Martian Messenger

The 1913 film Message from Mars is considered to be the first British science fiction feature film. Ramiel is a being from Mars sent to reform the most selfish man on Earth.

A descriptive intertitle states:
RAMIEL, HAVING BROKEN ONE OF THE LAWS OF THE KINGDOM, IS COMMANDED BY THE "GOD OF MARS" TO PROCEED TO EARTH AND REDEEM THE MOST SELFISH OF MORTALS.

Though not deeply described in the film, it appears that Martians in this tale act as a sort of angelic beings. They have no wings, yet display powers and 'moral' interests similar to those often given to angels in stories and writings.

Brief Plot Synopsis (full synopsis here)

Motivated to restore his standing in the 'court' of the God of Mars, and retrieve his Ankh jewel worn by all those in favor of the court, Ramiel (E. Holman Clark) is subsequently sent to Earth to redeem from his selfishness the character of Horace Parker (Charles Hawtrey).

Through several trials meant to encourage unselfish acts placed to Horace, to which Horace responds grudgingly at first, Ramiel eventually sets Horace right.

POWERS AND ABILITIES

Ramiel is invisible to all but Horace, though it is presumed he can become visible to anyone. He sets up situations whereby Horace might be tested, and also he may change the appearance of other people, for example he makes Horace appear as a beggar to others, suggesting reality manipulation. He can teleport instantly. On Mars, he can show Horace's progress through a crystal ball type of apparatus.
