Both of these two beings are top of the line fighters. They have vast super strength, Vast Super Speed, and an array of other powers. Superman can shapeshift, and use his Heat Vision and Freeze Breath.

Supergirl also has her Heat Vision and Freeze Breath. Superman has been crime fighting since before the fifties and knows the ropes. While Supergirl hasn’t been fighting as long she still has lots of battle experience and isn’t to be taken lightly.

She loses this match since she’s just not as strong as Superman in the end, but she will be getting wins soon. That’s one thing we can count on. This isn’t an easy match for Superman. It’ll come down to the wire. Superman wins.
Who would win depends on which version of Supergirl you are talking about.The original 1960s girl of steal was more skill full than Superman was. She had to train and do her super deeds in secret for years and trained to fight without using her super power. hey came to blows a few times and she came out on top every time.
Well, both are composite and at their strongest forms. So, it would be tough for Supergirl to beat him thanks to his 1 million form and others
He is men and he wins
Never underestimate the solar power energy! Superman can’t be stopped, but it doesn’t have to do with the gender dynamics. It’s just that he’s too awesome to lose.
