However, before the team can celebrate, the Boom Tube used to return to Earth was not closed and Darkseid's son Kalibak arrives and attacks the team. During the fight, Kalibak beats the team nearly to death, when suddenly Damian knocks out Kalibak with a powerful uppercut; discovering that due to the Chaos Shard he has gained superhuman abilities. While Damian fights Kalibak, Batman remotely controls the Batwing and sends it crashing into Kalibak, sending him back through the Boom Tube and then closes the portal.
