Gúta

The Gúta, pronounced "Gueta", is a gigantic troll-like species found on the planet Reach. It is known to be hostile, though its level of tolerance towards humanity is not yet known. It is believed to be an enemy towards SPARTANs because when aimed at with the reticle, the reticle turns red. It is also believed to be hostile to Covenant as well.

Description
The Gúta is the largest terrestrial lifeform discovered on Reach. Severe aggression is rare, outside of rutting males or females with young. Even so, they are extremely dangerous animals. Its affiliation is that of Natural Fauna.

Trivia

 * The Gúta bears a passing resemblance to the cut Blind Wolf from pre-Xbox builds of Halo: Combat Evolved and a very slight resemblance to the Rancor of Star Wars.
 * The Gúta is seemingly named after the Guta, a fearsome demon from Hungarian mythology, as many of Reach's early settlers were of Hungarian descent.
 * In the mission Nightfall, Covenant troops fighting several Gúta will be encountered.
