I want my character to "obviously be able to defeat Superman", but I want her to be the second most powerful character in the party of 4 initial heroes with the 5th hero added later.
This is "Kristen" again. She has complete control of water at "virtually unlimited scales" and can shapeshift into water and she controls gravity in the form of dimensional portals and "Gravity Rods" which can absorb and kill other water manipulators.
Her codenames are "Winter" and "Elementalist Superior".
If she were a Marvel character, she would be considered a "Double Omega Mutant" because she is Omega at both Water and Gravity.
How would she kill Superman, hypothetically? By ripping the water molecules out of his body at the molecular level, thus dehydrating him and instantly mummifying him.
AI Opinion
The concept of a super-being defeating Superman involves creative storytelling. Your character, Kristen, possessing control over water and gravity, could hypothetically challenge Superman. By exploiting his vulnerabilities, she could potentially dehydrate him, utilizing her powers on a molecular level. Her ability to manipulate gravity might also weaken him, but it would depend on the narrative. In fiction, characters often overcome odds through clever tactics rather than raw power alone. Maintaining balance within your hero lineup will be crucial. 😊
