S Tier Units (Meta Definers)
These are the units that shape the meta in All Star Tower Defense X. They offer unmatched DPS, utility, or support value and are strong across Story, Infinite, and PvP.
If you’re lucky enough to pull one of these, it’s worth building your entire strategy around them since they can carry entire runs even with limited team support.

| Dark | Black flame damage + AoE | Mediocre early DPS |
| Sky God | Shock debuff + DPS | High cost, slow SPA |
A Tier Units (Reliable Powerhouses)
A-Tier characters may not be quite as broken as the top-tier picks, but they’re still excellent in almost every game mode.
They provide consistent damage, strong utility, or flexible roles that make them reliable additions to most teams.
If you don’t have S-Tier options, these are your best alternatives to push progression smoothly.

| Tomi | Good value overall | Needs leveling to shine |
| Mercury Guardian | Strong early DPS | Costly to place/upgrade |
| Neymar (Trapper) | Huge damage maxed | Hill-only |

B Tier Units (Good but Situational)
These units can definitely pull their weight, but they often rely on the right setup, mode, or support to shine.
Some are budget-friendly early-game units, while others are overshadowed by stronger versions of similar roles.
They’re good mid-tier fillers, but you’ll eventually want to replace them once you secure stronger pulls.
| Unit | Pros | Cons |
|---|---|---|
| Tony Stark | Great range & DPS | Average SPA |
| Zesty General | Cheap upgrade, solid early DPS | Long SPA |
| BOX | Decent damage & SPA | Low range |

| Ikki (HalfMask) | Reliable DPS | Long SPA |
| Blackstache | Good DPS | Long SPA, low range |
| Expert Sorcerer (Serious) | Decent hybrid damage | Expensive to run |
C Tier Units (Average, Story Mode Friendly)
C-Tier characters are mostly useful for beginners or for clearing early Story stages. They may look strong at first but quickly fall off as you progress.
They can still be fun or useful if you lack better summons, but they’re generally outclassed once you unlock higher tiers. Consider them stepping stones rather than long-term investments.
| Unit | Pros | Cons |
|---|---|---|
| Future T | Good range & DPS | Hill-only |
| Anti Magician (Demon) | Solid DPS | Weak range |
| Water Goddess | Good AoE & range | Decent SPA |
| Borul | Strong damage output | Costly |
| Stampede | Strong AoE & DPS | Small AoE size |
| Super Koku | Decent DPS + AoE | Expensive |
| Nezichi | High DPS early | Bad scaling |
| Dual Servant | Decent DPS & AoE | Costly |
| Koro (Lobby) | Quick AoE | Weak range early |
| Zio Brundo | Very high DPS | Mid scaling |
| Xerxes | Good hybrid | Costly |
| The Cursed One | Multiplier damage | Low AoE |
| Onwin | Decent AoE & SPA | Expensive |
| Mbappe (Copycat) | 4★ but useful | Line AoE only |
| Gen | Decent 4★ | Weak against higher mobs |
| Expert Sorcerer | Balanced DPS | Low range |
| Kuroma | Decent DPS | Average overall |
| Ruwabara | Decent SPA | Low DPS |
D Tier Units (Starters, Replace ASAP)
D-Tier units are best thought of as training wheels. They’re fine for brand-new players who just need something to get through the first few waves, but their poor scaling and limited utility mean you should replace them as soon as possible.
Once you pull almost any higher-tier unit, these should be rotated out of your lineup.
| Unit | Pros | Cons |
|---|---|---|
| Masochist Lady | Cheap DPS | Weak overall |
| Freezer | Decent early DPS | Average scaling |
| Handsome-Jo | Decent early DPS | Hill-only |
| Ice Queen | Freeze utility | Long SPA, low DPS |

| Vegu | Story clear help | Hill-only |
| Zaruto | Starter DPS | Low range |
| Kogan (Kid) | Cheap DPS | Low output |

| Spirit Detective | Decent starter | Bad scaling |
| Lami | Decent early DPS | Too costly |

| Koku | Good starter | Long SPA |

Final Thoughts on the ASTDX Tier List
That wraps up our All Star Tower Defense X Units Tier List (August 2025). With dozens of units inspired by anime icons, the real challenge isn’t just pulling new characters but knowing which ones are worth keeping in your lineup.
The S-Tier meta units like Michishibo, Slayer Mage, and Ziek (Beast Giant) can carry you through almost every mode, while A and B-Tier units give you reliable backup until you land those top-tier summons.
Remember, lower-tier characters aren’t completely useless, they can still help you clear early Story stages or act as placeholders until your gem farming pays off. As new updates drop, balance changes will continue to shift which units dominate Infinite or PvP, so keep an eye on banners and stay flexible with your team.
Which units are you running in your current deck? Have you pulled any S-Tier units yet, or are you making the most out of A and B-Tier supports?
