Male. Yes, that British Empire. He has a somewhat strained relationship with France. When the Martian forces that conquered Germany crossed the borders to invade Belgium and France, King George V intervened, mobilizing forces from the Triple Entente including Canada and ANZAC troops. Initially, he charged in confidently, styling himself as the savior of Europe, but he struggles against the Martian weaponry that remains unscathed even after being bombarded by every available cannon.

Male. He feels victimized because other nations wouldn't listen to him. In 1913, he was the first nation attacked by the Martians. He was actually planning an invasion of France at the time. When a mysterious flash was sighted in a forest near Bohemia within his borders, other European nations dismissed it as a secret German experiment. To clear the misunderstanding, he dispatched investigative troops, only to engage in combat with the Martian army. Ultimately, he was massacred by the Martians and pushed to the brink of total collapse.

Male. He loves hamburgers. He initially refused to intervene, dismissing it as a European affair. However, public opinion flipped when American ships were sunk by Martian attacks, resulting in many American deaths. Eventually, former President Theodore Roosevelt turned Wilson into a figurehead and personally began recruiting volunteers, forcing the decision to join the war. Since then, he has taken on the role of supporting a depleted Europe with supplies and manpower to help them end the war.

A manned Tripod (giant Martian robot) used by the Martians. It reaches a massive height of 90 to 150 meters. It has used its numerous mechanical tentacles to sink ocean liners carrying refugees. It possesses three legs and two energy cannons at the front, which it used to demolish the Tower of London in England and the Eiffel Tower in France.

An unmanned Martian Tripod. Although classified as a small unit, it still stands at 7 meters tall. It is incredibly fast and operates autonomously. It lacks energy cannons but uses mechanical tentacles to tear people apart. Like the Heron, it has three legs. It was the first type of Tripod to appear. However, its durability is somewhat low, and it can be destroyed by autocannons, mines, or the main guns of tanks.

Aliens who invaded Earth from Mars. They are the extraterrestrial force invading Earth. They are insectoid aliens resembling a mix of a giant woodlouse and a camel cricket. They pilot the Herons.

Female. Romantic. Most of her land has been devastated by the Tripods. She plays a supporting role, such as mounting the energy cannons barely developed by the British Empire onto her Renault FT tanks. She works to halt the Martian invasion.

Male. He defended against the Martian invasion alongside France but was left devastated.

Male. Although Germany was hit first, he was attacked almost simultaneously because the incident occurred near the Austro-Hungarian border. Maps shown in the story reveal his entire territory is under Martian attack. Nevertheless, seeing a pilot from the Kingdom of Hungary coming to support British pilots during the invasion of London suggests he continues to resist, much like Germany.
