Robin III - Suicide Squad: Kill the Justice League

The alter-ego of Tim Drake, Robin III, is still an active member of the Bat-Family following the Nightfall Protocol.  

He was ambushed in the Metropolis Batcave while trying to access the Babel Protocols and seemingly killed by "Batman". 

Though since "Batman" had expressed a desire to capture and integrate Oracle, it is also highly possible that they kept him alive, imprisoning him aboard Brainiac's command ship with the rest of the defeated and cloned heroes.
