GenTubeOur free Hollow Knight OC maker designs your bug knight for Hallownest in seconds — white mask, void eyes, nail and cloak.

These are real vessels and bug knights creators dreamed up on GenTube. Picture your OC standing beside the Knight, Hornet, Quirrel or Grimm: a hand-drawn gothic mask with black void eyes, a worn cloak, and a trusty nail. The look is muted and desaturated, all the dark beauty of Hallownest. Build your own Hollow Knight OC for free, no limits.
The vessels and bug knights of Hallownest, made by the GenTube community.







A Hollow Knight OC is your own original character set in Hallownest, usually a vessel or bug knight with a pale mask, black void eyes, a cloak, and a nail. Fans give them horns, unique mask shapes, and their own backstory in the kingdom.
Both. You can recreate canon faces like the Knight, Hornet, Quirrel or Grimm, or invent a brand new vessel of your own. Describe the mask, horns, cloak and nail you want and generate as many versions as you like.
Ask for hand-drawn dark gothic art, a muted desaturated palette, a white or pale mask with black void eyes, and the underground kingdom of Hallownest in the background. Add horns, a tattered cloak and a nail to lock in the vessel look.
Yes. Making Hollow Knight OCs on GenTube is free with no caps. Generate, tweak and remix as many bug knights as you want, no limits.
Yes. Every OC you make can be shared, and you can remix other creators vessels into your own designs. It is a whole community building out Hallownest together.
The classic kit is a nail (the games sword) plus a cloak and a carved mask. From there add charms, horns, glowing void or soul effects, and a color story that stays muted and gothic to match the world.
