The Urlik Utrek Federation (usually just referred to as the Utrek Federation) is one of the major powers in the galaxy possessing territory that stretches for over hundreds of light years. The Utrek are one of the biggest threats to the Central Powers, and in the past have launched a number of invasions that have only defeated at high cost to the DDS, Dinos and HCS. The Utrek remain a threat though more recently have been in a grinding war of attrition with the mysterious Mantae.
They have used the Porquatians as a proxy in operations against the Central Powers, especially the DDS and later the Zones but both suffered massive losses when the "assistance" promised to them from the Utrek did not arrive, the Porquatians lost their fleet, the Zones lost everything. The Utrek were once allies of the Remedians and Clones though and parts of both factions fleets are still based on Utrek designs.
Its thought now the Utrek do not want to invade the Central Powers since their defeat at DDS and Dino hands in the last war any more. Their attack on the DDS can only be seen as a huge defeat, they lost hundreds of ships yet only really conquered one Remedian planet.
The Utrek was actually two races, who existed in a symbiotic relationship. The majority Ital provided the manpower and the Elnar command. Following a series of military defeats the Ital overthrew the Elnar, though their defeats have continued. The Utrek's resources are vast, a fleet of over 1000 warships and an army of 45 million men. Much of these are used to control parts of their territory which border some of the most fractious areas of the galaxy (as yet barely known to us). The war against the Mantae appears to be one they cannot win, just prevent the Mantae from winning. This should keep them weakened in other areas though they should still be considered a threat.
