Nothing special.. Just treat Pre Crisis Superman like a joke (And more impressively, Pre Crisis Batman )
He has the powers of the Legion of Super Heroes, and he can stack those powers (Meaning he has Mon El AND Ultra Boys AND Supergirls strength, speed, durability, ect... AND he can use Triplicate Girls powers to make three of him, all with the entire LOS powers..)

The ability to grow to giant size (Colossal Boy)
The ability to shrink (Shrinking Violet)
The ability to divide into 3 people (Triplicate Girl)
The ability to fire lightning bolts (Lightning Lad)
The ability to generate heat and light (Sun Boy)
The ability to make things super-lightweight (Light Lass)
The ability to make things super-heavy (Star Boy)
The ability to consume absolutely anything (Matter-Eater Lad)
The ability to turn invisible (Invisible Kid)
The ability to inflate into a large ball (Bouncing Boy)
The ability to stretch any part of his body (Elastic Lad)
The ability to shapeshift (Chameleon Boy)
Telepathy (Saturn Girl)
12th level intelligence (Brainiac 5)
Magnetic powers (Cosmic Boy)

Let them think what they want, let them define you in their narrow little minds while they suppress every last piece of them just to keep a friend that never liked them for themselves in the first place.
And all of those CPS powers are at Pre Crisis level. Sheesh, this sounds like someone who can be an even match for Galactus, level alone a single team of Avengers.
