Not only these powers, but he has the power to augment others, much like Galactus, as he has shown with Psycho Pirate (but not to the same extent).
Now for all intelligent comic readers, the conversation should end there. However...
Parallax-Living embodiment of fear, can alter reality however he sees fit.
Prime-All the powers of a Kryptonian (Superman of Earth 2 equivalent) but not limited by exposure to yellow sun radiation thanks to his indestructable Monitor armour. Claims he has no weakness to magic, and not affected by this universe's Kryptonite.
Cyborg Superman-Complete control over machinery, able to build and animate any type of machine, All of Superman's powers, Indestructable body, with the ability to transfer his consciousness to another body if the unthinkable happens, additionally Henshaw now wields ten Qwardian power rings.
Control over full Manhunter army, the second strongest weapons in the universe, apparently.
