Direwolf

The Direwolves in the Caves were mutated by Herbert’s experiments, turning them feral.  Although they have simple behaviors, their bite can be deadly!
Behaviors:
The Direwolf paces back and forth, and bites at Cally whenever she is within a close range.  In New Game+, the Direwolves will also detect Cally and turn around if she jumps on a platform behind them.
Health: Low

Knife Bandit

Knife Bandits have always been Herbert’s lowest henchmen.  They wear masks to keep their identities a secret, but are usually fodder in the greater battle between Cally and Herbert.
Behaviors:
Knife Bandits move left and right on whatever platform they are on, and start slashing with their blades as soon as Cally comes within a close range.  They will also detect Cally if she is on a platform behind them and turn around to face her.
Health: Low

Bat

The Caves have always housed bats, and it was never a problem until Herbert came along.  Whatever the purpose of his experiments, they turned the bats rabid and now they lie in wait for something to sink their teeth into.
Behaviors:
Bats are always sleeping on the ceiling.  When Cally gets within their detection range, they will wake up and fly at Cally at one of three speeds – slow, medium, or fast.  Bats can fly through walls and will always be flying towards Cally’s position if they are awake.  They have a critical vulnerability to the frost mod, which makes them freeze and smash on the ground.
Health: Low

Smokey

Smokeys (formely known as Pistol Bandits) are engaged in a societal struggle with cigarettes.  Although they will shoot anyone that isn’t on Herbert’s side, it’s good to see that they are now on the nicotine patch.
Behaviors:
Smokeys walk back and forth, and turn if they hit the edge of a platform or a wall.  Every once in a while, they will stop, drop to one knee, and fire two bullets in Cally’s direction (the bullets only travel horizontally).  In the regular game, the minimum time between Smokey’s firing cycle is 3 seconds.  In New Game+, the minimum time between Smokey’s firing cycle is 1.5 seconds.  Smokey bullets can be parried by Cally, and will do a huge amount of damage if they hit an enemy after being parried.

Green Slime

The Green Slimes live under the rule of the Royal House of Carls, and are unpredictable beasts.  Don’t let their cute looks fool you, they have teeth the size of knives.
Behaviors:
The Green Slimes move along the ground and start bouncing randomly.  Every couple of seconds they might change direction/speed.  When this direction change occurs, there is a 60% chance they will move towards Cally.  Slimes bounce proportionally to how far they fall.
Health: Low-Medium

Bee

Bees are the spawn of Queen Shelly, and work in unison to protect the territory around the hive.  The drones aren’t very smart, but their stingers are deadly.  Once a bee sees you, it will never stop chasing you.
Behaviors:
Bees lie dormant until Cally gets within a certain range.  When she does, the bee wakes up and flies towards Cally, avoiding any walls in the process.  Bees are especially susceptible to attacks from the Sword and Spike Gun.
Health: High

Spider

Spiders are the children of Buzz the Terrible Tarantula, and can be found lurking in the Forgotten Forest.  Spiders are known for their ability to leap across great distances, and trap their prey.
Behaviors:
Spiders lie in wait until Cally comes within a certain range.  When she does, they wake up and jump towards Cally.  Spiders rarely move across the ground, but usually jump once or twice, followed by a brief pause on the ground.
Health: Low-Medium

Hulking Bandit

Hulking Bandits are known for their huge size, and low intelligence.  What they lack in smarts, they make up for in firepower, as they wield a deadly Rocket Launcher.
Behaviors:
Hulking Bandits walk left and right, turning around at the edge of a ledge or a wall.  Every few seconds, the Hulking Bandit will flex his arm, and two rockets in quick succession.  The rockets have a wide damage range, so make sure you aren’t standing to close to a Hulking Bandit that is facing you.  Hulking Bandit rockets cannot be parried, and should be avoided at all costs.
Health: High
Mods it is Vulnerable to: Shock, Freeze, Poison, Explosive

