Jane Foster reflects on the great losses of her life—losing her mother to cancer, losing her father later on, and the death of her ex-husband and son—while sitting in the hospital. On Asgardia, the Odinson and Odin himself battle the Mangog with all of their might. However, all of their power isn't even staggering the beast. Loki arrives to try and save Fridja, but she will not abandon her people.
The saga of Thor takes a yet darker turn with #704. It's shown that not even the might of Odin can stop the Mangog, and Jane relives the helplessness she has felt at losing her family throughout her life.
We do get to see the resolve of Jane Foster and how she has lived her life. Her mother pleaded with her to find a god to believe in before passing, but Jane never did this. Even now, she knows not to rely on outside forces. She must take agency, and this is the attitude she will take in fighting cancer.
The battle scenes between the remaining gods of Asgardia and the Mangog are fittingly epic. We get some internal monologuing from Odin that shows that he is all-in on this fight, even if he is unsure if victory is even possible.
Loki's visit shows some compassion for his family yet remaining in the God of Mischief.
The ending gives the story a final turn that is a bittersweet mixture of triumphant, satisfying, and heartbreaking. You could probably guess what it is, but I'll not spoil it here.
Russell Dauterman's artwork continues to be a great fit for The Mighty Thor. The battle tapestries are gorgeous, the impacts are felt, and the playing with the set-dressing and layouts are clever. While the modern Loki design is certainly more derived from Tom Hiddleston's appearance as Loki in the films, Dauterman has the Trickster God's face near-perfectly modeled after Hiddleston here. It's not a bad thing either. Matthew Wilson's color art is still a gorgeous mixture of cosmic, psychedelic, and fantastical when in Asgardia. This is cleverly balanced by the plain whites and muted colors in the hospital that holds Jane Foster.
Thor #704 is a high-action and emotionally resonant entry that pushes further "The Death of the Mighty Thor." You're left wondering if the events will truly match the name of the story while watching your beloved characters grapple with grief, mortality, and a hulking, god-killing beast. Dauterman and Wilson's art backs up Jason Aaron's story perfectly, and the book is definitely recommended. Give it a read.
