Eos Elara

Eos, a character in the Across the Void series, is Main Character's brother. He is first seen in Chapter 1.

Appearance
Eos has olive skin with pink streaks, black hair with blue streaks, and blue eyes. He wears a pair of googles around his neck and a blue button jacket with light blue streaks.

Personality
Given his status as a Vanguard Marshall, he upholds the law and tries to settle conflicts peacefully. He detests the Jura and refers to them as "glorified murderers". Because of this, he is shown to be hypocritical given that he refuses to acknowledge that Heze is a war criminal.

Main Character
Main Character states that he is overprotective, but he counters this by stating it's his job as your older brother to be worried. He says he built his life around MC and Pax, and wouldn't be on the Atlas if he hadn't. If you hand Heze over to the Jura, he will express his disappointment and says that he can't respect your decision. Since he is not part of the Atlas crew, he doesn't tell MC about his Vanguard mission or duties (such as, escorting Senator Tauri to the capital), which hurts MC's feelings but MC publicly pretends it doesn't. Privately, MC angrily tells Eos that he put the crew and passengers in danger; Eos tells MC that he did it to protect Lyra, not to hurt MC.

Pax Elara
It is stated by Main Character that Pax and Eos always bicker with each other, forcing MC as the middle child to mediate. Pax becomes upset with Eos when he calls the Vanguard (and Admiral Deimos comes aboard) around the same time she tries to smuggle a Jura agent. Eos tells Pax that he didn't do it to hurt her; he only wanted to protect Lyra. However, Pax believes he cares more about everyone else than he cares about his family, that he acts like he has to fix her and doesn't accept her for who she is. Eos counters that she doesn't take responsibility for anything, and that she abandoned both him and MC when she left Cyber.
