Mon-El

Lar Gand, known mainly as Mon-El (and alternatively as Valor and M’Onel), is a fictional character appearing in American comic books published by DC Comics, commonly in association with the Legion of Super-Heroes, Superboy, and Superman. The character has been reinterpreted over the years, but in all versions, he serves as a hero with abilities similar to those of Superman, sometimes serving as a substitute for him.
The character made his live-action debut in season 2 of the Arrowverse TV series Supergirl, played by Chris Wood as a regular character for several seasons. A character loosely patterned on Mon-El was previously adapted for the Legion of Super Heroes animated series.
