AceShowbiz - Lex Luthor is making his way to "Supergirl". The arrival of the major character in the fourth season of The CW's series has been awaited, and much to everyone's liking, the network has unearthed the first look at the character, which will be played by Jon Cryer ("Two and a Half Men").

In the photo, the brother of Lena Luthor (Katie McGrath) and the son of Lilian Luthor (Brenda Strong), is featured giving a deadly look through the door of a maximum security jail cell. Sporting beard, he has his arms crossed while his head is bald as ever.

"Steel can't hold him back. Make sure you're caught up before his arrival," the official Twitter account of the series teases.

While some other fans are questioning the casting choice, a fan jumps to Jon's defense. "People don't judge yet @MrJonCryer solely based on his look. Jon is a great versatile actor. As an actor myself, I appreciate and have seen Jon's work from Pretty in Pink, to Superman IV, Two and a Half Men...," the fan gushes. "I'm confident he's going to put his own stamp and take on the role."

Luthor will be featured in upcoming episode 15 of season 4. While he won't appear until then, it is wildly believed that Lex has been manipulating events on "Supergirl" since season 1. The popular theory also suggested that the villain intentionally got himself arrested by Superman before the series began, so he could continue to work in the shadows without Kara and her cousin knowing about it.

Prior to meeting Lex, fans of "Supergirl" was treated to Dreamer a.k.a. Nia Nal (Nicole Maines), the very first transgender superhero in TV's history. Also known as Dream Girl, Dreamer is originated from a planet called Naltor, a world where almost everyone has precognitive abilities.

"Supergirl" season 4 airs on Sundays at 8 P.M. on The CW.
