>>104712160She's very, very strong. I mean Pearl... well...
And she's not even supposed to be strong. Diamonds, on the other hand, are the most powerful of all gems. God knows what they're capable of. Proportionally she should be appreciably stronger than the baseline Hulk.
Plus there's her lightning attack...
What can Aku do to her? Can he crack a diamond? Can he even get to ger gem?
