DP x DC Portal Collider

STAR labs has been abandoned for a long time, the particle collider was shut down after a series of system failures causing serious damage to the area.

Three years after its permanent closure, scans showed a spike in radiation coming off the previously defunct partial collider. It's assumed that something broke or reactivated and so the area is evacuated and the more durable members of the Justice League are called to come in and shut it down.

But in the center of the mess, they find a young adult with black hair and glowing green eyes frantically trying to keep the systems and monitors in check as inside a ring shaped section of the collider that had been jerry-rigged to the electrical wiring of the lab, a glowing green portal sputtered to life.
