Meta-Tier Characters
The Meta tier represents the absolute pinnacle of power. These units dominate the game in every aspect, possessing unparalleled strength and game-breaking abilities that make them indispensable for clearing the toughest content.
| Character | Detailed Analysis / Pros & Cons |
| Dark Wing | Analysis: A premier hill-based DPS unit, Dark Wing is celebrated for his incredible range and devastating damage output. His ability to attack both ground and air units from a safe distance makes him a cornerstone for any Infinite mode strategy. His high cost is a small price to pay for his map-wide influence. |
| Michishibo | Analysis: Michishibo is the epitome of a late-game powerhouse. He applies a potent bleed effect and, once ascended, possesses the highest one-shot damage potential in the game. He can single-handedly eliminate the strongest of bosses, making him an ultimate prize for dedicated players. |
| Etri | Analysis: Etri is a perfect hybrid of damage and utility. His attacks not only inflict massive damage but also freeze enemies in their tracks. This crowd control is invaluable in all game modes, allowing your other DPS units to attack without fear of being overwhelmed. |
| Super God Koku | Analysis: As a hill unit, Super God Koku reigns supreme with fantastic range and truly insane DPS. He is a meta-defining character whose raw power can clear waves of even the most resilient enemies with ease, though his final upgrades require a significant investment. |
| Jin Sung | Analysis: Considered the best ground unit, Jin Sung combines high personal DPS with the unique ability to summon his powerful companion, Igris. This essentially gives you two powerful units in one slot, overwhelming enemies with relentless attacks. He is a must-have for ground-based strategies. |
| Slayer Mage | Analysis: Slayer Mage is a master of wave clearing. Her wide AoE attacks and amazing range allow her to damage huge groups of enemies simultaneously. This makes her a meta-defining unit for Infinite mode, where enemy density becomes a major challenge. Her only minor drawback is a slightly slower attack speed. |
| Venus | Analysis: Venus is a relentless damage dealer, characterized by her insane range and incredibly fast attack speed. She can lock onto enemies from afar and shred their health before they even get close. Her high cost is justified by her consistent and overwhelming DPS on ground paths. |
| Onwin | Analysis: Onwin is the ultimate support unit. He provides a substantial damage buff to all nearby allies, dramatically increasing your team’s overall DPS. He is cheap to deploy and his own summons add extra damage, making him a fundamental part of almost every top-tier team composition. |
| Super Borul | Analysis: Super Borul is another meta unit for Infinite mode, thanks to a powerful passive ability that shines in longer games. This is complemented by his already amazing DPS and range, making him a fantastic all-around hill unit that can carry teams to victory. |
| Blackstache | Analysis: Blackstache is the premier slowing support in the game. His ability to drastically reduce enemy movement speed over a massive area gives you complete control of the battlefield. While his personal damage is low, his utility is unmatched and can trivialize difficult waves. |
| Zaruto (Beast Cloak) | Analysis: This version of Zaruto finds his place in the meta due to his excellent balance of stats. He has a fast attack speed (SPA) and great range, making him a highly reliable and consistent source of damage, even if his peak DPS isn’t the absolute highest. |
S-Tier Characters
S-Tier units are exceptionally powerful and can easily be the star of any team. They are just a step below the Meta tier, often with a minor niche or trade-off, but are still considered elite.
