Chimera

Chimeras are Taken entities that appear to be former Fallen Servitors fused with living flesh. They appear in the Dreaming City, Gambit, and The Reckoning.

Overview
Chimeras appear to be horrific amalgamations of Fallen Servitor components and living flesh. In place of the central "eye" of a Servitor is a gaping maw, lined with rows of fangs. The exterior of the creature is covered with numerous translucent tentacles reminiscent of the appearance of other Taken.

It is currently unknown how Chimeras are created, although the existence of Ascendant Primeval Servitors suggest they have existed among the Taken for quite some time.

To finish the campaign Forsaken - you must defeat a chimera named Voice of Riven which has been summoned by Uldren Sov.

Abilities
Chimeras generally possess variations of the same abilities Servitors use, such as an eye blast, melee and flight. They also have two new powers. The first launches a burst of three to four Axion Darts like Taken Centurions, only the Darts are larger. The second has them spawn numerous miniature Taken Blights, either a single one or up to four at a time, that shield the Chimera and makes them immune to damage until the Blights are destroyed.

They do not possess the ability to teleport or buff nearby enemies like regular Servitors, with the exceptions of Inomina in the Blind Well who can teleport, and the Ascendant Primeval Servitor in Gambit whose Blights can make other Primevals immune at the same time as itself.

Trivia

 * The Legendary Emblem Primeval Prime suggests that these Chimeras might have been former Prime Servitors.
 * This would be further supported by Variks' question to Fikrul, if the latter had betrayed Kaliks Prime to the Taken, which went missing during the Reef Wars.
 * The term "Chimera" refers to a beast from Greek mythology, which had the head of a lion, the body of a goat and tail of a serpent. The term is also used in biology, to refer to an organism containing cells with different DNA. Both meanings are relevant in describing the Chimera in Destiny, as it appears to be a monstrous hybrid of multiple different types of being.
 * Chimeras vaguely resemble Cacodemons from the 2016 first-person shooter Doom, both in appearance and abilities.
 * The organic tissue of Chimeras resemble that of the Achlyophage Symbiote; it is unknown whether there is a connection between the two.
 * It is also possible that the flesh may have been former Fallen, that was horrifyingly combined with that Servitor, while being Taken.
