(Mystic Comics v1 002, 1940)
Scourge of the year 2300, the Black Hawk and his Mercurian space pirates loot the spaceways of radioactive plinium in a bid to take over the entire Solar System. He’s also a pretty bad father, a fact that comes back to bite him (fatally) when his daughter Alyse teams up with the Space Rangers to take him down.
Kids, amirite?
