In order to gain access to this fight you must first clear out Eos and set up a colony which is the first Priority Op (main mission) once you get your ship, the Tempest. It’s hidden behind a side mission that you may think nothing of, but its rewards are worth the effort. One such boss is the Remnant Architect on Eos. Some will stay hidden, allowing you to beat the game without ever facing their monstrous presences. There are some bosses in Mass Effect: Andromeda that don’t just appear right away.
