Post the source of the image, aldazo.

Edit: it's batman.

Batman? ummmm... I think you're right but it's just the costume, right? Also, do you see a "horn" with the mask? This is the source:

its a yeti

Pretty much this.
It's probably nothing special, but just some kind of a alien in Superman's Zoo. If NRS stayed true to the comics then maybe you could even see that creature in a show before. No biggie.

Btw, it is not Lex Luthor, its hands are just too gigantic .

The fight is taking place in the Batcave and the Batcave is full with all kinds of various Bat-costumes; one for every kind of adventures.
