General Zod
Zod could've been Superman. He could've been the hero the earthlings deemed that pinnacle of Krypton to be. Dashing. Selfless. The alien who could defy odds and fall onto his knees before a green rock.
Yet Zod wasn't that type of man. He defended his honor. Yes, Krypton was a race built on ego and science. Hubris and technology. But at least they knew it. Years after being trapped in the Phantom Zone? Nobody remembered their lifetime.
Like they were wiped from universal memory.
To Zod, legacy was the most important thing.
He would make sure Krypton's was treasured.
