In G.I. Joe: A Real American Hero #228, Hama (and regular artist S.L. Gallant) embarked on an unusual plot by utilizing an all-female cast, with appearances by virtually every living female character he's used (with the exception of Grunt's wife) and introducing a number of new female characters. There are literally no male characters in this issue.
Part of the story continues a subplot about the Cobra forces as Baroness and Zarana (the two female Cobras with action figures) train the recently-recruited Dawn Moreno. There's also a continuation of an ongoing subplot about Duke's wife, Claire Hauser, who was recently reunited with Duke after being believed dead for years - but it seems Claire may be one of the many people Cobra has brainwashed and she ambushes the Joes' ally Jane. In another subplot, the recently-introduced Joe Bombstrike (a character who had appeared in other comics but only just began appearing in Hama's stories) goes after a Cobra lab being run by Dr. Sidney Biggles-Jones and Dr. Cassandra Knox. In yet another plot, the Joes Scarlett & Jinx visit Storm Shadow's aunt Obake Obaasan and we're introduced to a female Red Ninja named Akane, who has some kind of a grudge against Jinx.
Finally - and most compellingly - Cover Girl returns to duty after a recent throat injury, giving her a rough voice. Although Cover Girl was the 2nd female Joe to receive a figure, she's never amounted to much in Hama's stories - perhaps her voice can be her "thing?" Anyway, Cover Girl and Lady Jaye go to see the mother of a deceased Joe named Shooter and present the medals Shooter had earned to the mother. Shooter was a character who existed very deep inside G.I. Joe lore, primarily as an in-joke about Marvel Comics editor Jim Shooter. In G.I. Joe: Declassified, Hama established Shooter as a female sniper who was a "secret" member of the Joes in their earliest assignments but died early on without the Joes even realizing her involvement in their work. I loved Hama's story about Shooter (Declassfied is a forgotten masterpiece) and having the cast finally get to acknowledge her sacrifice and help Shooter's mother cope with her death was a great idea. The scenes about Shooter justify the entire concept of an all-female issue of G.I. Joe. Well done Hama!
