Red Shield 16. Continued from Action Comics (1938) #883 and continues in Superman (1939) #694.
*Supergirl has finally brought Reactron back to New Krypton so he can be held accountable for murdering her father, Zor-El. While the debate about what to do with him rages among the people of New Krypton, the planet's ruler – and Supergirl's mother – remains unsure. Should Alura have Reactron executed? And will Supergirl allow it to happen if her mother decides to go that route? *Source: dccomics.com
