>>101504440Jasper was a huge threat in her first appearance, she OHKO'D Garnet and captured Steven, Amethyst, and Pearl
She put up a pretty evenly matched fight against Garnet in the episode afterwards
Alexandrite x Malachite was also evey matched
She poofed some giant corrupted monsters with her bare hands
She destroyed Amethyst
And she did job against Stevonnie and Smoky Quartz, but that was after she got her fusion complex from being beaten by Garnet and trapped in Malachite, so it at least makes sense
She has accomplished more than any other antagonist has
Emerald's single appearance was of her screeching like an autist and getting BTFO by a townie character with no prior combat experience
