Injustice 2: 10 Incredibly Powerful DC Characters NetherRealm Left Out

5. Krona

Krona is basically DC Comics' personification of getting lost down a Reddit rabbit hole. He was a scientist compelled to feed his insatiable thirst for knowledge no matter what the cost - which has led to the destruction of entire universes and threats to existence.

On top of that he has enhanced physical attributes and huge psionic powers, and he's basically immortal, which helps when he keeps threatening to get himself killed seeking greater insight.

He might have been beaten a few times - and literally transformed into energy - but he's one of the most powerful, ancient powers in the DC Comics multiverse (which he actually helped create), and he'd be an excellent addition to Injustice's roster.
