Earth-89947 Timeline

The Diverging Points of Giant-Size Fantastic Four #2

 Earth-616 Willie Lumpkin is tricked by Tempus and travels through a time
in the 1920's prior to Elliot Ness beginning a case to stop Al Capone and 
his mobsters.  Lumpkin then joins with that era's Chicago mobsters and provides 
them with information which enables them to corner the Stock Market. After he 
has gone back to Earth-616, the mobsters gain control of society.

An Untouchable View of Excalibur #44

 Elliot Ness and his "Untouchables" fail to bring Al Capone and his mobsters 
down, with the result that the eighteenth amendment to the U.S. Constitution, 
which prohibited the sale of "intoxicating liquors," is never repealed. 
Capone and other members of organized crime continue to gain money and power 
by bootlegging alcohol and setting up casino gambling empires.  Eventually,
even murder is considered legal worldwide.

A Powerful Gangsta in a Gangsta World

Brius Capone, Al Capone's grandson, begins his career as Enforcer Capone after a visit from Merlin and Roma. Enforcer Capone then travels to Otherworld as a jury member of Earth-616 Captain Britain's trial. He along with other jurists declare him to be guilty. [The real identity of Enforcer Capone is named by Lenny Carlson; his origin is based on Captain Britain's origin]

Sliding the Greatfellas Times

 On Sliders television episode "Greatfellas", the Sliders team of
Earth-Prime slides into this world and discovers this Earth's results. The
San Francisco skyline now looks similar to Las Vegas, former American
President (and now California Governor) Ronald Reagan dismantled the
federal government during his term at the office, in an attempt to return 
autonomy to the states, with the result that California, Nevada, Washington 
and Oregon seceded from the Union in 1997. Nevada is controlled by the 
Dabell family while the Greenfeld Family rules California, Rembrandt Brown 
of this Earth is FBI Deputy Director and head of group of agents known as 
"The Incorruptables" to carry Elliot Ness' legacy, and former government 
informant Mel Torme (on Earth-Real, he's the father of Tracy Torme who co-
created Sliders television series) is a country & western singer who's 
currently on tour with Wynonna Judd. The Sliders have somehow disrupted 
the wedding with a member of the Greenfeld Family and a member of the Dabell 
family and let the mob war to go on until Rembrandt of this world finds a way 
to stop it. 
 Note that on the production script of that episode, gambling, drugs and gun 
possession are also illegal on this world.
 As for this Earth's media properties (other than Mel Torme and Wynonna
Judd), Casino, Goodfellas, and the Earth's sequel flick Return of
Greatfellas are shown to the Disney Channel along with other
gangster-gelated programs, and some public phones are actually an
amalgamation of phones and slot machines.


NOTES:

From Lenny Carlson: I include Sliders "Greatfellas" episode as part of the 
profile to expand some information of this Earth.  See TV Tome, 
Earth Prime: Sliders Episode Guide and EP.COM: Travelogue.

From John McDonagh: Night Raven was active in the 1920's, sometimes in
Chicago or New York.

Elliot Ness was in Amazing Spider-Man #200 in a fb. He was shown arresting 
Dutch Malone.

Other than that, another organized crime dominated Earth was seen in
the 1980's or 1900's Black Terror limited series by Chuck Dixon. On
that world, Capone was not arrested, and as a result, organized
crime gained an appreciably stronger foothold.  [SubNote from Mikel Midnight:
it's a shame it's a Nedor character, or else I'd nab this for the timeline.  
If it were Ace, Centaur, Fox, or Holyoke the Marvel multiverse might 
conceivably have a claim on it.]
