 THIS THE STAR TREK NOVUS PAGE ON THE Ϙ USING CANON AND NON-CANON DETAIL  The Ϙ were an omnipotent, godlike, immortal extra-dimensional species which originated from the Ϙ Continuum.

The Ϙ were incomprehensible to the standard humanoid brain, needed to "stretch the boundaries" of their continuum to compensate. Although the Crataxian brain was able to process and undergo massive amounts of data, thus being able to see the "unseen".

There were 8 known Q as of the 25th century, all collectively notorious in any perceivable way to Starfleet. The 8th was not Amanda Rogers but one meet by the crew of the Inventum.

The most notorious, Q, was nicknamed Q-Loki in 2432 (last appearance ca. 2470s) for his deceitful and obnoxious before whenever met by Starfleet captains.

Starfleet deemed it as incomprehensible as there natural form for why such a intellectual and seemingly sound species wound want to lay such peril and annoyance upon species. Although the generally accepted theory was they were just...show-offs.
