Monsters are creatures in Clicker Heroes that spawn on zones and must be killed in order to progress in the game. Upon defeat, they will drop Gold, which can be used to hire and upgrade heroes.
Each monster has a set amount of HP, or hit points, equal to the amount of damage that must be dealt to kill it. Monsters of the same zone will always have the same amount of HP, and with each zone, the number of HP all monsters have rises.
The formula for monster HP at any zone can be found here.
As the monsters get more HP, their Gold drop will also increase to keep up with the increased cost of the heroes that need to kill the monsters.
The formula for monster Gold drop at any zone can be found here.
Progressing[]
To advance in zones and progress in the game, you have to kill a certain amount of monsters each zone. This number depends on the following factors:
The level (every 500 zones, the number of monsters required goes up by 0.1)
There are two types of zones: regular zones and boss zones. Regular zones require you to kill 10 (plus 0.1 for each 500 zones) monsters in order to unlock the next zone; boss zones only one. To make up for that, monsters on boss zones have more HP than a monster on a regular zone would have, and they have to be defeated within 30 seconds.
Kumawakamaru lowers the number of monsters required to finish a regular zone, up to a -8 reduction. This is not taking into account your level of Borb, unless it is 0.
Regular Monsters/Bosses[]
There are 11 different zone types, each containing a different set of regular monsters. Every zone type lasts 10 levels before it switches to the next one, with the exception of the first 10 zones, which contain 2 zone types instead of 1. Below is a list of which monsters appear on which type of zone.

Special Monsters[]
Treasure Chests[]
Treasure Chest can be found on any non-boss zone. They give 10× the zones's base Gold when killed and that number can be increased further by Mimzee. The base spawn rate of Treasure Chest is 1%, but it can be raised with Dora.
A Relic Ooze may replace any non-boss monster that would have spawned between zone 99 and 2/3rd of your highest zone, once per Ascension and only after your first Ascension. They drop a Relic, equip-able items that provide various bonuses, similar to Ancients.
Relic Ooze A creature only seen a few times. Said to hold the powers of a magical relic.
Special Bosses[]
Primal and Centurion Bosses[]
Starting at level 100, every boss zone has a chance to contain a Primal Boss instead. Primal Bosses are just like regular bosses, although they also give you Hero Souls (the health and Gold stays the same). Just like Gold, Hero Souls scales depending on your zone. Only the first boss on a zone can ever be primal. Once it has been defeated, the next boss that spawns will be a regular one, and will not award Hero Souls again. However, failing to beat a primal boss and returning to the zone will mean that the boss is primal.
In addition, every 100 zones up to zone 1000 a Centurion Boss can be found. The game will treat them as if the zone had a Primal Boss, the only difference being that Centurion Bosses have a 100% spawn rate, whereas Primal Bosses only spawn 25% of the time. Atman can increase this to over 100%, although realistically the percentage cannot surpass 100. PBC (Primal Boss Chance) decreases however which is the reason for Atman being able to do so.
The 10 Centurion Bosses are unique monsters that cannot be found on any other zone. When you defeat these bosses for the first time, you will get an achievement.
Omeet He's just a widdle hamster!
The Green One Thought to be the incarnation of nature itself, he is a force to be reckoned with.
Woodchip, The Rodent Could use with a diet.
Queen of Bloops No mother is happy when her children get killed. A lot.
Doppler, the Robot He sees all that is in the heavens. Some say he can see back before it all began.
Rashon, the Duke Bow down to your lord, RASHON.
The Dark Wizard No one knows why he is here, but he is in your way!
Tako, Head of the Octopi So this is where all of those tentacles were coming from..
Tako Returns He was a robot this entire time!? Or maybe he wanted a rematch..
Lagomorph of Caerbannog It's just a BUNNY! Here I got 'em. Oh, there goes my neck.
Kappa Boss[]
When reaching a boss level, there is a very low chance that instead of the normal boss for that level, it will spawn this "Kappa" boss instead. It is a Turtloid Warlock enemy, but with the twitch.tv "Kappa" emote on its face.
Kappa Gives no bonuses. Scammed!
Monsters from Mr. Mine[]
After patch v2.7.3941 (September 28 2023), 4 monsters from Mr. Mine suspiciously invaded the land of Clicker Heroes and replaced the 4 monsters from Crossy Road. These monsters are Purpa, Astronaut, Rock Monster and Radioactive Butcher. With a small chance of luck, you can encounter them as a boss. In addition, in the map Caverns, you'll also have a chance to encounter the special underground mine map. (Note: This feature is currently available only in Android Version!)
For some reason the monsters didn't make it to the Web version on the game although the underground mine map exists in the game.
Be sure to tap them extra hard and send them back underground where they belong! (But be careful to not break your phone!) - Playsaurus
Purpa A small guy you usually only see in depths below 300.
Astronaut The vastness of space!
Rock Monster He has the eyes of a slime and the teeth of Washington.
Radioactive Butcher An amalgamation of tools and skulls held together by an unknown force.
Removed Monsters[]
Ramicorn A little far from the grazing grounds aren't you?
Immortals[]
Immortals are boss monsters that only appear in Clan raids, and as such, being in a Clan is required for fighting them. They don't take damage from your DPS. Instead you have to click them and/or use Auto Clickers, but the damage from each click only increases when you get primal Hero Souls. Killing them rewards you with Hero Souls.
This guy is the 1/10 dentists that don't recommend toothpaste.
Eyes to meet you!
