Heroines who are OP female generals, mech masters, super powered ability users, martial arts experts, military snipers, powerful Empress Dowagers, interstellar zookeepers and beast tamers, etc. 

(Formerly titled "FL Who Can Beat Everyone Up", but I wanted to clarify it's the female protagonist/MC, not the FL/side character, that I was referring to.)

(Just to be clear, the interstellar OP zookeeper doesn't beat people up, she can just control/soothe/dominate any war beast...)
