let's start with the simplest ones.

batman - Should have all of his skin covered by his costume. none showing.

penguin - ex politician who got caught dealing illegal arms using a private shipping port in the antarctic. It was called "project penguin"

wonder woman - please please please make her a lesbian. keep most everything else the same. keep her hair in a long braid. Up play the goddess centric
part of her culture. I think all themiscyra should have major problems with patriarchal culture and religions. As a matter of fact Diana should be so outspoken against 
christianity that the pope calls her the antichrist.

Steve Trevor - change him to a her. It just makes more sense that an island of amazons would be more likley to trust and help
a female fighter pilot, than a chauvenistic male.

hawkman/hawkgirl - imagine that in ancient egypt a culture name the thanagarians decide to colonize our little planet. They bring all
their tech etc and create what we see now as the golden age of egypt...Refer to stargate as a good reference. From that point, follow the smallville 
portrayal. isis and osiris legend, doomed to see eachother die life after life.

Atlanteans - the rival race of the thanagarians, the "Rhan" also decide to colonize this world. They settle on an artificial island in the atlantic.
eventually a large battle ensues, Atlantis sinks, and the thanagarians leave the planet.

after the eons go by, atlantis has forgotten its origins. Their time underwater has caused them to genetically alter themselves to their environment over time.
. In addition to all of this, they have lost all hair pigmentation from lack of sunlight over generations. So aquaman has white hair, and looks not 
completely human...

Hawkman and hawkgirl know nothing but their fragmented memories from previous lives.


meanwhile across the galaxy 4000 yrs ago Jor el of krypton is planning to send his only son to negotiate peace between these 2 races.
A stasis pod is outfitted with an education system to teach kal el all he must know.

while the pod is being launched General Zod initiates his final attack on krypton and the planet is destroyed. Shrapnel from the explosion 
damages kal els pod, leaving him locked in a static stasis and off course.

He is found in the late 20th century by the kent family while young Jonathan kent is drilling the well for their farm. Not knowing the origins of the
pod, and partially due to its biological technology they believe clark to be of mystical origins. they can offer him nothing from his past
as they raise him and help him control his powers.

Meanwhile the destruction of krypton and betrayal of Zod has not gone unnoticed. A coalition of planets residing in a yellow sun solar system commission a failsafe weapon
against the mad warlord. A doomsday weapon equipped to handle a super charged kryptonian is bred, programmed, and sent to an unsofisticated world full or resources to only be awakened to destroy
 what is believed to be the last kryptonians... Zod and his followers.


in the first century AD another alien arrives on earth. He is the former advisor and old friend of the late jorel of krypton. A seemingly immortal
shapeshifter originally from the planet mars. When the martian had returned home from endevors elsewhere he found Zod of Krypton and his companions ruling over a decimated mars.
Eventually he tricked them into a portal found in the milky ways asteroid belt. He traps them in the "phantom Zone". During this final battle of the last survivor of mars he learns of kryptons fate.
He has come to earth to look for the last remaining memory bank of kryptons knowledge. The life pod of the son of jor el.

The martian shifts himself into positions throughout history while he scours the globe. He brings new philosophies of peace to every portion of 
the globe he visits.


after centuries of searching, the martian locates another escape pod... From the lost kryptonian colony of Kandor. In it he finds an infant
girl suspended in stasis. Though her education circuit is functional, The martian canot bring her out of stasis. Out of desperation to save the race he uses
her DNA profile to clone her. The martian raises the cloned girl as his own under the name Jon Jonzz. (His alias immediatly preceeding this was "lucious fox") At twelve years old they discover
that the young girl is able to acess the kryptonian commands and unlock the infant from stasis.

With this new information Martian is able to track the passage of the original shuttle containing Kal El. It takes them several years to find him.

When Clark Kent is 19 yrs old, He is approached by the martian, a 23 yr old kara el and her "little sister", an 11 yr old girl. Training begins
as they take Clark to the arctic to begin his teaching. The martian entrusts the kents with his youngest girl during this time and until she is ready.

thus you have superman, powergirl, and supergirl working under the guidance of Martian Manhunter.

They set out to locate the descendants of Rhan And thanagar... Aquaman, hawkman, and hawkgirl.



Batman should be about 10 yrs older than clark.
Power girl should be a lesbian and eventually pair up with Wonder Woman.
Supergirl should be straight.
...

all the while the sleeping doomsday lies buried somewhere in the earth, and with zod no where around...any kryptonian is a target.

and thats all I have right now off the top of my head.
