Disclose Notes: Possible Stein inks per Mark Evanier and Nick Caputo. Although Stein had conversations with Greg Theakston denying he inked any Challengers stories it's possible Stein forgot he worked on them. It also looks like Kirby inked a few pages on his own. Possible Wood script and Kirby revisions per Mark Evanier and Nick Caputo.

The robot-duplicates are similar to Life Model Decoys (LMDs) used by S.H.I.E.L.D. in Marvel comics also drawn by Jack Kirby.

June convinces him "Wars never solve anything!" and ULTIVAC agrees to a televised public hearing, and pledges to help humanity. Hesse blasts ULTIVAC and Rocky - who dies on the operating table, as foretold. June offers to take Rocky's place, and the Challs agree, until Rocky miraculously revives.
