Infinity War #6

Hulk’s participation in this issue is minimal, largely joining in battles and standing around in a group.

Comments on tie-ins by Rob Johnson:-

Wonder Man #15 doesn't have the Infinity War banner But it obviously *is* a tie-in. It shows WM in the battle against the Doppelgangers that spreads across the end of IW#5 and the early part of our current issue. His rage and violence fuel him in the fight. Sometimes he mistakenly attacks heroes, including some who are fighting a Scarlet Witch Dop. Then he battles his own evil Dop again and this time wins. But he's too exhausted to defend himself against more Dops.
(There are no interludes with his Earthly supporting cast this time.)

Warlock and the Infinity Watch #10 is also not bannered but equally *does* belong. It stars Thanos with only Warlock of the Watch making a background appearance. It tells of the battle between Thanos and his Doppelganger.
Thanos and Dop fight until they are interrupted by a visit from Magus with the now-empowered Gauntlet. He welcomes whoever wins to join him and then goes away. The Thani agree to unite to kill Magus and resume their battle later to see who will take his place. But the door won't let them both in. They both pretend to give up and go away, but then sneak attack each other. The Dop is winning for 2 reasons:- The post-Infinity Gauntlet Thanos doesn't have the will to kill, and we learn that Magus is empowering the Dop (who he will destroy after he wins). But then Thanos steels himself to defeat and absorb his evil opponent, to get back his old fire. He succeeds and learns all the Dop knew, including Magus' insights into Thanos' inner conflict. He prepares to face Magus.

Fantastic Four #370's opening panels depict the status at the end of IW#5:- Magus has the Infinity Gauntlet and a crucified Warlock.
Then we have some stuff not included in our current issue. Human Torch and Thing are fighting Dops. Thing is worried by how callously Torch kills them (only to be replaced by new versions). He's even able to kill an Dop of his sister Invisible Woman. Meanwhile Invisible Woman herself is exploring the Magus' fortress. She comes across Thanos fighting his Dop (above) and gives him a helping force-field hand before moving on. She then finds Mr Fantastic, Iron Man and some other replaced(?) heroes in stasis. She frees her husband but Magus detects them. Reed is astonished at Sue's new dynamism (because her Malice side is resurfacing).
Then we get a run-through of the rest of IW#6. Magus clicks his Gauntlet fingers and puts the (remaining active) heroes including Galactus in stasis as trophies. Thanos blasts his way in to Thanos' control room. Magus makes Thanos bow to him but Thanos strikes back claiming that what Magus thinks is happening isn't reality. Magus tries to make him recant. But 1 of Thanos' blasts had deliberately missed Magus and presumably hit Warlock's cross because Adam is now free and grabs hold of Magus' Gauntleted hand. He claims that the IG remembers it's earlier master. Magus and Warlock tussle over control of the Infinity Gems. The resulting maelstrom destroys Magus’ fortress, but Thanos and the heroes survive and the FF reuinite. The heroes get reality-warped. Galactus calls his spaceship to him and everyone winds up inside it. Galactus tries to outrun the reality failure but his sphere-ship is caught, and everything explodes ... and the FF find themselves at their HQ.
The rest of the issue is a new epilogue. Aggressive Sue lambasts Reed for being the only 1 to lose the fight to his Dop. Angry Johnny flies off intending to quit the team. Sue reunites with her son Franklin. Reed thinks of stepping down as leader. Puppet Master arrives to tell Thing that Alicia's been kidnapped. Devos and Paibok arrive at Earth with revived Lyja intent on vengeance.

Next up is a 2-parter in Doctor Strange, Sorcerer Supreme #46-47:-

The opening section of #46 belongs with Sleepwalker #18 within IW#5 and has been described there.
After that the mystics Agatha Harkness, Dr Druid, Dr Strange, Scarlet Witch and Shaman go to check on DrS's friends at his Sanctum but find the place overrun by minor demons controlled by another DrS (dressed like the 'superhero' Strange from DrS vol 1 #177-183), who defeats them all.

In #47 the other Strange reveals himself to be the version from Counter-Earth. He recounts his history to his captive audience including being trapped inside catatonic Eternity, escaping when Gamora 'invaded' in IW#5, and leading up to defeating the DrS's Dop, taking over the Sanctum and offering his services to Magus. The CE-DrS thinks he kills them all but DrS really teleports them all to an asteroid where they watch helplessly as the merging of 2 Earths completes.
Agatha is in a trance because her spirit is in her cat Ebony on Earth to give them a return path. But the cat is confused and beset by demons, so DrS takes his gang through a risky jump back home where they face CE-DrS and DrS-Dop. CE-DrS tries to use power he leached from Eternity but it burns him out. They send the demons and the Dop home. They leave AH to deal with any leftover demons and the other 4 teleport back to Galactus' ship.

The remaining 2 issues are really epilogues:-

Sleepwalker #19 isn't even bannered and contains a minor bit at the beginning. Rick Sheridan and Janine wake up from the Magus' trance and therefore SW vanishes. Later he tells Rick what happened in a dream.

Marc Spector: Moon Knight #44 *is* bannered and it includes a minor overlap with our issue and an epilogue as well as more MK stuff. We see MK and other heroes at FF HQ in stasis. Then FF arrive back at their HQ with no frozen heroes in it. This issue makes it clear as seen in our issue that chars have been returned to where they were before answering the Mr Fantastic Dop's call to arms in IW#1. We see the FF disposing of the Dop bodies. Then MK arrives and Alicia explains how he saved Franklin in MSMK#41, so MrF is only too willing to join forces with Dr Strange to try to cure MK of his current demonic disease.
