Stomper - an amphibious creature which launches itself up, then comes crushing down. Their attack is similar to Stomp.
Flyer - a birdlike creature with four eyes which resembles Kuro. They hover in the air idly until Ori comes within range, then they quickly bolt towards them.
Slime - an oozing blob of purple, glowing material. When Ori is near a Slime, it will spit out three small droplets that can cause damage on contact, but fall in a predictable pattern and are easy to avoid. Slimes themselves have no other methods of attack/protection, and are unchallenging to defeat. Bash can be used on them, but not on their projectiles.
Spine Slime - small, dark slimes with the characteristic spines. When approached, they fire several small projectiles into the air. The projectiles cannot hit Ori, but they create a hazardous glob when they hit the terrain. These globs can be destroyed with Stomp or Charge Flame; they will also disappear if left for several seconds. Like the Slime, Bash can be used on Spine Slimes, but not on their projectiles.
Dropper Slime - a small dark purple slime that sits attached to a ceiling and drops down when Ori stands under it, exploding and dealing massive damage. They are easy to neutralize if noticed in advance, but can be startling if not. Bash can be used to redirect them, and can be used to detonate barriers.
Ice Slime - a slime with an icy blue appearance. They fire icy projectiles which function similarly to the Spine Slime's. Ice Slimes are chiefly found in the Forlorn Ruins, or around its entrance.
Flame Slime - a slime resembling a glob of lava. They fire magma projectiles which funtion similarly to the Spine Slime's. Fire Slimes are chiefly found within Mount Horu, or in its entrance's vicinity.
Split Slime - a large purple slime that splits into two smaller slimes upon death, each of which likewise splits into two even smaller slimes, which once again split into two tiny slimes. Split Flame and Ultra Split Flame abilities are very effective against them.
Spitter - a toad-like creature that spits large red projectiles at Ori. Both the Spitter and its projectiles are bashable, and can be redirected.
Green Spitter - a more powerful variant of the Spitter. They fire more quickly, and their shots have a longer range and higher damage. Both the Green Spitter and its projectiles are bashable, and can be redirected.
Spider - they sit attached to a ceiling by a line of silk and shoot one or three purple projectiles at Ori when in range.
Rammer - resembling an armored rhino, Rammers charge rapidly towards Ori when approached. Their armor protects them from damage, but it can be removed by Charge Flame or Stomp.
Kamikaze - when Ori is in range, they will roll up into a ball, then try to ram into Ori. They explode when they hit Ori, an enemy, or a wall; the explosion causes massive damage and can destroy certain walls. Bash can be used to redirect them. Most Kamikazes will respawn shortly after exploding.
Fish - found in water, fish charge at Ori when approached. Unlike Flyers and Rammers, Ori cannot dodge their assault and needs to kill them quickly, escape the water or use Bash timely to push them off. They usually can be easily neutralized from distance, but for players without the Water Breath ability they pose an additional threat in the already stressful underwater environments.
Mortar - a serpentine creature who lives in holes in the ground. They will stay inside these holes until Ori comes near, and then they will pop out. If Ori comes close to a Mortar, it will go back into its hole; otherwise it will spit a projectile from its mouth in attempt to hurt Ori. Mortars' shots are highly accurate, and can often be Bashed to allow Ori to reach high places.
Flame Shooter - a glowing entity surrounded by floating rocks. They shoot powerful projectiles which fly in a straight line toward Ori. The only way to destroy a Flame Shooter is by redirecting its projectile back at it using Bash.
Red Flame Laser Shooter - similar to the Flame Shooter, except they alternate between a laser attack and a flame projectile. The laser follows Ori for a short time, instantly killing anything it hits. Like the Flame Shooter, they can only be destroyed by a redirected projectile.