| Character | Detailed Analysis / Pros & Cons |
| Zorro | Analysis: Zorro is a powerful hill unit whose strength lies in his upgraded range and solid AoE DPS. He can slash through groups of enemies effectively, though his slower attack speed and high placement cost are points to consider. |
| Yuni | Analysis: Yuni is the ultimate boss killer. Her single-target DPS is astronomical, thanks to an extremely fast attack speed. She can melt the health bars of the toughest enemies in seconds. Her main weakness is a short range, requiring careful placement. |
| Water Goddess | Analysis: A unit with amazing damage potential and excellent range. Water Goddess is a strong and reliable ground DPS for most game modes, though she can be relatively expensive to upgrade fully. |
| Whitestache | Analysis: Whitestache is a great shield-breaker due to his multi-hit attacks. He has decent DPS and range with a high placement limit for a 5-star, making him great for overwhelming enemies, though he’s less effective against single, high-health bosses. |
| Xero | Analysis: Xero is a pure support unit whose value comes from his powerful buffs to nearby allies. He provides no damage himself but can elevate the DPS of your entire team to new heights, making him a meta support choice. His cost is his main drawback. |
| King Kaoe | Analysis: King Kaoe offers one of the strongest damage buffs in the game (75%), but with a major risk: he destroys your base’s shield. He is a high-risk, high-reward unit for players who are confident in their defenses. |
| The Strongest One | Analysis: An exceptional anti-boss unit, The Strongest One combines amazing range, high DPS, and a burn effect that deals damage over time. He is a top-tier hill unit, held back only by his extremely expensive upgrade path. |
| Airren | Analysis: Airren is a versatile unit who can switch between being a standard DPS and a summoner, providing high full AoE damage. This flexibility is powerful but comes at the cost of being extremely expensive to upgrade fully. |
| Mysterious X | Analysis: A hybrid unit that can stun enemies with his ability while also providing decent damage. He is a jack-of-all-trades but doesn’t excel as a pure DPS or pure support, and his upgrades are costly. |
| Ikki (Hollow) | Analysis: This form of Ikki offers very good DPS and range and is relatively cheap to upgrade compared to other 5-stars. His main weakness is a very long attack interval, which can leave gaps in his damage output. |
| Kujo | Analysis: Kujo boasts excellent DPS and a short attack interval, making him a consistent damage dealer. However, his very short range makes him difficult to place effectively, limiting his overall impact compared to other top-tier units. |
| Explosion Artist | Analysis: As a flying unit, Explosion Artist has amazing range and can bypass ground-only obstacles. His DPS is decent, but he is outshined by many other 5-star units that offer more specialized power. |
| Ramen Grill Master | Analysis: This unit is essential for economic management. He generates cash every turn, allowing you to afford your most expensive units and upgrades much faster. While he offers no combat utility, the financial advantage he provides is invaluable. |
| Shirtless Magician | Analysis: An outstanding 4-star support, Shirtless Magician freezes enemies with his attacks. His range becomes amazing when upgraded, making him one of the best early-to-mid-game crowd control units available. His personal DPS is low, as expected for a support. |
A-Tier Characters
A-Tier units are the backbone of many solid teams. They are highly effective, reliable, and often easier to obtain than their S and Meta-Tier counterparts, making them fantastic choices for all players.
| Character | Detailed Analysis / Pros & Cons |
| Kosuke (TS) | Analysis: This version of Kosuke has excellent range and respectable DPS for a hill unit. His performance is significantly boosted when paired with Zaruto (Sage), making them a powerful duo. |
| Borul | Analysis: Borul is a meta 4-star unit for the early game. He has amazing range, excellent DPS, and is great for breaking shields. His only real downside is that his upgrades can feel expensive for his rarity. |
| Janji | Analysis: An exceptional 4-star unit who applies a potent burn effect. He has decent DPS and range, and his effectiveness increases when teamed up with Ruffy, but he is held back by a very narrow line AoE. |
| Ikki (Halfmask) | Analysis: A top-tier 4-star unit for the early game. He offers excellent DPS and range for his rarity and is cheap to deploy and upgrade, though his attack speed is somewhat slow. |
| Super Koku | Analysis: This 4-star hill unit has excellent range. His true potential is unlocked when he is on a team with Vegu (Mind), as their synergy provides a massive power boost. On his own, his DPS is relatively low. |
| Dual Servant | Analysis: Dual Servant excels at single-target damage with very high DPS and decent range. His main drawback is a slightly long attack interval and a lack of any team synergies to boost his power further. |
| Nezichi | Analysis: Nezichi is a specialized damage dealer who is extremely powerful against bleeding enemies. She is nearly useless without a unit like Humble-Swordman to apply bleed first, but with that synergy, her DPS is incredible. |
| Stampede | Analysis: One of the best 4-star units for the early game, Stampede has very good range and DPS and is a good shield-breaker. His slow attack speed and small AoE hold him back from higher tiers. |
| Zaruto (Sage) | Analysis: A strong ground unit with very good range and DPS, especially when paired with Kosuke (TS). He is a good shield-breaker but is not worth using without his partner unit. |
| Ruffy (Lobby) | Analysis: An excellent 4-star hill unit with great range, DPS, and shield-breaking capabilities. His power is further enhanced when teamed with Janji. His upgrades can be a bit costly. |
| Vegu (Mind) | Analysis: This unit provides good DPS but is hampered by a long skill cooldown and only decent range, placing him firmly in the “strong but not exceptional” category. |
| Nighty | Analysis: Nighty’s strength is his rapid attack speed and decent DPS. This makes him good for consistent damage, but his low range is a significant disadvantage on many maps. |
B-Tier Characters
B-Tier units are solid choices that perform well but are a clear step down from the elite tiers. They are often good transitional units or fill specific niche roles effectively.
