3. Ocean Master

Water Loki!!

Aquaman has never had a super great rogues gallery. I should know; I've written extensively about them. But Ocean Master is one of his most notable villains.

Orm was Arthur's half-brother. That has always remained true. What changed repeatedly was how that relation came to be.

At his inception, he was a human who was jealous of Arthur and decided to raid Atlantean cities. Later on, everyone decided that it made more sense for him to be an Atlantean who was jealous because this land lubber lost son was the new destined king. Which is how he totally became Water Loki.

It's shocking to me that no one ever made this comparison obvious in text. Ocean Master is a whiny jerk who just wants to be king. I think the reason he doesn't get more love is just that he just looks worse and has a dumber name.

He's kind of a dweeb.
