He’s the giant in the trench coat. The one who ruined your night in Raccoon City with those heavy, rhythmic boots hitting the floorboards of the R.P.D. Most of us spent half of Resident Evil 2 just trying to outrun the T-003 Tyrant, but everything changes when the self-destruct timer starts ticking. Suddenly, the "gentleman" in the fedora is gone. In his place? A screaming, clawed monstrosity. Mr. X final form isn’t just a boss; it’s the result of a bioweapon’s safety brakes being ripped off.
Honestly, the transformation is kinda tragic if you think about the science. Umbrella didn't put that coat on him for style. It’s a Power Limiter. Its literal job is to keep the T-Virus from mutating the host into an uncontrollable mess. When that coat burns off in the NEST laboratory explosion, the "Super Tyrant" is born.
The Super Tyrant: What’s Actually Happening?
When you face the Super Tyrant on that rising platform, you aren't just fighting a bigger version of the same guy. You're looking at a biological runaway train. Without the limiter, his muscles swell until they literally tear through his skin. One of his arms becomes a massive, jagged claw that can cover half the arena in a single swipe.
You’ve probably noticed the glowing, exposed heart. That’s the classic Tyrant weak spot. In this final form, the metabolism is so high and the mutation so aggressive that the heart has to enlarge and protrude just to keep the blood pumping to those massive new muscles. It's a design flaw, basically.
Why He’s Faster Than You Remember
In his base form, Mr. X is slow. Purposefully slow. He stalks. But the final form? He sprints. He lunges. He has this one-hit-kill charge that has ended more speedruns than I care to count.
Leon Kennedy is just a guy with a handgun (at first), and this thing is a ten-foot-tall wall of meat and anger. The game shifts from a "hide and seek" horror dynamic to a "don't let him touch you or you're a pancake" action thriller.
Surviving the Final Stand (The Mechanics)
Most players think they need to dump every single bullet into his heart to win. You don't. The fight is actually a timer.

Basically, you’re just trying to stay alive for about three and a half minutes. If you deal enough damage to his heart, you can "stagger" him, which actually speeds up the hidden timer. But if you're low on ammo? You can literally just run in circles.
- The Roar: When he roars and pulls his claw back, he’s about to end your run. This is the "Uh-oh" move.
- The Stun: You need to save your heavy hitters—the Magnum or Frag Grenades—for this specific moment. If you don't stun him during the roar, the screen goes gray.
- The Rubble: Rocks will fall from the ceiling. Use them. They won't stop him forever, but they buy you three seconds of breathing room.
The Ada Wong Factor
You can’t actually kill him with normal guns. It’s a lore thing. Tyrants have this insane regeneration. You can poke holes in him all day, and he’ll just keep coming. You need the Anti-Tank Rocket Launcher.
Ada drops it when the timer is almost out. Once you pick that up, the "boss fight" is over. One or two rockets (depending on your difficulty) will literally blow him into pieces. It’s a scripted, cinematic end to a relentless pursuit.
Remake vs. Original: The Big Changes
If you played the 1998 original, the final form felt a bit different. Back then, he was a bit more "blocky" and his movements were stiffer. The 2019 remake turned him into a much more fluid, terrifying athlete.
In the original, the Super Tyrant was also a bit more "generic" in his look. The remake added the detail of the burnt, melted skin and the much more prominent exposed heart. It makes the mutation feel like a painful, desperate process rather than just a "level up."
How to Handle Mr. X Final Form Like a Pro
If you want to get that S+ rank, you can't be messing around on the elevator.
- Hoard Grenades: Save every single hand grenade you find in the lab. Throwing one immediately staggers him and shaves seconds off the clock.
- Left is Best: Generally, stay to his left (your right). His massive claw is on his right side. Most of his wide sweeps start from there.
- Flashbangs are Life: If you’re out of ammo and he’s charging his insta-kill, a flashbang will cancel the animation.
The Mr. X final form represents everything Umbrella stands for: power without control. He’s a perfected soldier who becomes a monster the second he’s allowed to be "himself."
When you finally land that rocket and see him disintegrate, it’s not just about winning the boss fight. It’s about finally getting some peace and quiet after hours of those damn footsteps.
What to do next
To make your next encounter easier, go back to your previous save and ensure you have at least three Frag Grenades and six Magnum rounds specifically for the elevator. Don't waste your Flamethrower on him—it’s borderline useless against his final form's high-speed movement. Focus entirely on the heart to trigger the staggers, and the Anti-Tank Rocket Launcher will appear much faster than if you just played defensively.
