Why is Caelum so weak? He’s got heat vision and super hearing, yet the super strenght, speed, and endurance is not here. Which is weird since Clark Kent was able to carry tractors and trucks with one hand as a baby.
Caelum literally lifted a barrel full of Ale by himself.... which according to Google is 650 pounds ler barrel. He did that at age 7, how much stronger do you want him to be?
it's just that he hasn't done anything overt to expose that strength.
What else do you want?
