Kusanagi with truth.
It's a myth that throws suck in MBAA, even compared to other fighting games.
However, normal 4/6E throws are AWFUL on defense, despite their speed. To get hit by a throw, your character's collision box must be touching theirs, so even if they do happen to mistime a meaty 2a, they have to be right in your face for your defensive throw to land. You shouldn't be mistiming your meaty anyway, but you can avoid getting hit by a defensive throw by positioning yourself just a few pixels away from their collision box, the throw will whiff, and they get BLOWN UP.
Command throws are a bit different, they grab your normal (fatter) hitbox instead of the collision box. So a fast command throw such as Kohaku's or Kouma's could grab you while your hitbox is still extended from your mistimed meaty attack. Their defensive use is still gimmicky shit, but far better than normal throws.
