Most underrated character?

I don't really feel like there's really any obvious 'underrated character', but if I had to pick one, I'd definitely say Pearl.

I mean, don't get me wrong, PLENTY of people like her just fine. But I feel like a lot of people make fun of her for being overemotional and salty towards Greg and even at moments, Steven

But I'd be pretty salty too if the girlfriend I'd had for about 5,000 years left me to flirt with a human, ended up having his child, and gave up that physical form for said child to exist.

Yeah, so, I feel like people need to cut her some slack. Not necessarily underrated, more under-appreciated, but I suppose they're similar.
