I'm talking about characters planet/star-system/galaxy-sized. Characters like Unicron, the 2001: A Space Odyssey baby, and even meta-characters, like Tenga Toppa Gurren Lagann (a ship powered by all of humanity's fighting spirit) would count in this list. The Borg Collective is also something I would consider, as each individual unit considers themselves the same as the whole. I would only count characters who can change size at will if they ever were depicted as growing to such a size, or if there is a related, official story/myth of them ever doing this.

I've done many searches, and can't find a list with characters on this scale. The best list I found was one that featured a 30-foot human somewhere near the middle.

  • Related, and exactly why this question is a poor fit for this site: What is the largest (engineered) physical object dreamed of in science fiction? – phantom42 Sep 16 '14 at 17:19
  • Aw, c'mon, this is a great question to spark some fascinating discussions. So what if it's broad, let's see what people say. – PopularIsn'tRight Sep 16 '14 at 20:17

  • "this is a great question to spark some fascinating discussions." The main site isn't for discussions. We have chat rooms for those. – phantom42 Sep 17 '14 at 14:09
  • If you re-word the question to tighten it up, please include whether or not to include comic books, movies, etc. Characters such as Galactus spring to mind but aren't strictly science-fiction per se. – Omegacron Sep 17 '14 at 17:34

In the Futurama film "The Beast with a Billion Backs", the crew encounter a creature the size of an entire universe (named Yivo).

Although his size is presented inconsistently, I doubt if you'll find a larger fictional character.

  • "God" depending on your view, encompasses everything and is everywhere at once. so in essence hes infinite. – Himarm Sep 16 '14 at 18:24

    @himarm - The site rules make it clear that God (or other deities worshipped in the real world) is not considered a fictional character. – Valorum Sep 16 '14 at 19:08
  • hadn't seem that, but thats a great policy. we are allowed to include fictional gods even if their based on another god? in example aslan or eru would be similar in that they are infinite. while both being based loosely off of "God" – Himarm Sep 16 '14 at 19:38
  • @Himarm - Yes, absolutely. A question about "the presence" (en.wikipedia.org/wiki/Presence_(DC_Comics)) would be on topic, despite it being the literal depiction of the (real world) Judeo/Christian deity. – Valorum Sep 16 '14 at 19:51

    Indeed... I was gonna answer with "Universe Man, Universe Man. Size of the entire universe man. Usually kind to smaller men. He's got a watch with a minute hand, a millennium hand and an eon hand, and when they meet it's Happy Land. Powerful man: Universe Man."—They Might Be Giants – Lexible Sep 17 '14 at 6:25