| Character | Detailed Analysis / Pros & Cons |
| Ice Queen | Analysis: Her ability to freeze enemies is very useful for a 3-star unit, providing excellent early-game crowd control. Her low damage and slow attack speed mean she is purely a support who gets replaced later. |
| Humble-Swordman (Selection) | Analysis: His value comes from applying a bleed effect, which enables powerful units like Nezichi. His own DPS is decent, but his very slow attack speed makes him a liability without a proper team. |
| Zio Brundo | Analysis: He boasts an extremely low attack interval for a 4-star unit, but this speed doesn’t compensate for his otherwise average damage and high upgrade costs, making him less efficient than A-tier options. |
| Koro (Lobby) | Analysis: An excellent early-game shield breaker due to his full AoE and fast attacks. His very short range and low single-target DPS make him ineffective once shields are down or against bosses. |
| Gen | Analysis: A respectable 4-star unit for early progression with decent all-around stats. However, he gets outclassed by stronger 4-stars and has expensive final upgrades for the power he provides. |
| The Cursed One | Analysis: He deals 2.5x damage on every third attack, giving him high burst potential. However, his very short range and small AoE make it difficult to apply this damage effectively, and he needs to be maxed out to be useful. |
| Vegu | Analysis: As a 3-star hill unit, his amazing range and decent DPS make him very good for the Story mode. His power spikes when paired with Koku, but he has limited placement options. |
| Kosuke | Analysis: This 3-star version of Kosuke is a solid all-around DPS that can stun enemies and apply a damage-over-time effect. He’s excellent against early bosses but is held back by his limited range. |
| Koku | Analysis: The 3-star Koku has excellent range for his tier and decent damage. He is significantly more powerful when teamed up with Vegu but suffers from a very long attack interval on his own. |
| Whitestache | Analysis: In this tier, Whitestache is seen as a good DPS unit with a full AoE, but his long attack interval holds back his potential, making him less reliable than his S-Tier counterpart. |
| Kujo | Analysis: While having good DPS and attack speed, his terrible range is a major flaw that makes him a B-Tier unit, as he struggles to contribute on many maps. |
| Blackstache | Analysis: A less potent version of the meta support, this Blackstache still offers good slowing utility but with less range or uptime, making him a solid but not game-breaking choice. |
| Xerxes | Analysis: A good overall unit that is unfortunately held back by an expensive upgrade path for the moderate power he brings to the table. |
C-Tier Characters
C-Tier units are generally considered average or situational. They can be useful for players who are still filling out their roster but are quickly replaced by more powerful and efficient options.
| Character | Detailed Analysis / Pros & Cons |
| Water Goddess | Analysis: The base form of this unit has decent AoE damage and range but is held back by a mediocre attack speed, making her a passable but unexceptional choice for wave clearing. |
| Borul | Analysis: The unevolved Borul offers good range and DPS for his tier but is very expensive to upgrade for the value he provides, making him less efficient than other options. |
| Stampede | Analysis: While having good range and high DPS for a lower-tier unit, his slow attack speed and small AoE make him unreliable for clearing dense waves of enemies. |
| Super Koku | Analysis: Without his synergy partners, Super Koku is a C-tier unit with decent AoE but expensive upgrades and underwhelming damage for the cost. |
| Nezichi | Analysis: In this context, Nezichi has high single-target DPS but is almost useless without a bleed-applying unit, making her extremely situational and often a dead slot on a team. |
| Dual Servant | Analysis: A unit with good damage and decent range, but his expensive upgrades and lack of AoE or utility make him a poor choice compared to more versatile units. |
| Koro (Lobby) | Analysis: While he attacks quickly in an AoE, his starting range is so short that he is often ineffective until fully upgraded, by which point other units are a better investment. |
| Zio Brundo | Analysis: His massive DPS potential is offset by his “mid overall” performance, suggesting his damage is inconsistent or difficult to apply effectively. |
| Xerxes | Analysis: Good overall stats are unfortunately overshadowed by an expensive upgrade path, making him a C-tier unit that is rarely worth the investment. |
| The Cursed One | Analysis: His damage gimmick is powerful, but his low range and small AoE mean he rarely gets to use it effectively against moving targets. |
| Onwin | Analysis: Without the potency of his meta version, this Onwin offers weaker buffs and damage, making him a decent but not essential support. |
