The Superman Family

The Superman Family is an American comic book series published by DC Comics from 1974 to 1982. It was created through the merger of several earlier titles set in the Superman universe, including Superman's Girlfriend Lois Lane, Superman's Pal Jimmy Olson, and Supergirl. Other characters, including Krypto, Superboy, and Clark Kent (in The Private Life of Clark Kent) also starred in their own short stories.

Supergirl: Cleopatra, Queen of America (Volume 1, Issue 171)
Lilibet Winsor comes into possession of an ancient Egyptian scepter originally owned by Cleopatra. The scepter has the power to control minds. Lilibet heads to Washington DC and uses the scepter to convince the US government to proclaim her the new ruler of America (as "Cleopatra of the Potomac"). Supergirl and Batgirl are immune to her powers, so "Cleopatra" sends the hypnotized members of the Justice League to stop them.

Lois Lane: Piece of Mind (Volume 1, Issue 184)
An annoyed Lois is sent on a 'puff piece' assignment to write a story about Father DeMurr, a New Age guru who runs a meditation group. She spots DeMurr meeting with a hit man from the criminal SKULL gang, but ends up getting kidnapped by SKULL and subjected to DeMurr's "meditation" techniques- a brainwashing process that he uses to program her to kill Clark Kent. Clark speed-shifts between his Superman and Clark personas to confuse Lois, breaking her trance (luckily, a side-effect of the brainwashing is that the victims forget everything).