Skeleton

No one knows the origin story of the Skeletons that inhabit the Caves. Many have speculated that Herbert resurrected the souls of the Mordecai civilization, but nothing has been proven.
Behaviors:
Skeletons walk left and right, turning at the edge of a platform or a wall.  Every few seconds, the Skeleton will throw a bone projectile directly at Cally, no matter where she is in relation to the thrower.  Skeleton bones can be parried, and will do a great deal of damage if they hit an enemy after being parried.
Health: Very high
Mods it is Vulnerable to: Explosive

Red Slime

Red Slimes are an offshoot of the slime genus.  Red Slimes generally live near lava, and over time have evolved to generate heat themselves.  While a Red Slime might seem easy to fight, they are relentless in the pursuit of their prey, and have an explosive surprise once they are defeated.
Behaviors:
Red Slimes bounce around randomly, bouncing off of any solid surface it hits.  Every few seconds, the Red slime will change direction and speed.  At the time of this direction/speed change, there is an 80% chance the slime will start moving in Cally’s direction.  Once a slime is defeated, it flashes for a couple of seconds, before exploding into a fireball that can damage Cally.
Health: Medium-High
Mods it is Vulnerable to: Freeze, Poison

Turret

Herbert’s new robotic turrets are the result of several prototypes that couldn’t do their job properly.  In the past, Herbert has used Skeleton skulls and magic to control his turrets, but now he uses technology.  
Behaviors:
Turrets lie dormant until Cally comes within their range, at which point the Turret’s siren starts lighting up.  Every few seconds, the Turret will fire a bullet directly at Cally.  If Cally moves to the other side of a Turret, it will turn to face her.  Turret bullets can be parried, and will do a large amount of damage if they hit an enemy after being parried.
Health: Medium
Mods it is Vulnerable to: Shock, Explosive

Balor

Balor’s were long thought of as demons from Irish folklore, until Cally discovered them living in the Caves on her first adventure.  Balors have a short temper, and an explosive fireball attack that causes devastating damage.
Behaviors:
Balors walk left and right, always facing the side that Cally is on.  They will lift their arm and shoot a fireball very frequently.  The Balor’s fireballs cause Cally to lose 2 hearts, making them especially devastating.  Balor fireballs can be parried, however, and will deal massive damage if they hit an enemy after being parried.
Health: Very High
Mods it is Vulnerable to: Freeze

Hopbot

Hopbots are the foot soldiers of Herbert’s robot army, and operate in a simple hunt-to-kill capacity.  Their incredibly dense titanium shells are attached to spring-propelled legs, making Hopbots the ultimate bludgeoning tool.
Behaviors:
Hopbots will wait on the ground for several seconds before jumping, and repeat this behavior.  If Cally is beyond a certain distance threshold, the Hopbot does a high-arcing jump.  If Cally is closer than the distance threshold, the Hopbot does a low, fast-moving jump.
Health: High
Mods it is Vulnerable to: Shock, Explosive

Bomber

Bombers are another member of Herbert’s robot army.  They are generally used to guard wide open areas, carpeting the ground with their deadly bombs. Behaviors:
Bombers fly left and right, turning around when they detect a wall in front of them.  Bombers will drop bombs at randomly chosen intervals, even if they are frozen.
Health: Medium
Mods it is Vulnerable to: Shock, Freeze,  Explosive

Ent

Ents are ancient, dead trees that Herbert possessed with spirits through dark magic.  A mysterious green fire burns within them, and somehow gives them regenerative powers that can keep them alive forever.
Behaviors:
Ents walk back and forth, and will only turn around if they hit a wall, the edge of a platform, or if Cally is standing directly behind them.  If Cally gets too close, they will stop and raise their branches, followed by slamming them down in the direction they are facing.  Ents also regenerate HP constantly, and have no maximum HP threshold.  This means you have to deal with Ents quickly, or risk facing a near-unbeatable monster.
Health: Very High
Mods it is Vulnerable to: Poison, Explosive

