The four-issue mini-series Black Widow and the Marvel Girls is collected, along with Amazing Spider-Man issue #86 from 1970, as Black Widow and The Marvel Girls GN-TPB
. The mini-series features adventures with a variety of fellow-Avengers and other characters, as we see the Black Widow bonding with her new team-mates, and we also get a glimpse of her origin in this Marvel Universe. They are excellently scripted and illustrated stories, and would not be out of place in the `real' Marvel universe.
Issue #1 sees the Black Widow breaking into (and out of) the base of an international arms dealer, which is intercut with her younger days at the `Red Room' training facility, where the Enchantress takes an interest in her upbringing and training - "I'm bored. Bored as only an immortal can be, and I saw an opportunity to cause a few explosions."
Issue #2 sees the Black Widow and the Wasp making their undercover escape from Latveria, after Doctor Doom set a trap for the Avengers in the hope of stealing the Vision. The Wasp gets to bond with the new girl on the team, as Black Widow's espionage skills help get them and a captured Doombot out of the country.
Issue #3 sees the Black Widow investigating the new super-powered female Captain (Carol Danvers) Marvel, as they team up to hunt for one of the Red Skull's Sleeper agents on the loose in Israel.
Issue #3 sees the Black Widow and Storm of the X-Men teamed-up with the Mole man to hunt for a kidnapped senator being held by a rogue faction of Moloids who have become a New York street gang.
Amazing Spider-Man #86 guest-stars the Black Widow, in the story which saw her transform from her `old' femme-fatale character and costume into the 1960s cat-suited spygirl that she has remained to this day. Ah, the 1960s, the decade that never dies. I remember it well - I was too young then to have forgotten it.
