I've looked into the DC Wiki and discovered that the "Man of Steel" has a bigger family in the comics than the TV series, specifically the Phaelosian twins Osul-Ra and Otho-Ra. They and their species are the evolutionary offset of the extinct Kryptonian race and live on New Phaelosia, but they were kidnapped by the Warzoon tyrant Mongul and forced to fight for entertainment on Warworld.
It even said that their power comes from the Old God Olgrun and they can use Genesis as an alternative power source than yellow sunlight to fuel their powers. So, here's an idea, why not put the Super Twins in the new Superman series here!! I can see and imagine it quite clearly, it would rock the children's world of entertainment and action.
They can even some of the powers depicted in the DC Wiki:
Solar Radiation Absorption
Superhuman Strength
Superhuman Speed
Invulnerability
Flight
Heat Vision
Super-Hearing
Super-Breath
X-Ray Vision
Genesis Energy Absorption
Energy Manipulation
Optic Blast
Energy Construct Creation
Force Field
