Shirt

The Shirts, known in Japanese as Shatsu, are a humanoid alien species that inhabited Planet Shikk before their extermination by the Saiyans. Their name follows the clothing-based naming theme applied to several races in Dragon Ball, with "Shatsu" being the Japanese word for "shirt." In Dragon Ball FighterZ, the species is alternatively referred to as Shikkian, derived from their planet's name.

Physically, the Shirts appeared similar to Earthlings in most respects, standing at roughly average human height. Their civilization was advanced enough to field soldiers with weapons, and they were governed by what appeared to be a young boy or childlike emperor. Beyond these brief glimpses, almost nothing is known about their culture, technology, or society, because nothing survived long enough for anyone to document it.

The Shirts appear in a flashback depicting one of the many planet-purging missions carried out by Saiyans under Frieza's command. Vegeta, Nappa, and Raditz attacked Planet Shikk and slaughtered its inhabitants, including the armed soldiers who attempted to resist. The Shirt soldiers, despite their best efforts, were hopelessly outmatched by three Saiyans who considered the assignment routine.

This flashback is significant not for the Shirts themselves but for what it reveals about the Saiyans' lives before Earth. The casual, businesslike nature of the mission underscores that Vegeta, who would eventually become one of Earth's greatest defenders, spent years systematically exterminating entire civilizations without hesitation or remorse. The Shirts are one of countless races who existed, fought back, and were erased from history by the Frieza Force's planet-brokering operation.

The Shirts have no surviving members, no cultural legacy, and no lasting impact on the Dragon Ball storyline beyond their role in illustrating the brutality of the Saiyan-Frieza alliance. The soldiers briefly seen in the flashback bear a visual resemblance to members of the Gurumes Army and the Rabbit Mob, suggesting that Toriyama recycled certain character designs for these expendable background figures.

In a broader sense, the Shirts represent every unnamed civilization that fell to the Frieza Force's expansion. For every planet the heroes eventually saved, there were dozens like Shikk that were destroyed before anyone powerful enough to stop it even knew or cared. The Shirts are a reminder that the Dragon Ball universe's history is built on layers of tragedy that the main characters can never fully atone for.
