Don was inspired by an advertisement that claimed anyone could lead an invasion force, prompting him to assemble his own ragtag team to conquer the universe. Pepu and Chiku, who are aloof and obsessed with gaming respectively, joined him, although their worth to the group was uncertain. Together, the inexperienced trio sets their sights on Earth as their first conquest. However, their plans don't go smoothly as convincing over seven billion humans to accept their new overlord proves to be a challenge. Despite their failure to take over Earth, the squad lands on the planet and starts their search for a way to subjugate humanity. However, their defeat and immediate problems such as finding food and paying rent put a hold on their aspirations for galactic domination.
