Pym still believed that Kang was responsible for his breakdowns in Avengers Forever. So if Kang had already shot down that theory prior to that, I suspect Busiek made the same mistake I made.
But yeah... in the end it did overshadow the plot. I've made this complaint before... that Mighty Avengers title was a good book, but not a good Avengers book. It was a Hank Pym book. And perhaps part of the problem is that clearly Avengers Academy isn't that. It's about the students first and foremost. So Hank and his issues have to sort of take a back seat.
The one who was replaced (and still is) was Wanda... though not a Skrull, and the replacement Wanda doesn't know she's a replacement.
He's barley been in SA, but even in his few panels i much prefer him there. With his banter with Beast, and the Lighthouse and his Pymporter (LoL). In which he does live testing on Cap Britain (LoL).
I hated the Wasp name, but I like the costume and the gear that came with it. And he chose arguably one of his weaker identities to stick with. Yellow Jacket and Wasp could both grow, but additionally had flight and lasers. But Giant Man just kinda grows. That's kinda weak.
the stupid fucking hipsters (if you can call them that) don't really do continuity....so they'll prob have some snarky...if not smart....comment to make.
Later, Pym relaxed a lot more, and he was more confident with himself. He started toying with silly, crazy, things, like capturing Loki and inviting him to be an Avenger. The craziest being setting up his Infinate Mansion, in what he thought was Janets body in Overspace. But going to Eternity to be given the job of Scientist Supreme seemed to stroke Pyms ego overly too much, and smacked of being a sub-conscious craving he wanted quenched.
