Group Spotlight: Dogs of Hell

Five years ago, almost to the day (March 11, 2014), Agents of SHIELD aired the episode "Yes Men". The episode is notable for a full-on guest appearance by Sif - not just a cameo like with Nick Fury - and for being an early hint that Ward is a bad guy, but it's also notable for introducing the Dogs of Hell to the Marvel Cinematic Universe.

The Dogs of Hell are a motorcycle gang the the villain of the episode, Lorelei, is able to take control of through the hypnotic powers of her voice. This was their only appearance in Agents of SHIELD, but not their final appearance in the MCU. A different branch of the club played a major part in Daredevil season 2 (March 2016) as one of the three participants in the gang war that season revolves around. They later had brief appearances or mentions in The Punisher (November 2017) and both seasons of Iron Fist (March 2017 and September 2018).

Here's where it gets fuzzy. The Marvel Wikia claims that their first appearance in comics is in Civil War II: Kingpin #2 (August 2016). This would make sense, being only a few months after they were so prominently in Daredevil. And a biker gang DOES appear in that issue, but I can find no indication that they're actually the Dogs of Hell. If anyone can corroborate that information, let me know.

But that's all right, because they definitely do appear by name in The Immortal Hulk #1 (June 2018).

This is honestly my favorite kind of canon immigrant. It's not there to promote anything, it's not driven by any kind of nostalgia, it's just the comics realizing an adaptation filled a gap in some way and continuing to use it because it makes sense. Marvel never had a reoccurring motorcycle gang before. Now they do. And if they want, they can get a lot of mileage out of that.
