Normal Enemies
Stone Grimace
About The Enemy
A Stone Grimace is an invincible stationary statue with the shape of a head with a wide-open mouth and hollow eyes. Stone Grimaces will sporadically spit a Red bullet in Isaac's direction until the room is cleared by killing regular enemies, or by pressing Pressure Plates. When the room is cleared, the Stone Grimace closes its eyes and mouth.
Why I Dislike Them
I dislike this enemy for the fact they are invincible and you have no real way to counter or deal with them beside clearing the room
Host
About The Enemy
Hosts are immobile skulls. When lowered down, which is their normal state, they are invincible to every source of damage except status effects such as poison, burning, being knocked into a wall by Hemoptysis, or Knockout Drops' knockback. Occasionally, they will pop up and shoot three spread shots towards Isaac, revealing a fleshy stem that can be damaged. Attacking a Host while it is lowered will increase the delay before it pops up: if it takes what would be a large amount of damage at once they will grimace.
Why I Dislike Them
I dislike this enemy for the fact they are allowed to stay down as long as the would like, causing rooms to drag on for way longer then they shouldNeedle
About The Enemy
They lunge towards Isaac in an attempt to deal contact damage. Before they lunge, they are characterized by a small lump in the ground. Unlike Pin, they do not move underground relative to where they land. Instead, they teleport to a spot near Isaac before lunging. They can leap over pits and obstacles to reach Isaac if he has flight.
Why I Dislike Them
I Dislike this enemy for the fact there is no indicator that they are in the room until they attack, this causes the player to get hit by them alot because they are unaware of them being in the room
Bosses
Bumbino
About The Enemy
Bumbino slowly moves towards Isaac and can perform the following attacks: Swipes forward to clear a path to Isaac if Bumbino is obstructed by obstacles while chasing him. Performs two swipes, one in Isaac's direction, followed by another swipe in the opposite direction; these swipes can break obstacles. Then slams the ground, releasing 8 rock projectiles in all directions as well as 4 rock waves diagonally. If Bumbino hits a wall or a pit with a swipe he is momentarily stunned, interrupting this attack and causing rock projectiles to fall from the ceiling. His swipe attack will also deflect incoming projectiles. Charges in Isaac's direction when vertically aligned with him and a wall, breaking all obstacles caught in his path. Bumbino will become stunned upon impacting the wall, launching a cluster of rock projectiles in the opposite direction and causes rock projectiles to fall from the ceiling. If Isaac is close to the impact, he is pushed away. Launches a Butt Bombs Bomb in Isaac's direction.
Why I Dislike Them
I dislike this boss for the fact that their arena is so cramped and their attacks are so big, it causes you to get hit by most of them. This causes an unfun boss fight.
Great Gideon
About The Enemy
Great Gideon is always fought in a vertical double-size room and has no health in a traditional sense. Instead, Isaac must battle 6 waves of monsters to beat him. Each wave begins once all enemies from the previous wave have been defeated. He also will fire projectiles during waves.
Why I Dislike Them
I dislike this enemy for the fact there is so much to keep track of.
