Namor at max sig reflects all the damage he would get, and at a very high sig but not max, he’d reflect most of the damage. Other good counters are Quake, Havok and Falcon
Non-contact medium/Hvy attacks don't trigger the Thorns damage. Havok's basically immune to Korg's passive damage, except for the kick on his SP2.
The Damage also don't act if the opponent's basic attacks deal energy damage, which includes a lot of champs these days - Doom and Magneto being top examples.
Havok also punishes people who shrug off his Plasma debuffs. So you can spam SP1 to eat away at Korg's health, although this can maintain his Rock Shield.

Namor also works.
I recommend Regen champs (like Voodoo, Wolvie, X-23, Diablo ect), they can work too
-no thorns damage
-prefight passive stuns
phase and then throw lights get rid of rock shield
throw sp2 bam and repeat
Stryfe
Mags
Or any energy base champ
Apoc for better fight control as he can't shrug his stun
