It’s hard to tell if the latest batch of teaser images from Gotham actor Drew Powell are evidence of Bruce Wayne’s nascent struggle to become the vigilante Gotham City needs or… something kinkier. The helmet and spiked gauntlets in the photo certainly look like they could be early Batman prototypes, but they also bear a striking resemblance to fetish gear. Maybe Gotham’s fourth season will be just that interesting.

Photos of Bruce Wayne in a rubbery Batman prototype suit surfaced earlier this month. While none of the pieces of armor pictured individually make a Batman suit, it’s not hard to see how the set could be combined to create something approximating the familiar cape and cowl. The top-left piece of armor in Powell’s image looks to be the closest thing to a recognizable piece of Batman attire – the spiked tiara has a distinct set of pointed ears.

A recent report confirmed that Lucius Fox will be making Bruce Wayne’s armor in the upcoming season, bringing the character a little closer to his Dark Knight trilogy incarnation. The pictured gear doesn’t really look like a Lucius Fox creation, though. As with all teasers, fans are left to wonder exactly what they’re looking at. Is this Lucius’ contribution to Bruce’s nocturnal outings, or something far more mysterious? If it is Lucius' work, perhaps it's from his... personal collection?

Gotham’s fourth season returns to Fox on Sept. 21. The series is a production of Primrose Hill Productions starring Ben McKenzie, Donal Logue, David Mazouz, Zabryna Guevara, Sean Pertwee, Robin Lord Taylor, Erin Richards, Camren Bicondova, Cory Michael Smith, Victoria Cartagena, Andrew Stewart-Jones, John Doman, Jada Pinkett Smith and Morena Baccarin.
