#pre flashpoint

Like main characters and big events etc

Well….

Earth 4080, basically the idea for it consists of largely combining parts of Pre Flashpoint Canon, Teen Titans Animated elements, DCAU/Timmverse influences, and of course drawing from elseworlds including Kingdom Come and Nightwing The New Order alongside some buts from the Post Flashpoint Rebirth era and even tiny dashes of both The Absolute Universe and both cinematic universes (Snyder and Gunnverses) if need be

Maybe as a good way to start things off;

Wonder Woman is the actual first ‘proper’ superhero in this timeline, first emerging during the waning years of the First World War, this adventure taking direct inspiration from the 2017 movie. Main differences here are that Steve Trevor not only survives the war but thanks to being the first non Amazon exposed to the Purple Rays, his aging was majorly slowed down, only aging by a single year for every decade that passes. As for Diana herself post WW1, she continually operates across the globe helping save lives and intervening in wars in secret, eventually gathering a small band of fellow heroes emerging in the interwar period with their own distinct powers and gimmicks (Jay Garrick being connected to the Speed Force, Alan Scott finding a long lost vessel of the ancient entity of Willpower Ion within a lantern, Carter Hall tapping into his past incarnation’s links with Nth Metal, etc) forming the secret and well hidden Justice Society just in time for the Second World War

So far so good?

And then promptly knocking on the nearest window and offering a small wad of cash and the promise of replenishing what he takes, haggling for a moment or two (okay, fine he'll throw large spectrum antibiotics on top of the replenishment as well) and being handed a medical kit that has more stuff than Tim can carry in his utility belt and then getting to work on stabilizing the person until the ambulance can get there.

On the Pre-Flashpoint Earth, Harper Row notices Red Robin going on a downward spiral (RR #26), and decides she'll become Bluebird to keep him in check as his partner (The irony of this is not lost on Tim (or anyone else for that matter), and he hates it).
