Demon Twin AU
Tim Drake comes across a LOA manuscript detailing the sacrifice of a Demon Heir that’s dated around the time Damian is born and brings it to the cave. There’s no other mention of what went down, but it looks like Damian was a twin and the twin was thrown into the Lazaras Pits- Tim kind of forgets about it but shows it to Damian cause he figures that the guy deserves to know, and leaves it out for Bruce to see (basically the same thing as telling him). It doesn’t really change much but there is an obscured name in the corner so they can presume that the kid’s name would have been something starting with D A N.
Well here’s the thing: Names carry power. Damian reaches out to John Constantine to ensure that the child is actually dead, because presumably John can do that. John wants to give the kid some closure, so he does what is supposed to be a super chill seance to an infant. He pricks Robin’s finger, chants a little and the air… turns violent.
Uh oh. Dan appears, unshackled from his prison in the Infinite Realms now that John has called upon them by someone with Familial blood. He cackles madly about the fact that it’ll be a good time to bring about the apocalypse again, promising to spare the bird for now, since he would have to get answers later.
The alarms are blaring, the whole JL is hands on deck to try and stop Dan as he attacks across the globe. They’re saving as many civilian lives as possible but its getting very HAIRY in less than 2 hrs. Robin is out in the chaos, trying to track him down with John and Zatanna trying to recapture him and banish him back to the realms.
Phantom touches down just as the three of them reach Dan- Danny has some choice words for his older alternate timeline self, including “This is why you have no friends.” and “Seriously, you didn’t even stop to say hi to my timeline’s Jazz this time.” and “Soup time for 1,000 years and then we can talk remediation.”
After a short but brutal fight, Danny floats over to Damian, John and Z. After making sure they’re all right he’s like “Maybe you can never do that again? Also tell me how and why you did that so I can banish that spell?” And Damian explains that it was meant to ensure that the infant twin he never knew had passed peacefully and clearly that was not the case. Danny blinks a few times, uh, a twin?
Damian goes through the shit, John explains that it was a familial summoning meant to be an advanced seance (hence the lack of safe guards to keep the entity in) and Z confirms that there was nothing special to it beyond that.
Danny then explains, that uh, “I guess my parents weren’t kidding when they told me I was adopted. Hi? I’m your brother. Uh, I go by Danny though. Dan was me in a different timeline and he’s normally under super strict lockdown.”
