There are a lot of heroes in Kingdom Rush and their performance varies a lot when using them, so it can be tough to decide which ones to invest in and also which ones to run.
For that reason I have written this tier list to give you not just a plain list or overview, also give you insights about every heroās performance in Kingdom Rush in the current state to help you decide.
The Best Heroes in Kingdom Rush
Without wasting more time, letās jump right into the tier listā¦
UNBALANCED
Why is there an unbalanced tier? Well, there are heroes that are straight broken in Kingdom Rush and I donāt want to rank them in the highest tier to recommend investing in them just to see them getting a rework or nerf soon. So, if you have them or want to build them on your own risk, you have overpowered heroes to run but be aware that this can change quickly.

Eiskalt is straight-up unbalanced. Thereās barely anything to like about this character other than the fact that heās just not in working condition at all in the game. The only thing he does is freeze and that does so much damage it makes the game unfair to play.

Beresad is, just like all the other dragons in Kingdom Rush overpowered in a broken way, and his speed is simply unmatched in all of Kingdom Rush. His attacks are so fast, and his HP is so high that itās just unbearable to have such an unbalanced character in Kingdom Rush.

Murglun is just as broken as Beresad, and heās almost the same as Beresad as well. Too fast for the game to be fair, too much HP and way too much damage. Not to mention, Murglun also has an instant kill attack and a lava attack for crowd control. Itās just too much money, it makes the game completely pay to win.

Phoenix is honestly almost as bad as the dragons, too loud and the player barely gets to play the game due to how unbalanced this character is. Itās not unfair levels of unbalanced, but thereās still a broken nature to it.

The lord of death and disease, Bonehart is a fun character to have but heās also suffering from the same problems as the rest of the dragons. The unbalanced aspect of this character, and the fact that it costs money makes him pay to win. Thereās not much you can do about it when you are up against a Bonehart.

Faustus is just as broken as the rest of the dragons mentioned here. I do have to say that this is one of the weakest ones on the team, but heās still too strong to be considered balanced.

Blazing Death and Feast make Ashbite a pain to go against, but also an easy target. However, that wonāt matter at all because he simply has so much HP you canāt do anything against it.
S+ Tier
Mobing away from the tier of heroes that are straight unbalanced to the ones that are absolutely strong and ones that I can recommend without any limitation. These heroes here are so much stronger than the other ones (except the broken ones)

Dante not only has all useful abilities, he by far has some of the best damage and speed in the game overall. Heās a super powerful hero with a ton of versatility in terms of gameplay, and can be used in almost every situation!

Super strong and super powerful, Captain Blackthorne has the power to give gold literally. Heās got a great main attack, and his abilities are almost all useful. Heās got amazing crowd control as well as single target damage too, plus his ultimate is awesome. Heās easily a balanced, yet powerful, hero!

While he may not be great against magic-resistant enemies, Mortemis can literally tear apart anything you put in front of him. Heās very tanky, very fast and somehow has extremely useful abilities that can keep you fighting by lowering enemiesā resistances. He can even reanimate dead enemies as zombies, his ground units can damage flying enemies and stun them too! Heās fantastic.

Jack OāLantern has the same kind of benefits as Mortemis. Heās strong, not too tanky, but fast and light-footed enough with some of the best abilities in Kingdom Rush.

Not only is Bruxa a VERY high single damage character that relies heavily on her fast movement speed and ranged AoE attacks. Not only can she deal a ton of damage to crowds, but she can deal a massive amount of damage to single targets. Moreover, sheās so fast itās impossible to catch her!
S Tier
The heroes in this tier are also really strong and very powerful, but compared to the ones in the S+ tier a little less powerful, thatās why they are in this tier.

Art-design-wise; Elora Wintersong is probably one of the coolest characters in Kingdom Rush. Moreover, she has good damage, decent attack speed and great abilities. She can also deal a ton of damage using her main attack, so thatās really useful in certain situations!

Magnus Spellbane has got super strong abilities; he can teleport anywhere he wants on the map, and he can clone himself. His damage is fantastic too and he can do devastating amounts in short bursts of time. Heās a glass cannon, but heās pretty darn good.

King Denas is one of those underrated characters that you need on your team. He can extend the range of the towers; his attack speed is super-fast and he has an artillery barrage for support purposes. Heās just an all-around GOOD character!

Asra can break physical armor on each main attack after being upgraded. Not to mention, her spider bite ability can simply dismantle enemies by poisoning and dealing damage over time. Sheās fantastically balanced, and well designed.

Kahz is criminally underrated, he is a living breathing wrecking ball. He has insane damage capabilities, and he can make your barracks overpowered for a short span of time. His teleportation gives him so much more room to maneuver around.
A Tier
Heroes in this tier are still strong and very viable, just compared to the upper tiers not that strong but thereās no reason not to have and use them.

