Question

Who is Jar Jars brother

Answer 1

If you mean Jar Jar Binks from Star Wars: there is no officially named brother in Lucasfilm canon. Jar Jar’s family is barely documented in the films and series, and no canonical sibling is identified. If you’re thinking of a specific comic, novel, fan story, or Legends (non‑canon) source, tell me which one and I can check whether a brother appears there.
