Synopsis for Supergirl: "No Mercy for Supergirl!"
When Supergirl tries to recover the notes left by an experimenter in diseases for the World Health Organization, she is captured by a tractor-beam wielded by an alien calling himself
the Avenger. The Avenger is from the planet Sarkon, whose laws absolutely forbid taking any life whatever. For super-beings who flaunt this law, the penalty is imprisonment in the 5th Continuum. Since Supergirl has been observed cutting a flower and killing a butterfly for a collection, he sentences her to die. However, Supergirl tricks the Avenger into killing some
disease germs. Convicted by his own law, the Avenger commits suicide.
