A rocketship blasts away from an exploding planet just in time. Inside the ship, the last survivor of an entire civilization sleeps. His destination: 20th-century Earth. Only the Kryptonian ship veers off-course, enduring a thousand-year journey into the 30th century, where it ends up being discovered by billionaire industrialist R.J. Brande.The story of the Last Son of Krypton takes a different, yet somehow familiar twist in this two-issue Elseworlds mini-series. Brande's now adopted son, "Kal," grows up an impetuous teenager with powers and abilities far beyond those of mortal men. Alone and without purpose, Kal is regarded by many as a childish boy who dreams about the super-heroes who protected Earth a millennium ago. But certain events prompt young Kal to turn those dreams into reality, as he decides to find other unique teens like himself and form a Legion of Super-Heroes. Unfortunately, their first mission may turn into a nightmare for the young group of heroes, as unseen forces enter the equation and look to strengthen their grip on a universe they already control.
