So I really enjoy stories where Clockwork is either Kronos himself, or Kronos was just a fragment of Clockwork — like every version of Kronos is just a small piece of Clockwork's power, pushed into a body or created for a specific purpose. Either interpretation works and both are fun to explore.
Now, imagine this: Clockwork still has the ability to control the dead bodies of every version of himself — or rather, every Kronos across the multiverse. If he wants to, he can infuse a small piece of his power into a bone, an artifact, or a remnant from one of these iterations and temporarily reconstruct Kronos to serve a purpose. Once that purpose is fulfilled, the body is discarded or left inert.
In this , Clockwork has adopted Danny — either as a son or grandson (up to interpretation). As a ghostly parent, Clockwork is very protective of Danny.
One day, Danny is put in a danger that wasn't foreseen by time visions — a threat so severe that it could end him permanently. Driven by sheer ghost-parental instinct, Clockwork snaps.
He reclaims a form of Kronos (From its respective universe meaning the universe Danny is in either it be his own or a different one) and enters the physical plane. This act alone causes global panic, because as far as the world knows, Kronos has returned, and that never means anything good.
The Justice League and Justice League Dark are thrown into full alert, scrambling to figure out what prophecy they must have missed or what ancient evil has reawakened kronos .
While the heavy hitters try to confront "Kronos," the reality is this:
Clockwork is on a one-track mission — to rescue his son/grandson, and nothing, not even Diana (who is technically his granddaughter), is going to stop him.
(also the entity threatening Danny starts panicking the moment Kronos/Clockwork enters a certain radius — not even visible yet, but the pressure of his presence alone freezes them in fear. )
