Kon-El's best friend whom he worked with in Young Justice and later Teen Titans and who makes a handful of appearances in Kon's own books.

Another of Kon-El's closest friends in the superhero community.

Hillary Chang
The first friend Kon-El makes when he starts attending Ilupani High School in Honolulu.

- Snark-to-Snark Combat: With Kon and Tana who are both sharp enough to catch on and respond when she snarks at them, her best friend Robert on the other hand bemusedly catches on to what she's saying but knows he's too outclassed in the snark category by her to usually bother responding in kind.
