Because of sexual dimorphism, women in general are about 15% smaller than men on average. This in turn results in shorter reach and less mass to throw around as per the square-cube law. As a result, when women are taught to fight in martial arts or self-defense they are taught to fight in ways that either use the opponent's size against them or minimize the weight difference. Aikido or judo tend to be popular for this reason, as well as techniques such as aiming for soft targets or groin attacks.
I have a character who is female and is relatively tall for a woman (5'10"-6'0"). She is a shapeshifter and can shift into a large humanoid monster that is larger than most of her opponents, but she is also capable of performing minor feats of super strength in human form due to super-charging her body with short bursts of energy due to the same ability that can let her throw around adult humans. This character is self-taught through experience and is used to being the one of the physically strongest people in the room, she never learned what most people would consider typical self-defense. What I'm wondering is how this kind of life experience with powers would affect her fighting style? Given that she's not used to fighting at a weight disadvantage would this cause her to react or approach fights differently? Would she be less likely to use throws or holds because of this? Would there still be problems in combat with weight and reach because she is still a ~6 foot woman that is merely disproportionately strong for her size?