| Gen | Analysis: A good overall 4-star unit that unfortunately proves ineffective against higher-level enemies, limiting his usefulness past the early game. |
| Anti Magician | Analysis: A decent starter unit with good range and damage for the very early game. He is cheap but quickly becomes ineffective against stronger enemies. |
| Ikki (Early) | Analysis: This version of Ikki is very cheap and pairs well with Ice Queen, but he offers very little on his own, with mediocre stats across the board. |
| Jon Jo | Analysis: Offers high initial DPS for a 3-star unit but is severely limited by his short range and single-target focus, making him poor at clearing waves. |
| Vegu | Analysis: A good unit for clearing the story mode due to his hill placement, but his utility is extremely limited beyond that specific purpose. |
| Zaruto | Analysis: A decent starter DPS unit whose low range and limited potential make him one of the first units you will replace. |
| Kosuke | Analysis: His stun ability and good range are useful, but his very low DPS makes him a poor choice for a primary damage dealer. |
| Spirit Detective | Analysis: A classic starter unit with decent stats for the first few levels but is quickly outclassed in every way by almost any other unit you can summon. |
| Lami | Analysis: A decent full AoE 3-star unit with good range, but her long attack interval and high total cost for a starter unit make her an inefficient choice. |
| Humble Swordsman | Analysis: While he applies bleed and has a full AoE, his very short range and low overall damage make him a weak link in most team compositions. |
| Koro | Analysis: A starter unit with a good attack speed but abysmal range and very low damage, making him one of the weakest units in the game. |
| Ruffy | Analysis: As a hill unit, he has good range and DPS for a 3-star, but being limited to hill spots and only hitting one target makes him highly inflexible. |
| Captain | Analysis: His burn application is his only notable feature. A long attack interval makes him one of the least effective units for clearing waves. |
| Uru | Analysis: As a hill unit, he has good range for his tier, but his damage is very low, and he is only effective against bosses, making him far too specialized and weak for general use. |
D-Tier Characters
D-Tier units are the weakest in the game. They should be replaced as soon as possible, as they offer very little utility or damage and will struggle to clear even early-game content.
| Character | Detailed Analysis / Pros & Cons |
| Spirit Detective | Analysis: A quintessential D-Tier unit. His stats are passable for the first few waves of the game and nothing more. He lacks any notable strengths and is quickly and easily replaced. |
| Uru | Analysis: While being a hill unit gives him placement advantages, his DPS is pitifully low, and his “boss killer” niche is ineffective due to his weak damage. He is a very poor investment. |
| Anti Magician | Analysis: The definition of a “mid overall” unit. He is cheap, but his performance is lackluster in every aspect, making him a unit to discard as soon as a better option is available. |
| Ikki (Early) | Analysis: Without his synergy partner, he is one of the weakest units. He is cheap, but his stats are too low to contribute meaningfully in any phase of the game. |
| Jon Jo | Analysis: His focus on single-target damage combined with a very short range makes him fundamentally flawed for a tower defense game where clearing waves of multiple enemies is key. |
| Vegu | Analysis: This base version is a weak hill unit whose limited placement options do not make up for his poor damage output and lack of useful abilities. |
| Zaruto | Analysis: As a starter unit, his low range and weak overall potential mean he serves only as a temporary placeholder until literally any other unit is summoned. |
| Kosuke | Analysis: While a stun is useful in theory, his extremely low DPS means enemies will walk right past him, making his utility moot. |
| Lami | Analysis: A unit whose high cost for a starter does not match her performance. Her slow attack speed makes her a poor choice for handling early enemy rushes. |
| Humble Swordsman | Analysis: The base version of this character has cripplingly short range and low damage, making his AoE and bleed effect almost useless in practice. |
| Koro | Analysis: Very short range and very low DPS make Koro one of the worst units to rely on. Even his fast attack speed can’t save him from being completely ineffective. |
| Ruffy | Analysis: A single-target hill unit with low damage. This combination of weaknesses makes him highly inflexible and a poor contributor to your team’s overall defense. |
| Captain | Analysis: His burn damage is negligible, and his incredibly long attack interval means he will let dozens of enemies pass by between attacks. He is a significant liability. |
