Binding of Isaac: Rebirth Wiki

The Gate is a boss that can appear:

Behavior[ | ]

Like Boss Mega Maw ingameMega Maw, The Gate is stationary and will perform the following attacks:

  • Spawns a LeaperLeaper into the air. It can land anywhere in the room while releasing its projectile attack immediately.
    • There is a maximum of 4 Leapers alive at once.
    • The Gate cannot perform other attacks if there are no Leapers alive. As such, it will also always perform this attack first.
  • Shoots a ring of 9 projectiles that can rotate in either direction while expanding outwards.
  • Shoots two rings of 6 projectiles which expand outwards and rotate in opposite directions.
  • Shoots a ring of 11 straight projectiles in all directions.
    • The Gate's projectiles can damage its Leapers.
  • If there are 2-3 Leapers alive, it charges up and fires a Collectible Brimstone iconBrimstone laser that curves to connect to all Leapers that are not off-screen.
    • This kills any Leapers hit.
    • If faced alongside other enemies or bosses, such as in Boss RushBoss Rush, the laser connects to them, damaging them as well.

Champion Versions Needs to be unlocked[ | ]

Notes[ | ]

  • (except in Rebirth) If The Gate is encountered in conjunction with other bosses, which can happen in Greed Mode and Boss RushBoss Rush, the Brimstone laser will also hit the other bosses and enemies it spawns, damaging and possibly even killing them.
  • Using the (in Repentance)Collectible Eraser iconEraser to remove Leapers causes The Gate to be stuck attempting to spawn them infinitely, as it cannot perform other attacks without any Leapers alive.

Trivia[ | ]

    • Despite being a posthumous version of Mega Maw, The Gate physically resembles a giant HostHost.
    • It's also larger than Mega Maw.
  • Upon death, a small Isaac head can be seen poking out of its corpse before it explodes.
    • Two glowing white eyes can be seen in its mouth throughout the fight, which may also be the Isaac head.
