Great Gideon is a boss that can be encountered in the Mines and the Ashpit. He is the boss version of the Stone Grimaces. He is always fought in a vertical double-size room.

Behavior

Great Gideon has no health. Instead, Isaac must battle 6 waves of monsters to beat him, similarly to Greed Mode waves. He uses the following attacks during these waves;

• Creates a vacuum that affects the whole room, pulling in Isaac and all monsters. It also pulls in rock projectiles that can hurt Isaac.
• Spits 5 red tears in a cone shape at Isaac. The center one is a bigger projectile that splits into 8 projectiles in a radial burst when it lands or hits something.
• Spits large flame tears down the center of the arena that have the chance to leave fires behind.
• After the beginning of the 4th wave, Great Gideon charges up and releases a rock wave down the center of the room, breaking parts of the floor and leaving gaps.
  • There will always be gaps between the holes left by this attack as to not completely trap Isaac on either end of the room.
  • If Isaac has flight then there will be no gaps between the holes except for a single one at the bottom end of the room.

After Isaac defeats all 6 waves of monsters, Great Gideon will deactivate, just like a regular Grimace.

Monsters

Bouncer	822.0	Wanders around the room, avoiding Isaac. If Isaac stays close to one for long enough, it inflates and starts chasing him, gaining a chance to deflect shots and causing it to explode into lingering blood shots on death.

Notes

• If Chaos Card is used on him, Great Gideon will be defeated instantly. It also opens a unique Crawl Space underneath him containing several items and chests.
• Great Gideon is one of the two bosses that have a unique health bar, the other one being Dogma.

Trivia

• Great Gideon's name likely comes from Gideon, an Old Testament prophet and military leader known for winning a decisive battle against an overwhelming Midianite army with only an army of 300 Israelites

Bugs

Bug!	Spawning Great Gideon with the debug console will spawn him with a normal boss healthbar instead of a "waves" mechanic. Attempting to attack him will result in a game crash.
