Winter is coming – on Gotham. Season 2 of the FOX series returns post its midseason hiatus with a new episode featuring popular Batman villain, Mr Freeze.

Titled Wrath of the Villains: Mr. Freeze, episode 12 marks the arrival of Mr Freeze aka Victor Fries, played by House of Cards actor Nathan Darrow and another DC villain, Hugo Strange, essayed by Mr Robot and Jurassic World star, BD Wong. Looks like things are about to go from bad to worse for Jim Gordon.

A promo video for the upcoming episode shows a number of Mr Freeze's victims including police officers, getting frozen right where they are standing. "He's desperate and extremely dangerous," Jim can be heard saying, probably while addressing a group of operatives. Scenes go on to reveal just how deadly and menacing the 'cold-hearted villain' is as he points his cold gun to a police officer. "They think guns can stop me? They have no idea," says Mr Freeze.

Meanwhile, actor Robin Lord Taylor, who plays Oswald Cobblepot aka The Penguin, spoke to about his character moving more towards the dark side in the second half of the season. The character went through a bit of trauma in the earlier episodes when his mother was killed and his name got tied to the murder of Theo Galavan. (via Ecumenical News)

"He's untethered now, he can be the monster that everybody has always viewed him as," said Taylor. "Now that he has that license, it's going to get a lot darker."
