Grigorius the Grigori exists to prevent anyone wishing for the Hinnom national summons, who are also called Grigori. Because Wish gives you the first creature of that wished-for type that it finds, and Grigorius the Grigori is unit number 1, anyone wishing for a Grigori will get Grigorius instead of the ultra-buff angel-demon game-breaker he thought he'd get.

There's a rare, unrelated bug that resets a commander's unit type to unit type 1. This used to be an orange-shielded (i.e. old graphics from an earlier version) Legionnaire or Standard Bearer of Pythium. Grigorious the Grigori's description refers to him appearing and disappearing at his choice, so now this old bug has become more confusing.
