SPOILER WARNING: This article contains spoilers for "Uncanny Avengers" #10, which is on sale now.
Last month's issue of "Uncanny Avengers" picked up where the 2015 OGN "Avengers: Rage of Ultron" left off. Newly merged with his villainous creation Ultron, Hank Pym arrived back on Earth and attempted to pick up his life where he left off. That included teaming up with the Avengers and even getting a burger for the first time in months. But the Avengers Unity Squad wasn't sure they could trust Pym following his merger with an artificial intelligence that had tried to kill them dozens of time in the past. Captain America called in Hank's ex-wife Janet Van Dyne, the Wasp, for assistance.
Gerry Duggan and Pepe Larraz's "Uncanny Avengers" #10 picks up the action, with Hank Pym seemingly integrated into the Squad's membership; he helps the team battle rampaging demons in a New York City subway station. But Hank isn't the only hero helping them out: the Wasp is too, sporting a new look. But Wasp's role isn't just to help fight demons -- she's also there to test out Pym.
When Pym fails to catch Jan's "Ghostbusters" reference and says he would like a trip to the beach, the Wasp knows something's up. Tipped off that Hank Pym may not be who he says he is, Cable pushes the "Avenger" further than anyone else by questioning the scientist's importance. That's when Hank Pym makes a startling reveal: he's much more Ultron than the team had imagined.
Wasp's theory is that Ultron murdered Hank and is now wearing his face, and the issue leans into that theory pretty hard. The issue doesn't firmly answer if anything of Pym is left inside the cyborg's body or mind, but it's clear that the merged Ultron/Pym entity is no friend of the Avengers. Ultron/Pym also doesn't deny Jan's theory when she states it to the villain's face, further indicating that Hank Pym is truly, totally gone.
"Uncanny Avengers" #11 arrives on July 27.
