Archon Amar

He will gnash his fang-blade, filling the air with deadly coils of flame. Survive the flame, and you might see frenzy. A relentless fury of slashes. Only the greatest of force will subdue him in this. Should he howl, the pack will appear. Mirrors of himself, meant to confuse. Only the true eye can distinguish the alpha among them. Archon Amar is one of Erra's Archons, amalgams of Sentient and Warframe. His head is that of a wolf with the body of a Rhino Prime.
Can't talk.

Amar the Wolf was once a Sentient Beast, which were Sentients created by Praghasa and Hunhow to serve as the peacekeepers of Tau. After fighting and dying in the Old War, Amar and the other Beasts were revived by Erra during the New War as Archons; hybrid abominations of Sentient and Warframe.
On Tau, Amar was created in the image of the wolf, a tribute to ancient Earth and its long extinct ecosystems. There he roamed, without any prey to hunt. He was also the one who taught Natah how to utilize her powers of mimicry and deception.
As an Archon, Amar is now the main assassin of Pazuul, hunting down any heathens that refuse to submit to Narmer. He dreams of being a lord of the wilderness again, instead of what he is now.

All the fakes do not wield weapons, and the real Amar can be detected using Target Radar. Attacking the real Amar will immediately dispel all clones and cancel its regeneration.
In Archon Hunts, the clones produce a shockwave that inflicts knockdown, and the real Amar gains an extremely small layer of Overguard. Depleting his protection will cancel the ability.
Amar becomes immune to damage, summoning Sentient reinforcements which must be killed to remove its invulnerability.
Amar enjoys relying on melee attacks and getting up close and personal. The main threat is Amar's "pack" of clones and hiding among them while healin.
