OPA Tattoo

The OPA Tattoo, a split circle emblem embodying Belter nationalism and defiance against Earth and Mars, emerges in Leviathan Wakes as a bold symbol of the Outer Planets Alliance's resistance, often inked on skin or worn as badges by revolutionaries like the crew of the Rocinante. Across The Expanse series, it evolves from a gritty marker of fringe rebellion to an emblem of fragile legitimacy as the OPA transitions into a recognized political power post-Rockhopper incident and Eros crisis. By later books, the tattoo signifies both enduring Belter identity and the tensions of interstellar governance, appearing on diplomats and militants alike amid escalating conflicts like the Free Navy uprising.
