Mikasa and Levi are both Eldians in the Attack on Titan series. Although they may not possess the power of the Founding Titan like some other Eldians, they are still part of the Eldian race.
In the world of Attack on Titan, Eldians are a specific ethnic group that possess the ability to transform into Titans. They are descendants of Ymir Fritz, the original Titan who gained the power of the Titans. Eldians are generally discriminated against and segregated from the rest of society due to the fear and prejudice surrounding their Titan abilities.
Mikasa Ackerman is of mixed heritage, with an Eldian mother and an Asian father. Despite her mixed bloodline, she is still considered an Eldian due to her mother’s ancestry. Mikasa’s Ackerman lineage also grants her enhanced physical abilities, making her a formidable fighter.
Levi Ackerman, on the other hand, is of pure Ackerman bloodline. The Ackermans are a unique group within the Eldian race, known for their exceptional combat skills and resistance to the influence of the Founding Titan’s power. While they are still Eldians, the Ackermans do not seem to be affected by the Founding Titan’s ability to control the memories and actions of other Eldians.
It’s worth noting that being an Eldian does not necessarily mean one possesses the power of the Titans. The Eldian race is a broader ethnic group, and not all Eldians can transform into Titans. The power to transform into Titans is limited to those who inherit one of the Nine Titans, such as the Attack Titan or the Colossal Titan.
Despite not having the power of the Titans, both Mikasa and Levi have been shown to be transported to the “paths” realm, where Eren Yeager, who possesses the power of the Founding Titan, can communicate with other Eldians. This suggests that being an Eldian is a prerequisite for accessing the paths, regardless of whether one possesses a Titan power or not.
Mikasa and Levi are indeed Eldians in the Attack on Titan series. Their lineage and involvement in the Eldian race are integral to their characters and the overall story. While they may not possess the power of the Founding Titan, they are still affected by the events and consequences of being Eldians in the world of Attack on Titan.
