A't'trr

&nbsp "We are also here" The A't'trr talking through O'Neil.

The A't'trr are an advanced alien hive mind encountered in the early days of Stargate SG1.

Appearence
The A't'trr are actualy thousands of microscopic creatures impossible to se with the naked eye. Colectively they floress in ultrovilet light; revealing electric blue tendrills wherever they have spred. When feeding they glow.

Abbilities and Technolegy
The A't'trr feed on heat and oxigen. They can withstand extreame tempretures such as direct exposure to a blow torch or an explosion. They claim that an explosion that would destroy the SGC would be enough to allow them to spred across the planet.

Once they reach a large enough number they can express their hive inteligence allowing them to comunicate with other lifeforms. Despite their small size they are an advanced race as event by the remains of the city on their home worls and their Orb.

In the Series
Prior to encountering SG1 the A't'trr discovered that their homeworld was becoming uninhabitble. Unable to save their world they created a cryogenic device called the "Orb" to cryogenically preserve the species. They planned to wait untill another species would come and take the orb through the Stargate to a new home.

The Orb was eventualy discovered by SG1 who took it back to Earth to study. Exposed to the atmoshphere of a living world the Orb soon started to activate panicking the SGC who decident to send it back through the gate. Realising what they intended to do the A't'trr releases sevral spikes from the orb imbeding it into the gate room and trapping O'Neill who was pinned by one of the spikes.
