Mismatched

You're aqua regia and I'm precious gold.
I'm superman. Is that kryptonite u hold?
Your warm water and I'm sugar.
My love is loyal, your heart's a hooker.
You're Harley Quinn, when Alfred's my butler.
My character shines, yours has no color.
You're cold on the inside, as I come with fire.
I speak the truth, and you're just a liar.
You're Cronus sickle and I'm Zeus bolt.
My success shocks, yours doesn't bring a jolt.
You're a peasant and I'm a knight.
My love is agape, yours won't even fight.
You're my opposite, we are not the same.
I'll be remembered as they forget your name.
