I've honestly seen very very very... few anime characters with this degree and range and variety of expressivity... and on top of that, during highly frenetic and dynamic fight scenes! Seriously, she's a charm to see during the whole show, but there are moments during the fights in which she express feelings by facial expression so fast one almost needs to pause the video to catch em (a bit like if they weren't even necessary, but the animator just wanted to do it... because damn yeah!)

Also I like how clearly and wickedly she friggin enjoys beating up aliens and terminator wannabes...
