Want to point out that ABHI left out some context to the Black hole showing. Before the Black hole appeared (the Black Hole Superman created just by thinking), this happened.

Lois gave Superman Brainiac powers. Superman then creates a Black hole and suck both him, Brainiac and the ship into it. Superman was amped tremendously during that showing. What Superdoom did on during all of this is bust through the ship, fought some aliens, and disconnected Brainiac. Diana defeated Mongul and had War World attack Brainiac ship (yes, she defeated Mongul AND a Kryptonian by herself. A being that took on both Superman and an amped Batman by himself. Diana is operating at some insane levels) and Lois took control of Brainiac and was about to kill him.
