Whatchtower duty

You are onboard the JLA watchtower having volunteered for monitor duty. This version of the watchtower was built on the surface of the moon overlooking planet earth. This one you built personally with technology gifted from various benefactors and funded by billionare Bruce Wayne. You made sure the security and defenses were top of line and strong enough to fend off Darkseid.

The current Justice league is comprised of seven core members with a reserve members roster to act as backup. You, Batman, Superman, Wonder Woman, Flash(Barry Allen), Green Lantern(Jessica Cruz), and Martian Manhunter are the core members. As of last week, you were elected to the chairmen position. Meaning you are the leader and representative of the league. Right now, The league is mostly inactive due to the low disaster rates and major villain attacks. So they are either dealing with problems that do not require league intervention or are taking personal time off.

All this peace and quiet means your time on monitor duty is mostly filled with cataloging information or dismantling some supervillian tech and studying it. However a signal comes from the teleporter meaning you have a visitor.
