Bizarro tried to kill Clark, but was weakened by the yellow sun and knocked out by Clark. He forced Lex to show him his stocks of green kryptonite to strengthen himself again. After knocking Lex unconscious, Bizarro fought with Clark again. Clark punched him upward into the sky from where he was taken away by the Martian Manhunter.
Goof: When Clark and Manhunter are in his Barn talking about how to stop Bizarro and figuring out the yellow sun can heal Clark, there is a beep of a watch or someting similar in the background, but neither Clark nor the Manhunter react to it, which means it happened off screen and unintentionally.
Trivia: In the comics, Bizarro is an enemy of Superman, often shown to be a mirror-image of the Man of Steel.
