Supreme Intelligence

The Supreme Intelligence was the monotheistic God worshipped by the Kree, and with the expansion of the Kree Empire Humans and members of Third races joined in Supreme Intelligence worship.

The organized priesthood of the Supreme Intelligence was important because they controlled the government of the Kree Empire (there was a Prime Minister to serve as a secular political leader, but even he was appointed or replaced by the priests of the Supreme Intelligence).

Moreover, many priests of the Supreme Intelligence (but not all) exercised supernatural powers of the Living Force, with an equal emphasis on the Light Side and the Dark Side. In time, the Supreme Intelligence itself was considered identical with the Living Force.

As Kree Empire territory was conquered by the rising Shi'ar Empire, worship of the Supreme Intelligence was still tolerated but many priests of that deity  who exercised Living Force abilities were drafted into the Imperial Inqiusitorius. The same policy continues today under the Intergalactic Empire.

There has also been a growing syncretic religion that identifies the Supreme Intelligence, the Living Force, and the Shi'ar male deity K'ythri as three aspects of the same God.
