Agents of S.H.I.E.L.D. and Daredevil may both be a part of the MCU (not like the movies like to admit it), but they couldn't be more different as shows. One is a secret agents procedural that now includes a heavy supernatural element, with alien worlds and Inhumans, while the other is extremely dark and grounded. Still, every now and then they'll acknowledge they're in the same universe, even if a direct crossover is massively unlikely if not impossible. Here, we see a motorcycle club called Dogs of Hell, with it's members tooled up and ready for action. They appeared in a Season 1 episode of Agents of S.H.I.E.L.D., based in Nevada and led by a man named Rooster, facing up against Lady Sif and S.H.I.E.L.D. They haven't been seen since, so it'll be interesting to see if this is the same gang and they've relocated to New York, or whether it's just another branch. Either way, they won't be good news.
