Ranking Factors for All Star Tower Defense X
Before we dive into the tier list, it is important to understand how I ranked these units. Not all units are created equal, and a high-damage unit isn’t always the best choice if it lacks utility. I evaluated units based on four key criteria:
- Damage Output (DPS): How much damage does the unit deal per second? This includes both single-target damage for bosses and Area of Effect (AoE) damage for waves.
- Cost Efficiency: Is the unit worth the investment? Some units are cheap and powerful early on, while others are expensive “money sinks” that pay off late game.
- Utility & Abilities: Does the unit have stuns, slows, buffs, or money generation? Support units often rank higher because they enable your damage dealers.
- Placement & Range: How much ground can the unit cover? Units with long range and good placement potential are vital for difficult map layouts.

Detailed Unit Analysis
In this section, I will break down the stats, strengths, and weaknesses of every unit listed above. This will help you decide which units are worth upgrading and which ones to trade away.
S-Tier Units Analysis
Zio (The World)
Zio is currently the king of crowd control in All Star Tower Defense X. Based on the popular anime character, Zio brings immense value with his “Time Stop” ability. This ability freezes all enemies in his radius, allowing your other units to freely deal damage without retaliation. His upgrade path offers incredible range, covering nearly half the map in some instances. If you are aiming for high wave clears in Infinite Mode, Zio is a non-negotiable pick for your team.
Borul (Warrior)
If you need raw damage, Borul is the unit you are looking for. He excels at single-target damage, making him the premier boss killer in the current meta. While he lacks AoE capabilities in his earlier upgrades, his final evolution turns him into a beast that can shred through millions of HP in seconds. He is expensive to place, so make sure you have a solid economy setup before investing heavily in him.
Speedster (Flash)
Speedster is arguably the most versatile unit in the game. As a hybrid unit, he can target both ground and air enemies, which is crucial for levels with surprise flying bosses. His attack speed is lightning fast, and his placement cost is reasonable compared to other S-tier units. I recommend using him as your primary damage dealer in Story Mode to breeze through levels quickly.
Rengoku (Flame)
Rengoku brings the heat with his powerful AoE attacks that inflict a “Burn” status effect. Damage over Time (DoT) is incredibly strong in ASTD X because it chips away at enemy health bars even after they leave his range. He is particularly effective on maps with long, winding paths where enemies are clumped together. Pair him with a stun unit like Zio for maximum effectiveness.
Idol (Music)
Every team needs a support, and Idol is the best in class. She does not deal damage herself, but she provides a significant damage boost to all units within her radius. This multiplier effect makes her essential for late-game content where enemy health scales exponentially. Additionally, she serves as a money generation unit in her earlier forms, helping you boost your economy in the early game.
A-Tier Units Analysis
Goko (Blue)
Goko is a reliable hybrid unit that serves as a great filler if you are missing an S-tier. He offers a balance of range and damage, though he doesn’t particularly excel in any single category. He is fantastic for players who are still building their roster and need a solid unit to clear the standard Story Mode stages. He can be evolved to increase his utility significantly.
Stampede (Ichigo)
Stampede is a powerhouse when it comes to crowd control. His AoE circles are massive, and he hits hard enough to clear waves of weaker enemies effortlessly. However, he struggles slightly against high-health bosses due to his slower attack animation. He is a must-have for farming specific resource stages where enemy density is high.
Genas (Curse)
Genas is a specialized unit focused purely on obliterating single targets. His damage output rivals that of Borul, but he suffers from shorter range. You need to place him strategically near the front lines to maximize his value. His “Curse” ability debuffs enemies, causing them to take more damage from subsequent attacks, making him a great combo starter.
Mochi (Doflamingo)
Mochi is a unique unit that uses strings to attack, trapping enemies in place. He offers a mix of damage and minor crowd control. While he isn’t as dominant as the top-tier stunners, his ability to hit multiple targets simultaneously makes him a strong contender for A-tier. He is particularly useful in events where enemies move unpredictably.
Jokato (Star)
Similar to Idol, Jokato serves a support role but with a focus on economy. He generates cash on kill or wave completion, allowing you to snowball your income early in the match. In his later upgrades, he gains the ability to slow enemies, adding decent utility to his kit. He is a staple for challenge runs where starting money is low.
B-Tier Units Analysis
Nuro (Tanjiro)
Nuro is a solid early-game unit that falls off in the late game. He has decent DPS and a relatively cheap upgrade cost, making him perfect for the first few worlds of Story Mode. However, his range is quite limited, and he lacks the heavy-hitting abilities of higher-tier units. Use him to get started, but replace him as soon as you pull something better.
Luffo (Gear 4)
Luffo brings decent AoE damage and a knockback effect. Knockback can be a double-edged sword; while it keeps enemies at bay, it can sometimes mess up the timing of your other units’ attacks. He is fun to use and viable for mid-game content, but he isn’t optimal for Infinite Mode where enemies have knockback resistance.
Pinky (Natsu)
Pinky is a fantastic starter unit. He deals AoE damage and is very cheap to place. Many players use him as a “decoy” unit or for selling and rebuying strategies in challenge modes. While he won’t carry you past the mid-game, he is excellent for farming early resources and XP.
Soul (Shinra)
Soul is a mobile unit that can hit both ground and air. His damage is average, but his attack speed is noteworthy. He fits well into teams that need a little extra firepower to cover blind spots. He is generally outclassed by Speedster, but remains a viable alternative if you are on a budget.
C-Tier Units Analysis
Zuzu (Jotaro)
Zuzu has a cool concept with a time-stop ability, but the duration is unfortunately too short to be reliable in high-level play. His damage is decent, but his range and cost efficiency hold him back. He is mostly used by collectors or fans of the character rather than competitive players.
Tony (Torirono)
Tony is a niche pick who focuses on raw attack speed but low damage per hit. Against high-defense enemies, his damage drops off significantly. He can be useful in early waves to chip away at fast enemies, but there are almost always better options available for that role.
Rocky (Rock Lee)
Rocky is a melee-range unit with high burst damage but zero range. This puts him at a severe disadvantage on maps where enemies move fast or have ranged attacks. He requires very specific placement to be effective and is generally considered a lower-tier pick for general play.
D-Tier Units Analysis
Basara (Sasuke)
Basara suffers from poor scaling. While he looks cool and has a hybrid tag, his damage numbers simply do not keep up with the rest of the roster. He consumes a lot of money for upgrades that yield very little return. It is generally recommended to use him as “feed” to upgrade other units rather than deploying him in battle.
Kagu (Kaguya)
Kagu is currently one of the most expensive units to upgrade for the value she provides. Her AoE is wide, but the damage is pitifully low compared to the investment required. She occupies a slot better used by almost any other unit in the game. Avoid investing in her unless you are doing a meme run.
How to Build the Best Team?
Creating the best team in All Star Tower Defense X isn’t just about stacking S-tier units. You need synergy. A balanced team typically consists of:
- 1-2 DPS Carries: (e.g., Borul, Speedster) to kill enemies.
- 1 Crowd Control Unit: (e.g., Zio) to stop enemies.
- 1 Support/Economy Unit: (e.g., Idol, Jokato) to boost stats and money.
