Lar Gand

Lar Gand, known mainly as Mon-El (and alternatively as Valor and M'Onel), is a superhero appearing in American comic books published by DC Comics, commonly in association with the Legion of Super-Heroes, Superboy, and Superman. Lar Gand is a Daxamite, an alien with similar abilities to that of a Kryptonian, but originating from another planet. The character has been reinterpreted over the years, but in all versions serves as a hero with abilities similar to those of Superman, sometimes serving as a substitute for him. It's usually portrayed that Mon-El meets Superman in his adolescence, when he was still Superboy in Smallville, the two become friends and Lar Gand becomes a kind of older brother figure for Clark. Clark names Lar Gand with the Kryptonian name "Mon-El", giving him a name similar to that of a Kryptonian as a sign of the friendship and brotherhood that unites them both. Mon-El later succumbs to lead poisoning and is placed in the Phantom Zone to prevent the spread of the poison, from where he is released by the Legion of Super-Heroes in the future when a cure is found for his poisoning. Mon-El appears in the second season of Supergirl, portrayed by Chris Wood. Additionally, Superman X, a character loosely based on Mon-El, appears in the animated series Legion of Super Heroes, voiced by Yuri Lowenthal.
