Why These Are Currently the Universal Tower Defense Z Best Units
The massive July 2026 update for Universal Tower Defense Z completely reshuffled the meta. Four new Boundless units, nine Secrets, two Exclusives, eight Mythics, and the game-breaking Godly “Grammy” have all landed. If you want to know the universal tower defense z best units right now, you need to focus on the Extraction event rewards, the new Balance evolutions, and a handful of reroll-friendly picks. Early-game staples like Kimpachi and Fern are still available through permanent codes, but the endgame power gap has widened dramatically.
Below we break down every top-tier unit you should target, a full tier list for DPS, crowd control, and shield-breaking, plus proven farming routes for rerolls, gems, and Universal Fragments.
Early Game Powerhouses – Beginner Codes and Easy Raids
The developers made Kimpachi and Fern permanent beginner codes, and for good reason. Kimpachi (Berserker) is one of the strongest early-game shield-breaker hybrids in the entire game. His real potential unlocks when you farm the legend stage “Hollow Moon Act 3.” There you have a 5% chance to obtain the Berserker Cleaver – a Vanguard Familiar that boosts his damage by roughly 800%. Once you have that item, Kimpachi shreds through wave content that would normally require much rarer units.
Fern is the second guaranteed code. She’s a top-tier support that provides consistent utility, and you can keep her in your lineup even after you transition to harder content. Both units will comfortably carry you through story mode and into the first raid.
| Unit | How to Get | Strengths | Best With |
|---|---|---|---|
| Kimpachi (Berserker) | Permanent beginner code | Shield-breaker, hybrid DPS, 800% damage buff with cleaver | Vanguard Familiar (farmed from Hollow Moon Legend Act 3) |
| Fern | Permanent beginner code | Meta support, solid utility | Any DPS carry |
Once you’ve cleared early stages, your next goal is the Ichigo raid. This is the simplest raid in the game and gives you a 10% chance (Boss Rush) or 3% chance (Act 5) to receive Ichigo. Ichigo’s new Balance evolution, Ichigo Rage, is one of the best cost-to-power ratios in the current meta. The evolution materials are easy to obtain: buy a Hollow Essence from the Hollow Shop and farm three swords from the new (harder) raid with matchmaking. The result is a powerhouse that can hold its own even in late-game setups.
Extraction Event Units – The Most Broken Synchros in the Game
If you have the means to complete the Extraction game mode, you can obtain the three Spider-Man‑derived units that community reports currently consider the strongest in Universal Tower Defense Z. These units – Spider-Man, Symbiot Spider-Man, and a third Extraction reward – all have Synchro abilities that activate when you max out specific pairings.
For example, maxing Iron Man and standard Spider-Man gives you Iron Spider, a cone AoE hybrid that deals over a million raw damage. Maxing Venom and Spider-Man creates a different hybrid that stacks bleed and burn for even more sustained damage. The three units together achieve damage numbers that exceed one million per hit with critical rates that make other DPS options look tame.
| Unit | Role | Damage Output | Synchro Pairing |
|---|---|---|---|
| Spider-Man (Extraction) | Hybrid DPS | 1M+ with crit | Iron Man → Iron Spider |
| Symbiot Spider-Man (Extraction) | Hybrid DPS (Bleed/Burn) | 1M+ stacking | Venom → Hybrid AoE |
| Third Extraction Unit | Support / Utility | Variable | Completes trinity |
The best part? You can grind the Extraction mode in a few hours to get all three units. The game mode itself is easier than most players expect, especially if you team up with others. Each completion also rewards 40 rerolls, making it a dual-purpose farm.
Godly and Mythic Tier – What to Pull for This Update
The banner update introduced only one truly must-have Godly: Grammy (the unrivaled unit). She is available on both banners and completely warps the meta around her 50% all‑stats buff for Bleach units. If you can acquire her, she elevates every relevant Bleach unit (Ichigo, Rukia, Yamamoto) to new heights.
