All Star Tower Defense X Units Tier List – August 2025

Roblox All Star Tower Defense X is here as the newest sequel to the All Star Tower Defense. To beat multiple enemies you encounter there, having the best units chosen from the  ASTD X tier list is the best way. When it comes to the All Star Tower Defense X units tier list, each and every one of them is varied by their effectiveness in the gameplay. So, this All Star Tower Defense tier list is made to help you identify the best and the worst for your fights. Let’s start.

Every Unit Ranked in the All Star Tower Defense X Units Tier List

We have ranked all the units in the ASTD X tier list update 3 based on their specific power levels as follows.

S Ranked Units 

These units can dominate in fights due to their high damage, unique abilities, or team synergy. So they are usually the top-ranked in the All Star Tower Defense X units tier list for any player.

The top units we can recommend from this rank are:

Freiren

Few units can slow down enemies and dish out high area damage at the same time, but Freiren pulls it off effortlessly. Her wide range makes her perfect for Hill placement, and the slow effect she applies gives your team more time to react and finish off waves. She fits best in teams built around support synergy, especially when boosted by damage enhancers like Xero or King Kaoe. In long battles like Infinite mode or late-game Story stages, Freiren’s crowd control becomes a major advantage. She’s a great pick for any player who values both damage and utility in one unit.

Sakuna

When it comes to dealing with bosses, Sakuna gets the job done fast. Her single-target damage is already high, but the real value lies in her fast attack rate and bleed effect, which keeps draining enemy HP even after the hit lands. Her performance improves even more when paired with buffers like Airren or The Strongest One, helping her shred high-HP enemies with ease. After ascension, her bleed damage increases further, making her a go-to choice for Story mode and PvE stages that are heavy on powerful enemies.

Super God Koku

Super God Koku brings both strong area damage and impressive range to the team, making him one of the more reliable picks for both Infinite and Story modes in this All Star Tower Defense X units tier list. His attacks hit multiple enemies at once, and once evolved, he gains a burn effect that adds more damage over time. Units like Kosuke (TS) or Ramen Grill Master help him reach his full potential by enhancing his overall synergy. For players who want a well-rounded DPS unit with long-term value, Super God Koku is a solid investment.

Chrollo

Chrollo brings more than just damage to the team. His attack buff boosts the whole squad’s power by twenty-five percent for six seconds, which can make a huge difference during tough waves or boss phases. He also has a stun ability that stops enemy progress, adding a layer of control to your strategy. Thanks to his support role, Chrollo pairs nicely with strong DPS characters like Sakuna or Super God Koku. With ascension, both his buff and stun effects become more powerful, helping the whole team perform better in PvE challenges.

BOX

Armored enemies and bosses do not stand a chance when BOX is on your team. He focuses on single-target damage and comes with a unique shield-breaking skill that tears through tough defenses. His fast attack speed keeps the pressure on, allowing him to deliver steady and deadly hits. Units like Blackstache or Slayer Mage boost his usefulness even more, either by slowing enemies down or joining in on the shield-breaking. Once BOX is ascended, his power against shielded enemies increases, making him a top-tier choice for players tackling end-game content.

A Ranked Units

Rank A units in this All Star Tower Defense X units tier list are also the reliable, strongest picks with great skills, synergy, and a better damage capacity.

If you want to pick the best here, the following are the best units we can recommend to you from the A rank in this ASTD X tier list upd 3.

Onwin 

Support units that actually impact the game flow are rare, and Onwin is one of the best examples. Not only does he summon mini-units to help fight, but he also gives the whole team a twenty percent attack boost for five seconds. That makes a huge difference during high-pressure moments. His synergy is strongest with high-damage units like Sakuna or Venus, allowing their output to go even higher. Onwin’s ascension upgrades his summoned units, making him even more effective as a support core. If team balance is your focus, Onwin belongs in your roster.

Airren

Airren’s flexibility makes her stand out right away. She can switch between dealing area damage in her giant form and summoning support mode, giving you two styles of wave control in one unit. This kind of adaptability makes her a reliable pick for players who want one unit to fill multiple roles. She pairs especially well with balanced units like Freiren or Spider Boss for a mix of raw damage and crowd control. Her ascension increases her AoE range, pushing her value even higher for both Story and Infinite runs.

Venus

There’s nothing more satisfying than locking down a boss right before it strikes, and Venus does exactly that. Her three-second stun along with strong single-target damage makes her deadly in boss stages and enemy-heavy waves. She works beautifully with Onwin or Chrollo, who both increase her damage potential. Once she’s ascended, her stun lasts longer, making her even better at stopping enemy threats before they snowball. Venus is a solid pick for players who want both power and control in one unit.

Spider Boss

Spider Boss in the All Star Tower Defense X units tier list brings serious control to any team with her wide-area attacks and web-based slow effect that lasts four seconds. The twenty percent slow might not sound huge on paper, but when combined with other support units, it stacks up nicely. Her Hill placement lets her hit from a distance while staying out of harm’s way. She works great alongside Freiren or Xero, especially in crowd-heavy scenarios. Ascension improves the slow effect even more, which helps delay large groups of enemies during Infinite mode or advanced Story chapters.

B Ranked Units

If you need some good units from the All Star Tower Defense X units tier list, go with the B rank. They are also reliable and have the exact skill sets that allow you to beat down even the hardest enemies.

