I haven't seen anything with these characters since Chaos War for Amadeus and the cross-over bogged down Herc series that only lasted 10 or so issues.

Has anything been done with them more recently? I really liked the Pak/Van Lente Incredible Hercules series.

Cho was most recently in the Savage Wolverine series set i the Savage Land

Herc has popped up in the major events just in minor roles
In Fear Itself he battled Kyknos who was trying to rez Ares. In Spider Island Herc becomes a Spider Hybrid and shacks up with Archane (Not the Julia Carpenter one but the one from myth) and in A vs X he was an instructor during the Avengers Academy tie ins
