Storyline

When Halk Kar crashes on Earth, the note he carries in Jor-El's handwriting makes Superman suspect that Halk Kar is his older brother. But when Halk Kar joins Superman in his pursuit of "Wrecker" Ross, Halk Kar receives an electric shock and remembers that he is actually a space traveller from Thoron who met Jor-El on Krypton just before it exploded.
