Badoon
The Badoon are a reptilian alien species in the fictional Marvel Comics universe. They are notable for living under strict gender segregation, resulting in two separate societies; the Brotherhood of Badoon (ruled by a "Brother Royal") and the Sisterhood of Badoon (ruled by a Queen).
The Brotherhood live on the planet Moord in the Lomora star system while the Sisterhood reside on the Badoon homeworld of Lotiara ( Capella II, also known as "Swampworld"), 42.2 light years from Earth.
