The Covenant Tried to kill the Elite's because the Elite's found out that the great journey was a lie.
So the Elite's joined forces with the UNSC,which ment the Elite's were now good guys,so the Covenant tried to kill them.
If you have any more Halo questions please ask me.
The covenant is an alien species in halo including grunts and elites.
Halo Wars is about 20 Years before Halo Combat Evolved. So the Elites are part of the Covenant.
In Halo 4 those Elites are apart of an old splinter cell of the Covenant that never turned away from the Covenant ideas. As you notice there are no Brutes among their ranks because the Covenant Civil War tore the two apart. The Elites that were your allies in Halo 3 returned to their planet.
The elites aren't on your side on the first mission your on the forward into dawn and you have to fight the covenant
Halo: Reach happens before Halo 3. The Elites haven't defected from the Covenant yet.
Near the end of the game, right before you have to kill Tarturus, the boss of the game. After the Arbiter and his elites kill the brutes, he meets up with Sgt Johnson who is driving a scarab. They team up to kill tarturus. after that, its team humans+elites vs covenant vs flood.
no Gravemind was the leader of the flood and that virus. The elites in halo 3 join the UNSC marines as they fight the covenant and the flood
In Halo 4, you are not actually fighting the real Covenant. Instead, you are fighting a rouge group of the Covenant known as "Storm". This rouge group still believes in the Prophets' teachings. Not all Elites are part of Storm, only the ones that still believe.
In Halo 4 there are two species of enemy. The Covenant and the Prometheans. The Covenant consists of grunts, jackals, skirmishers, elites, and hunters. The Prometheans are the crawlers, knights, and watchers.
Short answer: bad. In Halo: Reach the Elites (Sangheili) are fighting for the Covenant. This is rather confusing to many players as they were allied with the UNSC in previous Halo games, but keep in mind that Halo: Reach is set before even the first Halo game, Halo: Combat Evolved.
The UNSC(Humans), the Covenant (Grunts, Elites, Hunters etc.), and The Flood (parasites)
Elites, or "Sangheili", in Halo are the second highest race or caste in the Covenant, and served as the military leaders before the Great Schism (when the Elites and some followers broke away from the Covenant). They are the tall aliens that seemed to server as leaders of small groups of grunts in the Halo universe as many know it.
