Flint (Stormwatch) vs Power Princess
Flint
Flint's skin is rock-hard, and she seems to be pretty much invulnerable. Bullets affect her about as much as a stiff rain, and even a rocket can at most knock her back and damage her costume. Dropping her from a great height will result in a crater and an unfazed Flint. She does seem more vulnerable to energy weapons.
Although she doesn't display extreme super-strength, her blows have impressive power - presumably a combination of her strength, speed and rock-hard hands. She can behead a normal man in a single punch, and has been known to kill bulletproof superhumans with a good rush-by punch to the jaw.
In recent years, Flint has displayed super-speed - she can do easy things faster than humanly possible (such as changing clothes), and is superhumanly good at catching projectiles in mid-flight. She is also very proficient at grabbing large objects and throwing them with great fluidity, power and accuracy.
She is able to create a brutal, vectorized shockwave by slamming her hands together - the resultant blast of pressurized air is enough to break the back of a normal man.
