One possibility is that the OC could become a powerful force for justice in their own way. They might use Black Adam's powers to protect the innocent in a more brutal and unforgiving manner than traditional heroes. For example, if there's a group of villains terrorizing a city, the OC could quickly and decisively stop them without hesitation, but perhaps with a bit more aggression than Superman or Batman would use.
The OC might struggle with the morality of having such power. Black Adam's powers are not just about physical strength but also carry a certain level of ruthlessness. The OC could find themselves on a slippery slope, debating whether to use their powers for good or being tempted by the darker aspects of having so much might. They might face opposition from other heroes who fear the OC is becoming too much like a dictator with their new - found powers.
Well, the OC could also have an impact on the power dynamics in the superhero world. With Black Adam's powers, they could be a significant threat to existing villains and even some heroes. This could lead to new alliances being formed. Maybe the OC teams up with anti - heroes who understand their more unorthodox approach to justice. Or they could be hunted down by a coalition of heroes who think they're too dangerous to be left unchecked.
