Supergirl, Season 5

Brainy:
Thank god for selfie culture. Because of this generation's constant need to live stream everything, we've got a clear image of your attacker. And I knew I had seen that face before. Do you recall Antioch, 526 AD?

Lena:
It was an earthquake. It was the eighth-largest natural disaster in modern history.

Brainy:
Precisely. It's good to have you back, Lena. A myth was born that this man was the cause. Now, of course, scientists insisted that the natural disasters were natural, but in an ironic twist of history, they were wrong, and the fearmongers were right. Several reliable sources place this man at the scene of the crime throughout history. Pompeii, the Yellow River flood of 1887, the Bhola cyclone, even as far back as Noah's flood, this Earth-Bender has been spotted.

Alex:
Excuse me, did you say "Earth-Bender"?

Brainy:
How else would you describe him? He... he literally manipulates the earth.

Supergirl:
But wait. Pompeii, Noah's flood? I mean, what is he, thousands of years old?

Brainy:
Correct. Which means he's an alien with powers of longevity this civilization has never conceived of.

Alex:
No wonder people thought he was a myth.

Lena:
With all this destruction, his existence is still shrouded in mystery. He's managed to convince the world he doesn't exist.
