Universal Tower Defense is not just about placing towers and watching waves fall. Every clear, especially in harder modes like Infinite, Nightmare, Challenges, and Virtual Realm, depends on which units you invest in and how well they scale over time. With limited slots and expensive upgrades, choosing the wrong unit can slow your progression dramatically.

S Tier: Meta-Defining Units
These units sit at the top because they shape the entire meta. They either scale infinitely, erase bosses, or provide utility no other unit can replace.
| Unit Name | Role |
|---|---|
| Sung Jin-Woo (Monarch) | Hybrid |
| Ragna | Hybrid |
| Dragon Silver | Hybrid |
| Zaraki (Kenpachi) | Hybrid |
| Kirito (Kyito) | Ground |
Sung Jin-Woo (Monarch)
Role: Hybrid
Sung Jin-Woo is widely considered the strongest unit in Universal Tower Defense. His shadow army mechanic allows him to summon additional fighters that scale over time, turning him into a late-game monster. The longer a run goes, the stronger he becomes, making him unmatched in Infinite mode.
Ragna
Role: Hybrid
Ragna follows a self-awakening mechanic where he stuns himself temporarily, then returns with massive buffs. Once awakened, he deletes high-HP targets and bosses with ease. His burst damage makes him one of the best boss killers in the game.
Dragon Silver
Role: Hybrid
Dragon Silver combines strong damage with freezing mechanics. His Silver Battle Trance boosts his damage output significantly, allowing him to control waves while melting tanky enemies. He excels in slower game modes where stalling matters.
Zaraki (Kenpachi)
Role: Hybrid
Zaraki brings something unique: he removes elemental disadvantages from enemies. This alone makes him incredibly valuable in mixed-content runs. On top of that, his full-area damage keeps waves under control consistently.
Kirito (Kyito)
Role: Ground
Kirito ramps up through his Virtual Mode, gaining critical damage and attack boosts. Once fully powered, he functions as a hyper-carry that can solo difficult sections when supported correctly.
A Tier: High-Value Utility and Control
A Tier units may not always top damage charts, but they provide game-winning support and control that makes S Tier units even stronger.
| Unit Name | Role |
|---|---|
| Miku | Support |
| Sakuya | Support |
| Lelouch (Lulu) | Support |
| Scarlet | Support |
| Law | Ground |
Miku
Role: Support
Miku is the best buffer in the game. Her music tracks increase damage or range for nearby units, massively boosting overall DPS. She shines in Infinite mode once you have your core damage dealers placed.
Sakuya
Role: Support
Sakuya offers time-stop, stuns, and self-scaling damage. She is especially strong in Virtual Mode content and pairs well with high-damage carries that benefit from extra control.
Lelouch (Lulu)
Role: Support
Instead of raw damage, Lelouch manipulates enemy movement. His retreat and stall mechanics force enemies to walk backward or freeze in place, buying precious time during difficult waves.
Scarlet
Role: Support
Scarlet reduces cooldowns for Royalty units and provides time-stop effects. She is extremely effective in coordinated team setups and shines in Infinite mode.
Law
Role: Ground
Law’s Room ability targets the strongest enemies anywhere on the map, making him excellent for eliminating leaks or priority targets. Among non-secret units, he offers some of the best late-game value.
B Tier: Strong but Outclassed
These units are reliable and useful, but they lack the extreme scaling or unique mechanics that define higher tiers.
| Unit Name | Role |
|---|---|
| Sasuke | Hybrid |
| Ace | Hill / Air |
| Akainu (Admiral Magma) | Hybrid |
Sasuke
Role: Hybrid
Sasuke offers good damage and full-area stuns, making him solid in most content. However, he lacks infinite scaling, which keeps him out of S Tier.
Ace
Role: Hill / Air
Ace’s burn damage bypasses shields, making him a strong choice against flying enemies. He’s especially useful if you don’t have top-tier Air units yet.
Akainu (Admiral Magma)
Role: Hybrid
Akainu creates magma zones that damage and confuse enemies, forcing them backward. While still effective, his role is largely overshadowed by higher-tier hybrids with better scaling.
C Tier: Situational and Early-Game Picks
C Tier units work best early on or in very specific scenarios. Most players replace them once better options are available.
| Unit Name | Role |
|---|---|
| Zora | Ground |
| Genos | Hill / Air |
| Mob Psycho | Hybrid |
| Ruin Obito | Ground |
| Speedwagon | Support |
| Rock Lee | Air |
Zora
Role: Ground
Zora is one of the best early-game units, especially for free-to-play players. His traps provide stuns and damage, helping new players stabilize runs.
Genos
Role: Hill / Air
Genos deals strong damage to burning enemies, but his passive can stun himself for an entire wave, making his performance inconsistent.
Mob Psycho
Role: Hybrid
Mob offers minor slowing effects, but his damage output falls behind quickly in late-game modes.
Ruin Obito
Role: Ground
A free unit with decent burn damage and area control, but intentionally weaker than premium characters.
Speedwagon
Role: Support
Speedwagon doesn’t focus on combat. Instead, he generates currency, helping players afford expensive units earlier in a run.
Rock Lee
Role: Air
Rock Lee performs well early but struggles to keep up once enemy health scales heavily.
D Tier: Low Priority Units
These units are generally inefficient or heavily outclassed in the current meta.
| Unit Name | Role | Why This Unit Falls Short |
|---|---|---|
| Greybeard | Ground | Extremely weak for his rarity and cost, offering almost no value at any stage. |
| Goku | Ground | Starter unit with no scaling, utility, or late-game relevance. |
| Naruto | Ground | Starter unit that becomes obsolete once enemy health begins scaling. |
| Luffy | Ground | Limited damage and no synergy, making him ineffective beyond early waves. |
| Nami | Ground | Minor early-game usefulness with no meaningful mid or late-game impact. |
| Sanji | Ground | Acceptable early damage, but lacks range, scaling, and utility. |
| Zoro | Ground | Slightly better than other starters, but still heavily outclassed. |
| Gaara | Ground | Cheap to deploy and usable early, but performance drops off quickly. |
| Kakashi | Ground | Average damage with restrictive targeting limits his effectiveness. |
| Neji | Ground | Basic damage dealer with no standout mechanics or scaling. |
| Shikamaru | Support | Early slow effect helps briefly, but becomes irrelevant fast. |
| Shanks | Support | Kill-dependent buff makes him inconsistent as a support unit. |
| Isagi | Ground | Conditional buff mechanics make him unreliable, though still marginally better than most D-tier units. |
How to Get Better Units in Universal Tower Defense
New units are obtained through the Summon area, using gems. Managing your resources is important, especially if you’re targeting Secret or Mythic units.
Basic summoning steps:
- Open the Areas menu.
- Enter the Summon area.
- Use single summons or discounted multi-summons.
- Check banners carefully and wait for high-value units to appear.
Using active codes can significantly speed up this process by providing free gems.
Best Units for Early Game
If you’re just starting out, focus on:
- Zora
- Sasuke
- Ace
- Speedwagon
These units help stabilize early waves and build enough economy to transition into stronger late-game carries.
FAQs: Universal Tower Defense Tier List

Most D Tier units are not worth long-term investment. They lack scaling, utility, or late-game relevance and should only be used temporarily if no better options are available.
Q. What type of units are most important in late game?
Hybrid and Air units are crucial in late-game content because they can target multiple enemy types and scale better in modes like Infinite and Virtual Realm.
Q. How often does the Universal Tower Defense tier list change?
The meta can change with balance patches, new units, or evolutions. This Universal Tower Defense Tier List is updated regularly to reflect those changes and current unit performance.
