The Defenders: 30 Best Easter Eggs In Netflix's Marvel Universe (So Far)

22. The Dogs Of Hell

The Dogs Of Hell actually turn up twice in the Netflix universe (as do Marvel mainstay companies like Roxxon as background detail).

The gang, which first debuted in Agents Of S.H.I.E.L.D. episode 'Yes Men' - the 15th episode of season one - in which Agent Coulson was forced to fight some of their members by Asgardian villainess Lorelei, turn up in Daredevil season 2 and then in Iron Fist.

They're mentioned as a continued part of New York's crime family, despite suffering huge losses in Daredevil at the hands of The Punisher.
