I guess we’re going with the comics here??? But let’s see…
1) Nat getting out of her constraints back in Liu’s BW, beating the shit out of her captor before Wolvie and Bucky even showed up.
2) In the Rucka/Grayson issues she has a moment where she finds out that the bad guys are using this formula that basically works people into a frenzy and has them kill other people and then the serum will kill who ever it’s used on. And Nat is really horrified by this and sheds a tear or too, but then immediately puts the gun back to the guys head and gets back to business. That moment has ALWAYS stood out to me.
3) Back to Liu’s run, I loved that moment when she was on a date with Bucky, but then found out one of the guys in the restaurant was abusive, so she, like, put her shoe in his mouth and tore through him and then went right back to her date.
