Lois will turn into a super-powered girl in the upcoming episode of "Smallville". When she and Clark visit the Fortress to get Jor-El's blessing for their marriage, Jor-El bestows a unique wedding gift on the couple. He gives Lois Clark's super powers so she can see what it's like to be him for a day.

Unfortunately, the Toyman has returned to Metropolis, so Lois must go up against the notorious villain instead of Clark. Meanwhile, Oliver searches for the Bow of Orion, which he believes will remove the Omega symbol from his skull, and runs into Kara, who is also on a mission to stop Darkseid. Chris Gautheir guest stars as the Toyman, and Laura Vandervoort returns as Kara aka Supergirl.

"Prophecy" will air Friday, May 6 on The CW. A week after, the show will air its two-hour finale.
