Damian was born from his mortal father and a goddess for a mother. Of course he was greater than the other boys and men.

The Fates had decided it was so.

That Damian Wayne was destined to die in war. The prince would not live to be king, or to ascend to Godhood: he was to die.

Damian chooses to train anyway. Even if his mother is hiding him away from the world. Hoping to prevent his death in some way.
