With Dr. Strange, Valkyrie, Nighthawk, and Yellowjacket captured by the Sons of the Serpent, Bruce Banner (a.k.a. the Hulk) knew he needed help thwarting the foes. As a result, Defenders #24 became the first in a two-part reunion, of sorts, bringing back several additional allies of the team.
In her first attempt at using the Crystal of Agamotto, Clea got the ball rolling by telepathically summoning several heroes who had lent a hand to the non-team in the past. The effort worked, and Daredevil, Power Man, and Daimon Hellstrom arrived to accompany the Hulk against the villainous organization.
I like this issue for accenting the history and dynamics of the team. Yet for all its strengths, Defenders #24 invariably reminds me of Giant-Size X-Men #1, in which Professor X used his Cerebro technology to telepathically summon mutant allies to help Cyclops rescue the original X-Men. With a May 1975 cover date, that milestone X-Men adventure appeared one month before this issue of the Defenders.
