I don't think he did. He's Athena's champion, and since Herc and Cho are hanging out with Athena, they're gonna run into him soon. Unless he is dead and part of their mission in Hades is to retrieve him too.
Yeah, the Agents control the Atlas Foundation, which is known as a vast criminal empire on par with HYDRA or the Hand. That's the central conflict of the series--Jimmy Woo trying to use the Atlas Foundation for good but in very discreet ways. I love how much more animated Parker makes him on Bob Grayson's ship, since it's the only place he can really be himself.
Anyway, the Dark Reign stuff I read all looks fantastic. The Secret Warriors solicitation made me decide to just pick up SW #1 and read the issues instead of trade-waiting, in fact. I want to get a feel for Hickman's non-indie writing and he and Bendis would have to really, really be trying hard to f*** up Dum Dum Dugan's return.