Ingvar Bearclaw has got to be one of the most well-balanced characters in the game. Heās great at crowd control, and despite his slow movement and attack speed, he can summon support units to aid him in combat and he has chance to become invulnerable for a decent amount of time on the field!

Sir Gerald Lightseeker, the Paladin, will support barracks as good as anyone else, heāll tank bosses and heāll deal damage whenever you need it! Some characters might do his job better than him, but heās still lovable!

Vezānan goes to the A Tier instead of the S Tier simply because heās a bit lacking in power and heās hard to use as a hero. Other than that, heās simply King Denas but with a magical affinity rather than purely physical damage.

Wilbur will always struggle against high HP enemies, but if the enemy has a medium or lower HP, heāll destroy them. Heās got decent attack speed and single target DPS maneuvers, heās got it good.

Grawlās got 900 HP at max level, and heās got decent crowd control abilities against small units. He is meant for tanking, and he tanks better than almost every other character.

Dierdre requires an acute mechanical skill at microing, thereās no other way around it. Sheās going to support your barrack troops better than mostly anyone else, but you have to micro otherwise she wonāt survive much.

Saitam can make enemies receive extra damage for a short burst of time, and he has some of the best abilities in the game. However, he has limited crowd control, but heās well balanced enough that it doesnāt become too detrimental.

Alric is essentially just like Karkinos, he has a huge survivability and a ton of damage. However, he can summon up to three units which makes him SUPER strong. Heās basically as strong as Gerald, but a bit better overall in terms of usability.

NivusĀ can teleport, he can crowd control, he can insta-kill, he can do everything! The grand wizardās only detriment is that he has an HP cap and is a glass cannon. However, if youāre moderately good at the game, heāll win you games!
B Tier
The B Tier is basically a niche tier, that means that heroes here are either good for specific things where they can be as good as the ones in the upper tier, but overall they are not that versatile.

Mirage has the chance for an insta-kill, not to mention, she has some very decent abilities that also increase her chances to kill. She could have been a higher tier but she struggles against a lot of enemies, which makes her a tad weaker.

Karkinos can become invulnerable for a short burst of time when heās below 40 HP. This makes him one of the best characters to have during Endless mode, especially when combined with his high damage. Heās not too powerful in terms of tankiness or abilities, but he can survive quite well on his own.

If you donāt put Veruk up against armored enemies, he will dominate. This walking tank can take control of the battlefield within an instant and turn the tide in your favor. Not to mention, heās free!

Doom Tank SG-11 is very much like Veruk, but heās a bit more on the overpowered side when it comes to his fantastic abilities and expendables. However, heās very vulnerable to certain types of enemies, which and theyāre resistant to his attacks which makes him weaker in general.

Jigou is just Grawl but with a different skin. Theyāre essentially the same character, role and class included, but they have different elements. Jigou is just unoriginal and wasnāt necessary, but heās still a good character overall.

DuraxĀ is only for those who like his abilities, especially since theyāre very cool and he can clone himself too. He might deal a TON of damage but heās a bit confusing to use if youāre not sure how to use macros.

Arivan barely deals any damage at all through his main attack, but his abilities are what carry him through. His abilities are absolutely busted at times, and if youāre good at microing and know how to play him, he can be quite great for you!

Malik Hammerfury has pretty decent abilities, and heās very balanced. Not to mention, his role is clear to play but he doesnāt do it too well, heās one of the better supports class characters in the game, nonetheless.

Bolverk is the same as Malik in most ways. He has decent abilities, heās well-balanced, he has a very cool design and heās one of the better secondary heroes in the game.

Eridan, the Ranger, is quite useful, with all of his abilities having some sort of situational purpose. However, heās a bit too situational to be anything more than B tier. Overall though, heās a decent hero.

Oni is the coolest character in the game by far. Heās not the most useful one though! He has a decent damage, all his abilities are decent too and heās tanky. However, he is VERY vulnerable to ranged units which can be detrimental in almost every level, he simply dies too easily.

Bravebark, the Ent Lord, is a great character. Heās full of personality and has a decent support system and survivability. If only his damage was better, heād be up in A Tier at least.
C Tier
Heroes in this tier can have very specific uses but have an overall weakness or are simply overall weaker than the heroes ranked above and should not be any long-term choice.

Alleria Swiftwind is still better than mostly anyone lower on this list. She has fast attacks that deal light damage, sheās slow in every other way but her light attacks though. She does level up very fast and sheās a free character, being one of the original Kingdom Rush characters.

Prince Denas is a bit weaker than King Denas of course, but the Prince still has Sworn Defenders to stall enemy units and can deal moderately decent physical damage. Heās got some good things!

