Meta Hybrid – Units that can attack both ground and air
-
Meta Air – Best units for air lanes
-
Meta Ground – Strongest ground-only damage dealers
-
Meta Support – High-impact support units
-
Good Support – Useful, but not meta-defining
Good Support Tier
These units provide solid utility but are not game-changing on their own:
-
Shikamaru – Slows enemies and provides minor control
-
Hu – Reliable general support
-
Rock Lee – Decent buffs and utility
-
Rukia – Situational crowd control
-
Zoro – Simple and effective support damage
They work well early and mid-game but usually get replaced later.

Speedwagon – Only farm unit, mandatory in almost every run
-
Sakya – Time stop, consistent support, and strong damage
-
Akinu – Top-tier debuffs, burn damage, and team support
-
Shanks – Passive buffs that boost team efficiency
-
Lelouch – Complex but powerful control and air coverage
Meta Air Tier
Best units for handling flying enemies:
-
Ace – Best air DPS, strong burn damage
-
Genos – Infinite scaling but high-risk playstyle
-
Lelouch – Can hit air but harder to use effectively
Ace remains the safest and strongest pick for air lanes.
Meta Ground Tier
Top-performing ground-only units:
-
Kyuto – Still dominant, especially in Virtual Realm
-
Sasuke – High DPS, stuns, dodge mechanics, and burn
-
Law – Elite boss killer with teleport utility
-
Isagi – Strong boss-focused damage
-
Obito – Reliable early-game ground unit
Kyuto remains a must-have for Virtual Realm grinding despite nerfs.
Meta Hybrid Tier
Hybrid units are the backbone of most endgame teams:
-
Sun Jin Woo – Best hybrid unit in the game
-
Ragna – Massive damage after buffs, early hybrid access
-
Kenpachi – Armor shred, debuffs, and insane DPS
-
Sakya – Hybrid upgrade plus strong utility
-
Mob – High damage with support effects, but expensive
Hybrid units dominate most modes due to flexibility.
Top 10 Meta Overall Units
Here are the 10 strongest units in Universal Tower Defense right now:
1. Sun Jin Woo
The best unit in the game. Insane damage, summons, buffs, and broken etherealization. No pity system makes him hard to get, but absolutely worth it.
2. Ragna
Recent buffs pushed him to top-tier. Deletes enemies during his power window and gains hybrid early.
3. Sakya
Time stop, hybrid access, strong DPS, and consistent utility. One of the most underrated units.
4. Kenpachi
Top-tier mythic DPS with armor slicing and debuffs. Expensive and one-placement, but devastating.
5. Kyuto
Still broken, especially in Virtual Realm. Ground-only holds him back slightly outside that mode.
6. Sasuke
Reliable DPS, stuns, dodge mechanics, and strong burn damage. Very safe and consistent.
7. Akinu
Easy-to-use hybrid support with burn, confusion, and team buffs. A must-have legendary.

Elite boss killer with teleport control. Strong damage plus utility makes him extremely valuable.
9. Ace
Best air unit in the game with excellent burn damage and scaling.
10. Mob
Strong hybrid DPS and support, but outclassed by newer top-tier units.
