TTK is a must Imo, there are way to many adaption of kon now that don't have it, such a disservice to him.
I would make his TTK a mutation of his kryptonian powers, where he has the same power source, but they work separately and differently.
He should have to work harder to use his powers, but be able to do more with his than they can with their powers.
Yes to Invisibility, I forgot to put thst on my list.
The DCAMU suit is a good one, I would make the S on his chest black and red and give him fingerless gloves, PLUS age him up and give him the body of the YJ shows superboy
