[Star Wars] Who and what are Gray Jedi?

Why are they not as popular as Sith and Normal Jedi? How many are there? And wouldn't they be more considered antiheroes like bounty hunters?

"Grey Jedi" are force-users who have rejected the discipline of the Jedi Order, but also the teachings of the Sith. They are usually Dark, but claim to have found a "balance" between the two. The idea is that they are neither Dark nor Light, but in-between - "Grey", get it?

Many have suggested that prominent Jedi Knights actually used the Dark Side to aid them in battle, and that they could draw on the strength of both Dark and Light to become greater than either; but there is no evidence to support this legend. It was almost certainly invented by the Sith to ensnare the weak-minded.

Darth Sidious pretended to be such a Gray Jedi before revealing his Sith nature to the young Anakin Skywalker. Anakin mistakenly believed that he would, as Chosen One, "balance" the two "sides" of the Force.

In truth, however, there is only the Force, and the disturbances strong emotions cause. The Jedi way is balance and peace; the Dark Side is imbalance and turbulence. By destroying the Sith active at the time, Vader restored that balance.

[OOC, they were a piece of nonsense introduced by EU writers who had misunderstood the lore. Several Jedi, including Luke and Qui-Gon Jinn IIRC, were retconned into being "Grey Jedi". They are now thankfully erased, eliminating the contradictions and issues they created.]
