First appearance: Alpha Flight #1 Vol. 1. She was a member of the Canadian super-team AF, plus a guest member of the Avengers, whom Namor was in love with, and when they married (briefly), she became queen of his newly founded kingdom of Deluvia.
Current status: dead
Was subjected to the following acts of discrimination: in Avengers #272, we discovered that she’d suffered from a disease that damaged her face, but which was fortunately cured (following this, she and Namor married). But the troubles didn’t stop there. In Avengers #291, she went insane as a side effect of pregnancy with sea animals(?) and transformed into a colossal sea monster called Leviathan, and two issues later in Avengers #293, her husband, prince Namor of Atlantis was forced to kill her with Black Knight’s ebony blade.
What’s wrong with how this was done? Why did the prince of Atlantis have to suffer two losses of loves? First Lady Dorma and then Marrina as well? I feel that’s going way too far.
I wonder if it ever had anything to do with Roger Stern’s being taken off the series at around that time. Maybe because he didn’t want to kill off Marrina, but TPTB did, and so Stern was ejected and replaced with Ralph Macchio, who wrote the book for about a year. But so far, I have no clear way of telling.
