sequence breaks that allow you to bypass this fight.
How many healing items should I bring?
Bring at least 3 First Aid Sprays or 5 mixed herbs for Standard difficulty. On Professional difficulty, bring everything you have. The Super Tyrant's attacks deal approximately 40% of Leon's max health on Standard and 65% on Professional. There are no healing pickups during the fight itself.
Does the Super Tyrant have a time limit?
There is no hard time limit. However, in Phase 3, the Super Tyrant's regeneration ability means you need to deal damage faster than he recovers. On Professional difficulty, his regeneration is approximately 100 HP per second, so prolonged fights become increasingly difficult. Aim to finish Phase 3 within 2-3 minutes for the best results.