And the best picks from this rank are:

Borul

Borul is a great pick for early players looking for reliable damage and simple utility. He delivers solid area damage and can break enemy shields using his multi-hit attacks, which is especially helpful in the early waves of Story or Infinite modes. Thanks to his Hill placement and decent range, he can hit from a safe spot and cover wide paths. He works well with units like Kosuke (TS) or Ramen Grill Master, who boost his overall performance. After ascension, his damage and range get even better, making him a smart investment for beginners building their core team.

Janji 

Burn damage fans will enjoy what Janji brings to the team. His single-target attacks come with a steady burn effect, dealing eight percent damage over four seconds. While he is not the flashiest DPS unit, his consistent output makes him a good fit for teams that need sustained damage over time. He blends nicely with Ruffy (Lobby) or Airren, both of whom can help create a smoother overall flow in battle. Once ascended, Janji’s burn becomes stronger, giving him more presence in mid-level content.

Shirtless Magician 

Crowd control becomes a lot easier when you’ve got Shirtless Magician in your squad from the All Star Tower Defense X units tier list. He can freeze enemies for three seconds while also dealing moderate area damage, making him a strong pick for both support and offense. His long range and Ground placement allow him to cover tricky lanes effectively. He works well with other control-focused units like Freiren or Spider Boss, allowing for smoother wave clearing. Ascension gives him a longer freeze duration, which helps a lot during high-pressure fights. He’s especially good for new players trying to manage tougher enemy groups early on.

C Ranked Units

You can go with a C-ranked unit in the All Star Tower Defense X units tier list if you are seeking a good performance. These are beginner-friendly and will manage to do some great performance with a bit of effort as well.

So, as usual, the top picks we recommend from this rank are:

Humble Swordsman

Humble Swordsman is a simple but effective unit for new players looking to handle early waves. His area attacks hit multiple enemies, and the shield-breaking potential gives him extra value against tougher spawns in the early Story chapters. While his damage output is not overwhelming, it gets the job done and improves slightly after ascension. He works best when paired with Kosuke (TS) or Ramen Grill Master, both of whom offer small boosts that help his wave-clear role. If you're just starting out, he's a handy pick to build your first lineup around.

Jon Jo

Jon Jo is the kind of unit in this All Star Tower Defense X units tier list you can rely on early in the game when waves come fast and often. His multi-hit area attacks allow him to cover ground enemies quickly, and he starts off with solid DPS that holds up well through the first few Story arcs. He matches well with units like Borul or Zorro, who also focus on wide AoE damage. Once ascended, his attack speed gets a bump, making him even more useful in repeated wave clearing. For beginners, he offers a strong mix of simplicity and damage.

Uru

Uru comes through when you need a focused unit to handle early bosses as the next pick for the C rank in this All Star Tower Defense X units tier list. His single-target damage is strong right out of the gate, and his good range helps him stay safe while dishing out consistent hits. As a Hill unit, he is easy to place in safer spots where he can keep firing without interruption. He benefits from teaming up with support units like Shirtless Magician or Onwin, who can provide minor damage boosts. Once evolved, his damage becomes even more reliable, making him a smart choice for players trying to push through early boss fights.

D Ranked Units

D-ranked units are not the best to focus on. Every unit you see under this rank from the All Star Tower Defense X units tier list shows an average performance with average skills. They are not your best picks, so it is better to swap them whenever you can.

Koro

Koro is a quick-hitting unit ideal for clearing waves of weak enemies early on. His area attacks combined with a bleed effect (5% over 4 seconds) make him a decent pick for beginner teams trying to stay ahead of early Story mode pacing. Though his base stats aren’t overwhelming, the fast attack speed gives him an edge when dealing with swarms. He works best when teamed with units like Ramen Grill Master or Kosuke (TS), who support his AoE playstyle. Evolving him into Koro (Lobby) brings better numbers overall, so it’s worth doing if you’ve got the extra resources.

Zio Brundo

Zio Brundo brings reliable single-target damage that helps take down early-game bosses. He doesn’t shine in flashy AoE, but his consistency and decent range make him a nice pickup for early PvE or Story stages. As a Red Ground unit, he works well alongside characters like Borul or Humble Swordsman, forming a simple but balanced damage core. Ascension improves his damage enough to stay relevant longer, but he’s most useful as a bridge until you get higher-tier boss-killers. For newer players, he offers just enough power to be worth using.

F Rank

F rank units in the All Star Tower Defense X units tier list are the worst. They are not skilled enough to make an impact on your gameplay at all. So, it is better to refrain from using them.

But still, some of the units in this rank are also giving an okay performance, so here are who we recommend to you from this rank of ASTD X tier list.

Ice Queen

Slowing down enemy waves early in the game becomes easier with Ice Queen’s two-second freeze effect. She also deals modest area damage, making her a handy unit for controlling crowds in the initial Story stages. As a Blue Ground unit, she pairs well with wave-clearers like Humble Swordsman or Jon Jo to keep enemies manageable. While her ascension slightly extends the freeze duration, she’s mostly useful as an early-game support before upgrading to stronger units like Shirtless Magician for improved control and damage.

Captain

Captain stands out in the All Star Tower Defense X units tier list for his steady single-target damage paired with a burn effect that lasts three seconds. This combination makes him effective against early-game bosses where sustained damage is key. Being an Orange Hill unit allows for safe positioning, maximizing his damage uptime. He fits well in basic DPS teams alongside Koro or Zio Brundo. His ascension brings a small boost to burn damage, helping him stay relevant until you can transition to stronger B-tier or higher units like Borul.
