Check out these great costumes The CW Network stars rocked last night for Halloween!

Is Jensen Ackles angling for a spot in the Crisis on Infinite Earths Crossover event? Because his Halloween costume certainly looks like it! 

The Supernatural star donned a custom Batman suit and even snapped some picturesque photos with the looming Gotham city in the background.

Looks like Cody Christian from All American got his costume inspiration from the latest Joker movie! 

Arrow star Stephen Amell and his wife went for a more comedic look as a hot dog and a can of beans or in other words, a perfect match!

Nicole Kang of Batwoman showed off two of her costumes including a spooky alien and the latest Batwoman villain, Magpie!

Feeling inspired? Only 364 days until the next Halloween!

Until then catch all the spooks and scares you can handle on Chicago's New Home for The CW, CW26.
