The original Tuna vs. Earth Defense Force series.
About
Year: Probably the near future. One day, a massive swarm of mysterious flying objects approached Earth from outer space. Humanity was terrified. Were they aliens? Unknown lifeforms? Or perhaps an extraterrestrial race with a highly advanced civilization? —They were wrong. It was tuna. However, they were no ordinary tuna. They were descendants of tuna that had existed on Earth long ago, ventured into space, and underwent their own unique evolution over countless eons. And they had only one objective: The invasion of Earth. Thus began the greatest war in history between humanity and the evolved tuna. You are members of the Earth Defense Force, TBG (Terrestrial Battle Guard), deployed into the fight against the tuna legion. Note that the higher-ups have given absolutely no thought to your survival rate. "Gentlemen, protect the Earth." —They are absolute monsters. But you are all the Earth has left. The battle for the future of humanity begins now. ...Even if the enemy is tuna. Good luck.

Tuna that have invaded Earth. They are actually descendants of ancient Earth tuna that mutated, developed a super-civilization, and migrated to space. As soldiers, they rarely engage in hand-to-hand combat, instead operating the Tuna Army's weaponry. Their primary weapons include the "MA-GU-RO," a 12-meter tall bipedal weapon capable of firing plasma cannons, and "Gunships," unmanned UFOs that fire lasers. They attack with overwhelming numbers but are not invincible. Their flagship is the super-massive space battleship "Maguro," which bombarded the surface with lasers upon arrival at Earth. Every tuna soldier's catchphrase is "Magu." Apparently, they are inedible.
