As GI Joe‘s ‘Ninja Force’ story arc comes to a close, things take an unexpected turn. Writer Larry Hama had previously dismissed G.I.JOE VS THE TRANSFORMERS (1987) as being outside of G.I.Joe continuity, but in this story he takes a full u-turn and confirms that the Joes categorically share their universe (Earth-91274) with the Transformers.
The inclusion of the Robots in Disguise was to promote the new Transformers: Generation 2 series (as well as the new G2 toy line). But it seemed the golden age was over for both G.I.Joe and Transformers, as far as Marvel was concerned. By the end of 1994, both ongoing titles were canceled. The characters would later return under other publishers and gain new levels of popularity and acclaim.
The story itself feels like it’s been written under editorial duress. Snake Eyes now leads a band of brightly coloured ninjas called Ninja Force. Scarlett is pretending she’s defected to Cobra – not that anyone believes her. Destro and the Baroness are actually defecting to G.I.Joe. And as for those oversized Cybertronians, their story ended some time ago with the Autobots defeating the Decepticons and the Ark crashing back to Earth with Megatron on board. Of course everyone assumed he was dead… for all of five minutes.
Crossover: Hopping between the two titles and a special, War Without End counts as a crossover.
Title: Not an official crossover, the Omniverse Comics Guide has named the event ‘War Without End’ after the story featured in Transformers: Generation 2 #1.
Series title: While the title of the G.I.Joe series appears to be ‘G.I.Joe featuring Snakes Eyes and Ninja Force’, I’m going to stick with calling it ‘G.I.Joe: A Real American Hero’ to avoid any confusion in terms of the continuity the series is set in.
Must Read: Essential follow-up reading to this event is marked with a ✔ in our Fallout section.
