[TOMT][COMIC] Help me find a comic? I don't know if it was even real

Someone on r/comicbooks recommended that I posted here as well!

It's a vague memory from when I was a child and I only remember one part, so I'm sorry if there's not enough details.

What I remember is some panels where the main character (a superhero) has been captured and hung upside down with rope over what I think is an ice sheet or just snow in the arctic or Antarctica. He then has to eat an entire whale that has been hanging beside him dead. He does, and is seen with a big stomach after. It's probably a comic from 1970s-1990s from what I remember of the style.
