Before Brunnhilde

At the request of Winston Churchill, several Golden Age heroes joined forces to battle the Axis Powers in Invaders #1, retroactively set in late December 1941.

Although Captain America and the original Human Torch had second-thoughts about calling themselves the Invaders, proposing alternate names ranging from the Protectors to the Revenge Squadron, Sub-Mariner convinced the team to use the term that Churchill suggested.

Soon after they arrived in Europe, the Invaders encountered a mysterious woman with golden eyes and only a vague recollection of her past. But the woman soon recalled that she was a marooned extraterrestrial who had escaped from the clutches of Nazi villain Brain Drain (Invaders #2).

As an homage to the Richard Wagner opera, Brain Drain had called the extraterrestrial woman Brunnhilde. But her actual name was MCM-XLI (the Roman numeral MCMXLI translates to 1941), and she despised being objectified as a legendary valkyrie.

Lacking the willpower to escape on their own, three male extraterrestrials still remained under Brain Drain's mental control. They answered to the names Donar (god of thunder), Froh (god of lightning), and Loga (god of thunder).

Though set in the past, Invaders #1-2 were published the same months as Defenders #26-27 (August-September 1975). The superhero Valkyrie was well-established by this time, but her identity as the real Brunnhilde went unrevealed until Avengers Annual #11.

Roy Thomas wrote Invaders #1-2. Frank Robbins illustrated those issues.

Angst-Ridden

Following a jaunt through some of the most absurd corners of the multiverse, She-Hulk and traveling companion Howard the Duck encountered a band of villains who originally battled the Defenders (Marvel Treasury #12).

Led by the mystical Dr. Angst, the reunited team of villains also included Tillie the Hun, Black Hole, Spanker, and Sitting Bullseye—but with updated costumes (Sensational She-Hulk #16-17).

Together, the obscure criminals sought to dominate the Insipiverse, a world of all-pervasive spiritual torpor, aesthetic monotony, and intellectual inertia.

She-Hulk and Howard foiled the plot.

Steve Gerber wrote The Sensational She-Hulk #16-17 (June-July 1990). Bryan Hitch pencilled those issues.

Postmortem Mall

In the midst of a near-death experience, She-Hulk found outside a 67-story-tall purgatory called the Postmoderm Mall (Sensational She-Hulk #53).

Touring this comedic afterlife with Bucky Barnes (Captain America's sidekick during World War II), She-Hulk spotted heroes and villains alike. Mimic retained the iconic powers of the original X-Men, which he had lost by the time of his apparent death (Incredible Hulk #161).

Several adversaries of the Defenders perviously targeted by the Scourge of the Underworld also occupied the entertainment complex, including Ringer, Miracle Man (now working in the mall as a hairstylist), and Melter (taking a fitness class along with Nighthawk, mourned in Defenders #107).

Flag Waving

The baron of Yinsen City was dead. Hostile invaders from Mondo City were invading the utopian metropolis, and the Defenders were all-but stripped of their powers.

Only through the diplomacy of outsider Captain Britain (Dr. Faiza Hussain) did the two domains achieve a state of peace (Captain Britain and the Mighty Defenders #2).

Out of appreciation, the Defenders gave Captain Britain a flag, with a design drawn out of their own fragmented memories. Yet the heroes had no clear recollection of Great Britain or the symbolism of the British flag.

Captain Britain: … Right now we all get to decide what it means.

Had their memories been intact, the heroes might have known that the flag of Britain combined the red cross of St. George (patron saint of England), the white saltire of St. Andrew (patron saint of Scotland), and the red saltire of St. Patrick (patron saint of Ireland). Each of these saints is steeped in lore, such as the legend of St. George slaying the dragon and the legend of St. Patrick driving the snakes out of Ireland.

The Mighty Defenders

The multiverse was destroyed!

The heroes of Earth-616 and Earth-1610 were powerless to save it!

Now, all that remains is Battleworld!

A massive, patchwork planet composed of the fragments of worlds that no longer exist, maintained by the iron will of its god and master, Victor von Doom!

Each region is a domain unto itself!

Something was amiss in Yinsen City well before a costumed figure called Captain Britain illegally entered the walled metropolis. Like Captain Britain (Dr. Faiza Hussain), the Defenders who protected that domain had vivid dreams that they were in fact following in the footsteps of deceased heroes (Captain Britain and the Mighty Defenders #1).

Spider Hero (Hobie Brown), for example, had a vision that he gave up his pervious guise as the Prowler following the death of the original Spider-Man (Peter Parker).

Rescue (Ho Yinsen, baron of the city), dreamt that he had invented his suit of technological armor with a dying Tony Stark. (In the original Marvel continuity, it was Yinsen who died after helping Stark build his Iron Man armor in Tales of Suspense #39.)

Other Defenders in this timeline included Kid Rescue (Antonia Yinsen, the baron's daughter), White Tiger (Ava Ayala), and She-Hulk (Jennifer Walters). Also the Thor if this domain, She-Hulk carried a gavel instead of a hammer (suggesting her former career as an attorney).

As an aside, Prowler and the original White Tiger (Hector Ayala) were both Defenders for a Day.
