What do you think of the various Superboy incarnations that have appeared over the decades?
I have to admit, I do not like Clark wearing a costume and fighting crime in Smallville as a kidr, because it really strains credibility that people would not put two and two together and figure out Clark is Superman, if Superboy was active in Smallville before Clark came to Metropolis. I think Clark using his powers to foil some crimes in Smallville in a more subtle way works, but I think Clark becoming Superman should be a bit of journey, rather then him donning a costume as a young lad.
I kinda like the young clone Superboy, Kon-El.
Superboy Prime is a bad character, it seems the writers are trying to troll the fans with this character and he is annoying because of that.
I think young Jonathan Kent has some potential.
