Bullat

Bullats are small enemies that simply launch themselves at the player, dying in the process. They possess flight, allowing them to back off into unreachable and long distances to perform their attacks from afar. Because of their low HP, they can usually be killed in one blow by any attack, even dodge rolling.

Shotgat
Shotgats are shotgun shell variants of the normal Bullat. They behave like regular Bullats, but fire two projectiles in a V shape. Like Shroomers, these attacks can be evaded by standing still.

Grenat
Grenats behave like regular Bullats, but explode upon death or upon hitting an obstacle.

Spirat
Spirats behave like regular Bullats, but can teleport away before hitting a wall and re-launch themselves, predicting the player's movements each time. If the player is close to a wall or behind cover, they may simply hit a wall and disappear without teleporting.

King Bullat
King Bullats fly in place, frequently firing bouncing bullets in all directions. Upon death, they spawn approximately 4 Bullats and Shotgats.

Spawned Bullat's jam chance is separate from their parents, with each Bullat having an independent jam chance.

Trivia

 * It's possible that the reason King Bullats shoot bouncing bullets is based on how real Bats use echolocation.
