Ah, now this is where it gets really interesting. Steven Universe is half-Gem, half-human, and he definitely has ears. You can see them poking out under his curly hair in most episodes.
But here’s the kicker: Steven can still use Gem powers. His shield, his healing spit, even his dream-walking abilities—none of that requires him to lose his ears. So maybe hearing is just a biological bonus for him.
Or, maybe his Gem half gives him a "sixth sense" for sound, and the ears are just for show. Either way, it proves that a character can be both relatable (human-like) and magical. It’s a cute compromise that makes Steven feel like a bridge between two worlds.
Why This Silly Question Actually Matters
You might be thinking, "Okay, but why do I care about Gem ear anatomy?" Because it’s a perfect example of worldbuilding through subtraction. The creators didn’t just forget to draw ears; they deliberately omitted them to remind us that Gems are something else.
It’s like how they don’t eat food (except for that one time Amethyst ate a whole pizza). Every weird detail—like no ears, no internal organs, no sleep—is a clue that these characters don’t play by human rules. It makes their occasional moments of love and vulnerability hit way harder.
Punk Rocks : r/stevenuniverse
So, when Garnet says she "sees" the future, maybe she also "hears" it in a way we can’t understand. You don’t need ears to listen to the universe. You just need to vibe with it.
