Lara-El is Superman's biological mother and the wife of Jor-El.
History[]

Lara and her husband Jor-El.
Lara's precise origins are unknown but it is possible that she worked as an assistant to scientist Jor-El on Krypton and they eventually married and had a son named Kal-El.
Soon Krypton began to crumble due to the infection of a virus spreading to the very core of the planet. With very little time, they salvaged what they could find to make a spaceship to send their baby boy to Earth which they considered a peaceful planet and also installed a globe that would give their son all the information he needed about his past as well as a shield resembling the House of El to let him know of his heritage.
They launched the ship into space, held each other's hands as they watched their son go and prepared themselves for the inevitable as their planet exploded into pieces.
Season 1[]
Some years later, Kal-El had grown up and was now known to the world as Clark Kent aka Superman.
He found the globe as he investigated the warehouse of Bureau 39 who had stolen the spaceship and took the globe with him. (Strange Visitor (From Another Planet))
Soon it began to play holograms of Jor-El telling his son about his past and heritage and images of Lara and himself saving their son.
Clark began to understand that Lara and Jor-El had saved his life and held them in high regard, but was still puzzled at why his biological parents couldn't save themselves. (Foundling)
Season 3[]
Lara later appeared with Jor-El as a dream in Superman's thoughts but was made to mess with Superman's mind by the villainous sorcerer Baron Sunday as a way of weakening the Man of Steel. But Superman once again understood of his origins and foiled Sunday's plans. (Never on Sunday)
