Quintesson

The Quintessons are an ancient race of bizarre mechanoids, whose history and clandestine machinations are tied together with that of the various Transformer subspecies, along with connections to both Primus and Unicron. They prefer subtle manipulation combined with scheming and advanced technology over brute force; if the above doesn't work, they can fall back to their legions upon legions of deadly Sharkticons and Allicons or their fleets of battle-ready starships. Quintessons themselves have absolutely no fighting abilities whatsoever and are absolute cowards if they have nothing to hide behind. Quintessons are also known by their associated racial slur: squids.

Caste Physiology
Quintessons appear to be mostly - if not entirely - mechanical, although one theory is that they were once organic beings who slowly added more and more cybernetic parts to themselves until they were completely mechanical. However they came to be, though, there are several body styles seen amongst the Quintesson society, heretofore referred to as their 'castes'.

Judges
Judges, also known as the Imperial Magistrates, are the most prominent and infamous caste of Quintesson, as well as the apparent leaders of the race. They are built upon an inverted egg-shaped body which floats upon a beam of energy, with several wiry tentacles for physical manipulation. However, by far their most distinctive physical characteristic would be their five rotating faces. Each face represents a different aspect of the Quintesson, though for four of the five faces, there are conflicting reports as to what each represents. The order of these faces are unique to each judge. While most judges appear to be of about the same size, smaller models such as Sevax and larger models such as the massive Lord Kledji are also known to exist.
