Update 4.0: New Units and Meta Shift
The transition from UTDX to Universal Tower Defense Z in 2026 has brought a massive influx of high-powered anime units. Update 4.0 specifically focuses on the summer event and the introduction of "Unrivaled" and "Sage" tier characters that redefine the current meta. To get every new unit, you must understand the distinction between standard summons and event-limited banners.

| Unit Name | Tier | Primary Role | Acquisition Method |
|---|---|---|---|
| Joyful Captain | S+ | DPS / Support | Banner Summon / Evolution |
| Jinoo (Shadow Monarch) | S+ | Scaling DPS | Limited Time Banner |
| King Sailor (Unrivaled) | S+ | AOE / Leader | Event Summon |
| Ancient Mage (Sage) | S+ | Utility / Burst | High-Tier Summon |
| Alpha Devil (Omega) | S | Stun / Event | Special Event Rewards |
| Triple Threat (Unrivaled) | S | Bleed / Boss Killer | Evolution System |
Focus your resources on Joyful Captain first. This unit provides a unique blend of high damage and support utility that remains relevant in both Infinite and Raid modes, making it the most efficient "new" unit to target in the 2026 Meta.
How to Get Units: Summoning and Currency
Summoning is the primary way to expand your roster in Universal Tower Defense Z. However, simply clicking "Summon" is not enough to get every unit. You need to manage multiple currencies and understand banner rotations. The game currently utilizes Gems, Universal Gems, and specialized Tickets to gate access to different rarity tiers.
Standard Gems
Used for basic unit summons. These are easily farmed through Story Mode and Virtual Realm clears.
Universal Gems
A premium currency often rewarded via Codes or high-level Raids. Essential for "Season" specific units.
Ruler Tickets
Rare tickets used for the highest tier banners. These should be hoarded for Update 4.0 meta-defining units.
| Currency Type | Best Farming Location | Recommended Use |
|---|---|---|
| Gems | Story Mode / Infinite | Early game roster building |
| Universal Gems | Raids / Event Modes | Season 1 Part 1 & 2 units |
| Summer Currency | Summer Event Stages | Summer limited units |
| Gold | Virtual Realm | General upgrades and materials |
Always check the "Codes" menu before summoning. Developers frequently release codes like ReapersVsHollowDestroyers which provide thousands of Gems and Trait Rerolls, significantly lowering the barrier to entry for new units.
The Evolution and Etherealize Path
Many of the "new" units in Universal Tower Defense Z cannot be summoned in their final form. Instead, you must summon a base version and progress through the Evolution and Etherealize systems. This is where most players get stuck, as it requires specific fragments and materials found only in late-game modes.
Summon the Base Unit
Acquire the base version of a unit (e.g., Jinoo) from the summoning area using Gems or Tickets.
Leveling to Max
Use the unit in Story Mode or Infinite to reach the level cap. You cannot evolve a unit that hasn't reached its base potential.
Gather Evolution Materials
Farm Raids for specific fragments (Ocean, Sky, or Universal Fragments). Some units require "Alpha Swords" or "Ruler Souls."
Evolve and Etherealize
Access the Evolution menu to transform the unit. Use Etherealization Shards to further boost stats and unlock hidden passives.
| Evolution Material | Source Location | Associated Units |
|---|---|---|
| Universal Fragments | World Raids | Most S+ Tier Units |
| Ocean Fragments | Challenge Modes | Water-themed / Summer Units |
| Sky Fragments | Infinite Mode (Wave 50+) | Hill and Hybrid Units |
| Ethereal Shards | Ultra Boss Fights | All Etherealized Forms |
Do not waste your Etherealization Shards on B-Tier units. Evolution is expensive, and materials are scarce. Only invest in units labeled as S+ or S in the tier list to ensure your team can handle the 2026 late-game content.
Farming Modes for Unit Acquisition
To get every unit, you must participate in all game modes. Each mode in Universal Tower Defense Z is designed to provide a specific piece of the puzzle. While Story Mode gives you the Gems to summon, Raids and Challenges provide the materials to make those units viable.
| Game Mode | Primary Reward | Difficulty | Best For |
|---|---|---|---|
| Story Mode | Gems / Account XP | Easy - Medium | New player progression |
| Challenges | Upgrade Materials | Hard | Testing team strength |
| Raids | Evolution Fragments | Very Hard | Mid-to-late game growth |
| Virtual Realm | Gold / Steady Income | Medium | Grinding for upgrades |
| World Raid | Rare Boss Drops | Extreme | Co-op endgame players |
| Event Modes | Seasonal Units | Variable | Limited-time rewards |
Weekly Unit Goals:
- Redeem all active codes for Trait Rerolls and Gems
- Complete 10 Raid runs to stockpile Universal Fragments
- Reach Wave 100 in Infinite to farm Sky Fragments
- Clear the Summer Event stages for limited currency
- Evolve at least one A-Tier unit to S-Tier status
If you are struggling with Raids, focus on building a support unit like Bulmo or Virtual Idol. Even if you lack the top DPS units, providing economy or range buffs makes you a valuable teammate in co-op sessions, allowing you to "leech" materials from stronger players.
Traits and Rerolls: Optimizing Your Units
Getting the unit is only half the battle; the other half is ensuring it has the right Traits. A unit with a "Godly" or "Unique" trait can perform up to 50% better than the base version. In Universal Tower Defense Z, you use Trait Rerolls (obtained via codes and raids) to roll for these powerful modifiers.
| Trait Name | Effect | Priority |
|---|---|---|
| Godly | Massive Damage & Range boost | Highest |
| Unique | Unit-specific special ability | High |
| Golden | Increased Gold production (Farm units) | High (Bulmo only) |
| Swift | Reduced Cooldowns | Medium |
When rerolling, use Stat Locks to protect high-tier rolls while you chase a better overall stat line. Never use Stat Locks on units you plan to replace in the next update.
Universal Tower Defense Z FAQ
Q: How do I get the Joyful Captain in Update 4.0?
The Joyful Captain is obtained through the premium summoning banner using Ruler Tickets or Universal Gems. Once summoned, you can evolve him using Universal Fragments found in Raids.
Q: What is the fastest way to farm Gems for summoning?
The fastest way is a combination of redeeming active codes and grinding Story Mode stages. Replaying the later chapters of Story Mode provides the highest Gem-per-minute ratio for solo players.
Q: Can I get every unit without spending Robux?
Yes. Universal Tower Defense Z is designed to be F2P friendly. By participating in Events, Raids, and using Codes, you can acquire every unit in the game, though it will require significant grinding for Evolution materials.
Q: What should I do with duplicate units?
Duplicate units can often be used as fodder for Evolution or sold for a small amount of currency. In some cases, having multiple copies of a support unit is beneficial for different team compositions.
To master Universal Tower Defense Z in 2026, stay active in the community to catch new Codes, prioritize your Evolution materials for S+ Tier units like Jinoo and Joyful Captain, and never spend your Ruler Tickets on low-tier banners. With a disciplined farming routine, your roster will soon dominate every mode from Story to World Raids.