Ignus is fiery cool, but thereās an issue with him. Heās insanely overpowered, which makes him a bit boring to play and too bland to like. Despite the fact that his abilities are really good, his main attack is awesome and heās fast enough while dealing a ton of damage.

Lilith can deal a whopping 1600 damage when her ultimate ability is on fleek. However, most of the time youāre unsure whether the character will work for you or not. Itās a gamble picking Lilith, sheās either too strong or not at all.

Lucrezia is only good in one particular level, with decent crowd control abilities and a tanky HP
to help her out, she is at least a decent character.

Margosa can be useful when focusing on one target at a time. However, sheās not too tanky and can be taken out quite quickly. Her ultimate though, can be regenerated almost the whole game so that helps!

TraminĀ has his uses. Somewhat of an underrated character because he has a decent stun, as well as splash damage with his main attacks despite the low area of effect.

Regāson is great against Twilight Golems and becoming a human shield. Thatās about the best you can do with RegāSon, but he can keep benefitting off of enemies dying!

Shaātra is a decently balanced character, Shaātra can be good in most situations. However, heās simply too weak to deal any extended damage, and his abilities donāt really help much in most situations. His tankiness can help win you battles though!
D Tier

Hacksaw comes with a guaranteed insta-kill if you micro well. He is super slow though, and he doesnāt do a lot of damage.

Kutsao is a fast attacker that isnāt completely useless. Though as far as attacking fast goes, heās not very fast nor does he do a lot of damage. Heās supposed to be a high-damage character, but heās okay at best.

Xin, the diabolical Panda, has almost the same play style as Cronan. He does deal enough damage when levelled up, so that makes him better than Cronan in every way.

The Black Corsair hasĀ got limited range, limited usefulness, and heās not strong enough if weāre being honest. He struggles against Blood Shells, but he deals decent damage to everyone else. Heās not completely useless, but heās limited to say the least.

Bruce is the definition of an average character. His abilities are mediocre at best, his damage is decent but his speed is slow. He does not make a lasting impression.

JunāPai is not a great support character at all, heās wonky and his role isnāt clear for players. In fact, most of the time JunāPai functions more like a DPS, but with poor damage instead. Heās not horrible at support, but he could be so much better.
F Tier

Rurin Longbeard simply has one useful ability, and thereās nothing else in his arsenal of any use whatsoever.

Cronan barely deals any damage! You can level Cronan up to the maximum you want, but heāll only dish out the most minimal damage he can!

You cannot even tell what Razz and Ragsā role is simply because he gets outclassed in every way. Thereās nothing to like about this character, but his voice lines are there for you to hate on!

Catha is bland, her abilities are not only boring but they barely do anything. She has terrible damage, but she can stall enemies and thatās her only use.

Olochās ultimate ability literally doesnāt do any damage, thereās nothing much left to say but that.

Lynn is a confusing character. The people that play her can play her well, but thereās no clear way to learn her, sheās hard to level up and her abilities are simply underpowered.

Thor is the one character I hoped would be good, but heās terrible in almost every way. Heās terrible at crowd control which his main abilities are meant to be used for, and heās got little damage, slow speed and heās simply bad.

If Dwarves are supposed to be OP in Kingdom Rush, Bolin Farslayer is literally the opposite of that known fact. He literally uses a gun instead of an explosive weapon, and deals minimal damage, and has no good abilities.

Dianyun can attack while moving, and he moves quite slowly but he attacks for a ton of HP. This makes him a weak character that costs a lot for not much reason. He is plainly unfun.
Conclusion
So, thatās the full tier list as I see it in the current state of Kingdom Rush and I hope itās helpful for you and give you some insights to plan your hero choices. If you have questions or think I made a mistake, please drop a comment below and Iām happy to reply.

Iām gonna be blunt here: As a Kingdom Rush Playerā¦..this is the shitiest list i have ever seen, im assuming you never played kingdom rush at all and simply took one look at the characters and went from there, because this is the ONLY way you made this excuse of a list
Hi. I understand that I left a comment quite late, but I will write anyway. I think you underestimated Bruce very much. The Beam has a huge damage. He ranks 3rd in traffic police in the 3rd part of kingdom rush. He has the most health out of 3 parts. He has bleeding and a bite that does a lot of damage. Also very understated the Tank. The tank has a huge urons (the largest in the entire history of kingdom rush) He hits very slowly, but still he is insanely strong. In addition , his abilities cause huge damage and he is invulnerable to enemies who do not have a long ā range attack . I can notice many more nuances of this review of heroes. But to be honest , I ām too lazy + I donāt have time . But in general, the review is cool. I hope you will answer.
