The Emperor is not as hostle toward other xenos as the Imperium believes, for example, the Emperor would hypothetically work with Tau, Eldar, minor xenos species, and even Szarekh's Necrons if there was a greater threat. But the Emperor would NEVER work with Chaos, since Chaos would mislead and trick him, and in the end destroy all the Emperor has worked for.
