Nope. These are Superboy versions that only exist in this storyline, not in the original story. And we don't have pages for them yet, or put them on the disambig, because the storyline is not fully indexed. Karkan is a Tarzan-expy... but Tarzan isn't an Elseworld. Black Zero is the Superboy of a previously unvisited alternate universe.

Make sure to give your answers two at a time.
