Comic book fans already knew that, considering the group has had a rotating cast of heroes populating it over the years, but Jeph Loeb took things a bit further to imply the original TV miniseries’ lineup didn’t consist of the official Defenders.
Loeb reminded EW that the hero lineup was never referred to as “The Defenders” in Season 1 or in any of the other series, and nor did they have matching outfits or any other signifying branding.
Which would seemingly mean the Marvel team could technically be made of any “defenders” even outside the initial foursome.
Jeph Loeb went on to explain that there are several iterations of the Avengers squad, so it’s not out of the realm of possibility that there are several Defenders member lineups as well.
