|"These Gates appear as wavy, transparent teleports and act as entrances for heroes. They are a weak spot in your Dungeon so guard them carefully."|
|— Dungeon keeper Gold Manual|
In Dungeon Keeper, the Hero Gate isn't a room as such, it is a magical portal through which Heroes can enter your dungeon. Once certain criteria is fulfilled, Heroes are flung out of the Hero Gate (not dissimilar to how Imps are spawned with the Create Imp spell.) and form a party to storm your dungeon. There is no way to disable these gates, so make sure to defend these weak points with Traps and Doors as well as Guard Posts.

|"The Hero Gate is the entrance through which the hordes of the Good can enter your domain. You would do well to guard it wisely, if you find one."|
|— Dungeon Keeper 2 Manual|
Heroes enter the underworld through this gate in the campaign and in pet dungeons. It can be destroyed when all the 12 surrounding tiles are claimed by player. After it is disabled it will not longer spawn hero parties for the rest of the game.In contrast with Portal and Mercenary Portal it doesn't summon heroes, instead hero parties will spawn from it regardless of the dungeon layout. The amount and level of heroes is defined by each level's script. Some hero gates may throw higher level heroes at the player.
It is important to remember to not to overspend on traps and defenses for hero gates you cannot disable, the hero spawn is often limited and the gate will often stop spawning after a few parties of heroes appeared and thus makes itself out to be a threat. This is however different in each level and for each hero gate. Some begin to spawn heroes after specific conditions are met (for instance a trigger is fired by a player attack).
