The Defenders was one of my favorite comics series growing up in the '70s. I loved that the team included the Hulk, but it also introduced me to other cool characters like Valkyrie, Hellcat, and Nighthawk. I've always wanted to go back and explore the roots of the team, even though the Doctor Strange, Namor, and Sub-Mariner line-up isn't as exciting to me.
One thing that always confused me was the team's insistence that it's a "non-team." By the time I started reading their adventures, they very clearly were a team by every definition I knew. Their origin makes sense of their denial though and it's pretty fun. The seeds of their earliest adventures are planted in the individual series of each character with some shared villains and then especially in the pages of Sub-Mariner (the first adventures to be collected in this volume) where Namor, Hulk, and the Silver Surfer team up for the first time.
In the Marvel Feature anthology series, Doctor Strange contacts Namor for help on a mission and Namor suggests also getting Hulk and Surfer. Surfer excuses himself, but for three issues of Marvel Feature, Strange, Namor, and Hulk help each other out on various challenges. They're very much not a team, but just acquaintances who occasionally get each other's back. During their first team up, Namor uses the word "defenders" to describe what they did and Strange likes the word. He proposes it as a name if they should ever have to team up again, but Hulk makes it clear that he doesn’t want to. After his experiences with the Avengers, he hates being on a team. Namor also doesn't seem interested.
After three successful issues of Marvel Feature, The Defenders got its own series, continuing the occasional team-up pattern, but with Surfer quickly being brought back into the mix. Valkyrie is also introduced much earlier than I expected her to be.
While trying to help Surfer escape Galactus’ barrier around the Earth by taking him through another dimension, Strange accidentally takes the group into the realm of an old enemy and finds a woman that he'd abandoned there on a previous adventure in his own series. He rescues her, but her separation from the godlike being causes her to go insane. I'll get back to that in a second, but it's funny that Strange realizes that the entire endeavor has been a massive failure and questions his leadership ability. Not that anyone has ever actually appointed him leader. He just seems to have assumed it.
When the group returns to Earth, they're immediately whisked into another adventure involving a magical realm ruled by a ruthless queen. They're imprisoned by the Thor/Avengers villain, the Executioner, who has fallen under the queen's spell and has also imprisoned his usual partner, the Enchantress, and her latest conquest the Black Knight.
Enchantress’ magic can’t help her escape directly, but she’s able to imbue Strange's insane rescued woman with the spirit of the Valkyrie so that Valkyrie can escape and take the others with her. The heroes (and Enchantress) overthrow the queen, Enchantress and Executioner renew their former alliance, and when Black Knight complains about that, Enchantress turns him to stone and leaves with the Executioner. Strange returns the others to the normal world and vows to one day figure out how to restore the Black Knight. Valkyrie - still inhabiting the insane woman's body - wins over the Black Knight’s winged horse Aragorn and asks to join the Defenders.
Namor protests that the Defenders aren’t actually a thing and he's right. Strange is the only one who keeps using the name. Even so, he condescendingly questions Valkyrie’s usefulness to them and I don’t really like Strange in the series so far. He seems for some reason not only to need the team to exist, but also to be in charge of it.
He does at least invite Valkyrie to stay at his place until she figures out what to do, so she participates in the last couple of adventures collected in this volume and solidifies her place on the team. Which is a team now, more or less headquartered at Strange's mansion. Even Namor has started to come around to the idea by the end.
With Valkyrie now on board, I'm fully invested in these adventures and am looking forward to Volume 2.
