Kal-El (Bizarro World)

"Why are you here, Kal-El? To save my world... And yours."

- Lara Lor-Van A.I. and Kal-El

Kal-El is a doppelgänger of Superman who was trapped in the Shuster Mines.

The Thing in the Mines
At some point, Bizarro got trapped in the Shuster Mines, and his attempts to escape caused earthquakes in Smallville. This drew the attention of AmerTek, who sent several employees into the mines to investigate, all of whom were killed by Bizarro.

Bizarro later escaped the mines and fought Superman and Steel, during which time he asked them to “leave him alone” backwards. He and Superman then began to experience painful visions, which caused Bizarro to fly away to the Fortress of Solitude. He then removed his armor to reveal his mirrored suit, before saying the word "home" backwards.

Bizarre
Some time later, Bizarro flew to the Kent Farm, where he briefly fought Superman and John Henry Irons before fleeing to Salar de Uyuni, Bolivia. Once there, he fought the Supermen of America, killing two members before Superman arrived. The pair then fought each other until John Henry Irons arrived and attempted to help using his hammer. However, this resulted in him being struck hard enough to be hospitalized before Bizarro fled.
