I saw this as a child. All I remember about the movie was that it had a futuristic Sci-fi feel. It was set in space aboard a ship I believe. The main characters appeared humanoid but they had wings rolled up under their capes which then unfurled only when necessary.
In one scene, a boy was supposed to disarm a weapon and was shot many times in the back destroying his wings and killing him after he disarmed the weapon.

The Brahmins, an alien race of winged humanoids arrive in peace. They are in search of a new home on Earth, and desire peaceful coexistence, but some saboteurs among the new arrivals assassinate their leader before a treaty could be negotiated between the nations of Earth and the Brahmins. In the confusion, the assassins are able to seize power and launch an attack on Earth. Earth's best defense against their alien technology is the fighting robot Daimos