Shield Bandit

Shield Bandits are one of Herbert’s higher-ranked minions.  They wield enormous shields that will block any projectiles except flames, and are known for trying to corner opponents between their shield and a wall.
Behaviors:
Shield Bandits walk left and right, turning at the edge of platforms or walls.  If Cally jumps on a ledge behind a Shield Bandit, they will turn to face Cally and walk in her direction.  Shield Bandits can only be damaged from behind, unless you are using the flamethrower which can damage them regardless.  Due to Shield Bandits being able to block anything they are facing, it can be handy to use a rapid-fire weapon on them to combo-chain their stunned state.
Health: Medium-High
Mods it is Vulnerable to: Shock, Freeze, Poison

Circle Bot

Circle Bots are more of a tool than a weapon, and are designed for clearing platforms to make them ready for use by humans.  Instead of using them for this purpose, Herbert has planted them all over the platforms in the Caves, using them to get in Cally’s way and make her journey far more difficult.
Behaviors:
Circle Bots always rotate/move clockwise, circling around any platform they are placed on.
Health: Low-Medium
Mods it is Vulnerable to: Shock, Explosive

Skeleton Warrior

Skeleton Warriors are an upgraded version of the Skeleton enemy that have a Sword and a Shield in addition to throwing bone projectiles.  They will try and hit Cally with a projectile to stun her, then close in and defeat her with their swords.
Behaviors:
Skeleton Warriors walk left and right, and will turn around if Cally jumps on a platform behind them.  Periodically, they will throw bone projectiles directly at Cally.  If they get within close range of Cally, they will start repeatedly slashing with their sword, and if they hit Cally, they will not stop attacking – unlike other enemies.  The Skeleton Warrior’s bone projectile can be parried, and will do massive damage if it hits an enemy after being parried.
Health: Very High
Mods it is Vulnerable to: Explosive

Shield Shooter

Shield Shooters are similar to Shield Bandits, they are higher members of Herbert’s hierarchy of soldiers.  They hold defensive positions and use their shields to block any projectile, except flames.  They also lower their shield momentarily to fire slugs at Cally.
Behaviors:
Shield Shooters don’t move, but will face whichever direction Cally is in.  Periodically, they will shoot a bullet horizontally in Cally’s direction.  Their shields make them invulnerable to projectile attacks, except flames.  They are also momentarily vulnerable when firing their weapon.  Shield Bandit’s bullets can be parried back at them, which almost always causes them to be defeated immediately.
Health: High
Mods it is Vulnerable to: Shock, Poison, Explosive

Merman

Mermen are hideous creatures that inhabit watery areas and have an inane thirst for combat.  The people of Merryfeather believe the Mermen used to be fish, and were mutated by Herbert’s first experiment.
Behaviors:
Mermen pace back and forth and can walk on both land and water.  Periodically, they will throw an explosive trident at Cally.  If they are not facing Cally at the time of throwing, the Merman will turn around to face her and walk towards her.  Mermen tridents are different than most enemy projectiles, in that they will destroy any of Cally’s projectiles that they hit.  The tridents can be parried, however, and will do massive damage if they hit an enemy after being parried.
Health: Very High
Mods it is Vulnerable to: Shock, Poison, Explosive

Robo Warrior

The Robo Warriors are Herbert’s toughest minion, and are created by combining a Hopbot with a mech body.  The Hopbot acts as the control system for the Robo Warrior, and follows Herbert’s orders even if it jeopardizes the Robo Warriors safety.
Behaviors:
Robo Warriors pace left and right, and stop at the edges of platforms or walls.  Periodically, the Robo Warrior will stop and fire two batches of two rockets.  If it is not facing Cally at the time of firing, the Robo Warrior will turn to face her first.  Robo Warrior Rockets cannot be parried, and will take 2 HP off for every time they hit Cally, making them one of the most deadly enemy projectiles in the game.  Also, after defeating a Robo Warrior, its Hopbot control center will remain, and must also be defeated.
