Well into their 2015 comeback, Big Bang is now making appearances on several popular variety shows. The boys recently wrapped up a special on "Happy Together," where plenty was revealed about the group's past.

But there's nothing like Big Bang on SBS's "Running Man."

According to Koreaboo, Big Bang recently completed filming a new episode of "Running Man" on May 25. A photo of the K-pop group in gladiator costumes was recently uploaded to the official SBS "Running Man" twitter account, available to view below. Additionally, it was also revealed that the filming took place at the racing circuit in Gangwondo, leading some to speculate that the episode will have something to do with racing.

So far, most fan reactions to the announcement about Big Bang's "Running Man" appearance are related to G-dragon and Taeyang's new hair colors.

"Red hair GD! Pink hair Taeyang," exclaimed Kazieng Chang on Facebook.

International Big Bang fans are however lamenting how long they will have to wait for English subtitled episodes.

"I am really looking forward to this episode. I hope they put up English subs fast because I'm still waiting for 'Happy Together' with English subs," lamented Megan Leuma-Masaniai.

Big Bang's "Running Man" photo also included cast member Kim Jong Kook dressed as a gladiator, leading some to wonder if he'll be joining their group as a team for a challenge in the show. Unfortunately, there's no telling when fans might find out what the gladiator outfits are for, as the episode air date has yet to be confirmed.

It may not be certain when VIPs will get to see Big Bang on "Running Man," but the group is scheduled to release another single from their "Made" album on June 1. With yet another release coming, VIPs are sure to have plenty of Big Bang action over the next few months.
