I've been thinking about how the id Software universes could fit together, and I think there's a surprisingly elegant way to connect them without forcing every protagonist to be the same person.
The basic idea is this:
B.J. Blazkowicz, Ranger, and the Doom Slayer are all members of the same bloodline, fighting different stages of the same war across generations.
Before anyone says it: yes, I know this isn't canon. This is just a fun theory.
The First Chapter: B.J. Blazkowicz
Everything starts with B.J.
In Wolfenstein, he's fighting what appears to be a human enemy, but the Nazis are constantly experimenting with technology and occult forces beyond their understanding.
B.J. becomes the first member of the bloodline to confront something bigger than humanity itself.
He doesn't just stop a regime.
He prevents humanity from opening doors that should never be opened.
But some of that research survives.
Governments recover it.
Scientists study it.
The knowledge is never completely lost.
The Second Chapter: The Slipgate Program
Generations later, humanity develops Slipgate technology.
The events of Quake occur.
Scientists believe they've discovered advanced transportation and dimensional travel.
Instead, they accidentally expose humanity to an interconnected web of hostile realities.
This is where Ranger enters the story.
Unlike B.J., Ranger isn't fighting evil humans.
He's fighting something much older.
Much stranger.
The enemies of Quake aren't demons in the traditional sense. They're cosmic horrors, extradimensional entities, and beings that seem to exist outside normal reality.
Ranger defeats them and closes the portals.
Or so everyone thinks.
The Big Twist: Slipgates Become Hell Gates
This is where the theory gets interesting.
What if the dimensions discovered through Slipgate technology and the dimensions later known as Hell are actually connected?
Not necessarily the same place.
But part of the same dimensional network.
Humanity spends centuries experimenting with Slipgate technology.
Each generation pushes further.
Each generation discovers darker realms.
The corruption spreads.
The original science becomes mixed with religion, mythology, and fear.
Over time, people stop calling them Slipgates.
They start calling them Hell Gates.
The scientific explanation is forgotten.
The supernatural explanation takes over.
What Ranger knew as an interdimensional invasion eventually becomes what future civilizations know as a demonic invasion.
Ranger: The Forgotten Ancestor
One thing I love about this theory is Ranger's place in history.
B.J. becomes a war hero.
The Doom Slayer becomes a legend.
But Ranger?
Ranger becomes classified.
Buried.
Forgotten.
The government covers up what happened because the truth is too dangerous.
The existence of hostile dimensions remains secret.
Centuries pass.
His story fades into myth.
He's the missing link between Wolfenstein and DOOM.
The ancestor nobody remembers.
The Final Chapter: The Doom Slayer
Thousands of years later, the war reaches its final form.
A descendant of the Blazkowicz bloodline emerges.
The Doom Slayer.
By this point, humanity no longer understands the origins of the threat.
They believe Hell has always existed.
They don't realize that generations earlier, humanity itself helped establish contact through dimensional experimentation.
The Slayer isn't starting a war.
He's inheriting one.
B.J. fought the first signs.
Ranger discovered the true scale of it.
The Slayer is the one who finally ends it.
Why the Bloodline Works Better Than "They're the Same Guy"
A lot of crossover theories try to make every protagonist secretly the same person.
I think the bloodline idea is stronger.
Each hero represents a different stage of humanity's conflict with the unknown:
B.J. fights human evil.
Ranger fights cosmic evil.
The Slayer fights infernal evil.
The enemies evolve.
The battlefield evolves.
But the defining trait remains the same.
Every generation produces one person who refuses to surrender when everyone else does.
The Ending
Imagine the Doom Slayer discovering ancient records hidden somewhere in a forgotten UAC archive.
Most of the files are corrupted.
But one survives.
PROJECT SLIPGATE.
COMMANDING OFFICER: RANGER.
For the first time, the Slayer realizes the war against Hell didn't begin with Hell.
It began centuries earlier when another member of his bloodline stepped through a portal and fought the darkness waiting on the other side.
B.J. started the fight.
Ranger uncovered the truth.
The Slayer finished the war.
What do you guys think? Is Ranger the missing chapter that ties Wolfenstein and DOOM together? Or am I completely off the rails here? 😄
