Action doodles

I've been studying some action/fight movements in the hopes of getting better at drawing them Except for peridot there, that was just for fun ^-^ Aah I just realized I have a bunch of things I should be getting to drawing though, this shall remain an unfinished doodle x-x
I think Sapphire's weapon might be brass knuckles, I was thinking maybe a glove like Ruby's at first, but it'd make no sense to summon another glove over her gloves xD
