Grimm

Intro Alright, let's break down who Grimm is in Hollow Knight in a more casual way Grimm is basically the ringleader of this spooky traveling circus called the Grimm Troupe . He's a major character you meet in the "The Grimm Troupe" DLC, and he's got a pretty important job to do with some fiery rituals . What's His Deal? So, the Grimm Troupe shows up in Dirtmouth after you light the Nightmare Lantern in the Howling Cliffs . Grimm needs you to go around and collect "flame in dream" by beating up his Grimmkin buddies scattered around Hallownest . This makes your Grimmchild charm stronger .   As you keep collecting flames, Grimm will eventually throw down with you in a boss fight . Turns out, all this flame collecting is to keep the Nightmare's Heart going. You get a choice: either finish the ritual by fighting an even tougher version of him called Nightmare King Grimm, or just kick the Troupe out of Hallownest by putting out the Nightmare Lantern . How Does He Look? Grimm has a couple of forms: - Troupe Master Grimm: He's tall and slender, with a cool cloak, a pale face, and those striking red eyes . - Nightmare King Grimm: Think of Troupe Master Grimm, but completely red and even more intimidating .   What's He Like? Even though he's kinda a villain, Grimm is pretty polite and always bows to you . He's super into the whole ritual thing and sees fighting as a dramatic dance . Fun Fact Grimm is heavily inspired by vampires, especially Dracula, and those creepy vampire moths .
