Grimm Overlord (Male Reader x Overlord)

The Ultimate Army

Y/N and Salem were busy taking a lovely stroll through the Land of Darkness. They were trying to find a place where they could summon a large amount of Upper and Mega and maybe even a few Supreme tier Grimm for their army that would be used to conquer the New World

"Here should be good," Salem said when they reached an area where they stood on a cliff above a lake and plain, there were already some low-level Grimm in the area but they would leave when instructed to. A nice feature Y/N discovered about the lake was that it actually had an entrance to the outside world's rivers and oceans, don't ask how but it was probably magic

"Alright, I'll go first" Y/N said while taking out his world tier staff "[ALL SUMMONS TIMES 100] (without staff, so with staff = 1000 of each unit)"

"[SUMMON UPPER TIER GRIMM ANGEL],

[SUMMON UPPER TIER GRIMM DEMON],

[SUMMON UPPER TIER GRIMM TYPHOON BEHEMOTH],

[SUMMON UPPER TIER GRIMM-MOZA],

[SUMMON UPPER TIER GRIMM REX],

[SUMMON GRIMM BLIND-WORM]"

When he was done there were 6000 Upper-tier LVL 300 Grimm, the Grimm Angels, Demons and Typhoon Behemoths were flying in the air below the edge of the cliff, the Grimm-Mozas were in the dark waters of the lake, the G.Rexs stood looking up at them from the ground and the Blind Worms had their heads striking out the ground to 'look' at their gods
