Solar Radiation Absorption In a nutshell, his body is capable of storing and using solar radiation depending on the sun. Yellow suns give him the enhanced abilities he and his father both have on Earth.
Invulnerability A tough cookie difficult to physically harm. He's capable of withstanding a great deal of physical traumas, often bouncing back from them with little to no injuries. Not always the case, such as when he's vulnerable or power instability is going on, but. He's more or less invulnerable when not being power dampened.
Superhuman Strength, Speed, Stamina, Senses Superhuman and enhanced abilities thanks to his being half-Kryptonian. He's strong, he's fast, he's difficult to keep down, and capable of hearing, seeing, and even smelling from great distances.
Flight No pixie dust and happy thoughts needed here, Jon has the ability to (finally) fly even if it's still relatively new to it.
Heat Vision and Super Breath Laser eyes and freezing things with a huff and puff and a blow of air from him. With the breath also comes the ability to shatter things with his voice and maybe get to the whole hurricane levels of winds, but. You know. He's still learning and all.
Also, like his father, Jon has an indomitable will but that doesn't mean he isn't capable of being mind manipulated with magic or other means. The Kryptonite thing is also a weakness to him as well as needing a yellow sun to replenish his body/powers.
🌞 powers.
