"This was your grandfather's. He was one of the Navy's first frogmen during World War II. [...] But after the war, his country forgot about him. So, he went back to the sea, scavenging and surviving with his wit... and this knife."
Jesse Kane to David Kane about the knife of his father.[src]

World War II[1], or the Second World War (often abbreviated as WWII[2] or WW2), was a global war that was under way by 1939 and ended in 1945.

This war involved a vast majority of the world's nations—including all of the great powers—eventually forming two opposing military alliances: the Allies and the Axis. Various advanced weapons were made during the war, and the Axis conquered many countries in Europe, Africa, and Asia.


"Germany is an immensely proud nation. They will never surrender."
Sir Patrick Morgan[src]

In 1918, Ares predicted that Humans would have continued to making warfare, in particular Germany as he previously had mentioned that it was a proud nation.[3] This proved to be true when Adolf Hitler rose to power and provoked World War II.


Outbreak of war

The conflict began on September 1, 1939.[4]

Wonder Woman fought in the conflict.[5]

During the conflict a fighter plane remained buried in Greenland.[2]

Louvre Museum raid

On June 12, 1940, the Nazis invaded Paris and the Louvre Museum.[6][4]

America's involvement

Pearl Harbour

The United States of America entered in war after the Attack on Pearl Harbor, a event who, like many during the wartime, was recorded by the Daily Planet.[7]

Many American soldiers sailed from Tricorner Yards in Gotham City to Europe to fight in the conflict.[8]

According to Amanda Waller, during the war, the USA Navy collaborated with the Mafia.[9]

The grandfather of David Kane fought in World War II as one of the Navy's first "frogmen" (code-named "Manta" for his stealthiness). It is not known how well he performed, or what exactly he did during the war, but based on Jesse's testimony, his deeds apparently earned him the respect and admiration of his peers.[10][11]

Metahuman experiments

At some point, the Nazis built their prison and laboratory Jotunheim in Corto Maltese to transform political prisoners into some of the earliest known Metahumans, which they then used as weapons.[12]

End of the war

On September 2, 1945, World War II ended following the defeat of the Nazis and other Axis powers, including Japan.[4][7] Soon after this, the Nazis abandoned Jotunheim completely.[12]


After the war ended, the United States of America decided to forget about what "Manta" had done during the war; and thus, he returned to the sea and survived by scavenging and using his wits.[10]

On May 30, 1948, the Fawcett Central School set up a war memorial to honor the teachers and students of the school who served in the war during 1939-1945.[13]

After the Nazis abandoned Jotunheim, Corto Maltese leader Silvio Luna had taken Jotunheim and continued using the fortress for its experiments and prisoners.[12]