The new Mythics on the banner are mostly mediocre according to experienced players. The one exception is Rukia (sometimes called “Ruka”). She is relatively easy to obtain and evolve – her evolution path mirrors Ichigo’s – and after evolution she becomes a full AoE slow/freeze unit that deals around 400k damage per tick. That’s without Grammy’s buff.
| Unit | Rarity | Role | Verdict |
|---|---|---|---|
| Grammy | Godly (Unrivaled) | Meta buffer / DPS | Must-have; 50% Bleach buff |
| Rukia | Mythic | AoE slow/freeze (400k DPS) | Best new Mythic; easy to evolve |
| Yuhoba | Boundless | Decent but outclassed | Skip unless you need filler |
| Yamamoto | Mythic | Decent DPS (with Bleach synergy) | Viable only with Grammy |
| Summer Capsule Units | Various | Underwhelming | Community recommends skipping |
Joker from the Extraction‑like game mode is also excellent, but that game mode is more difficult and time‑consuming than the Spider‑Man event. Dedicated farmers can still solo it using guides, but the Spider‑Man trio is more accessible.
Full Tier List – DPS, Crowd Control, and Shield-Break
Based on the latest meta (July 2026), here is the consolidated tier list for Universal Tower Defense Z, drawing from both the YouTube guide and the community‑maintained wiki.
Meta DPS Units
| Unit | Tier | Notes |
|---|---|---|
| Grammy (Unrivaled) | S+ | Godly buff, top damage |
| Spider‑Man Trio (Extraction) | S | Synchro combos > 1M DPS |
| Ichigo (Rage) | S | Easy farm, high payoff |
| Ultimate Fused Warrior | A | Strong, but requires heavy investment |
| King Sailor (Unrivaled) | A | Good alternative if you missed Extraction |
| Angel Born in Hell (Unrivaled) | A | Niche uses, outclassed by Grammy |
Meta Crowd Control (CC) Units
| Unit | Tier | Effect |
|---|---|---|
| Ancient Shinobi (Reawakened) | S | Combines with Nutaru for Unparalleled Armor Synchro |
| The Strongest of Today | S | Freeze + high damage |
| Rukia (Evolved) | S | Full AoE slow/freeze |
| Quake Warlord (Destroyer) | A | Knockback and stun |
| Prodigy Mage (Apprentice) | A | Shield‑break + slow |
Shield-Break Specialists
| Unit | Tier | Efficiency |
|---|---|---|
| Kimpachi (Berserker) + Cleaver | S | Early game beast, unlocks on day one |
| Alpha Devil (Omega) | A | High shield damage, rare |
| The Drink (Super Rage) | A | Solid niche option |
| Ancient Mage (Sage) | B | Reliable but outclassed |
How to Farm Rerolls, Gems, and Universal Fragments
To reroll for the best traits on your top units, you need rerolls (often called “rules”). The guide outlines a weekly rotation that can net you around 2,500 rerolls per week if you are efficient.
| Method | Rerolls Per Week | Notes |
|---|---|---|
| Raids (6 per week) | 600 (100 each) | Granotica Raid is most efficient for both gems and Universal Fragments |
| Ultra Boss Shop | 1,500 | Three bosses: 100 + 200 + 200 |
| Featured Challenges | 1,100 (220×5) | 65 rerolls daily per challenge, three challenges per day |
| Extraction Mode | Varies (~40 per run) | Spider‑Man extraction is 15 min per run |
| Event Shops & Codes | 200+ | Codes from the update can give up to 200 instantly |
Gems and Universal Fragments (both types) drop from virtually every stage, but the fastest way is to AFK‑farm Granotica Raid. Gold is abundant from selling unwanted units.
Frequently Asked Questions
What are the universal tower defense z best units for a beginner?
Start with the permanent code units Kimpachi and Fern. Then farm the Ichigo Raid to obtain Ichigo and evolve him to Ichigo Rage. These three will carry you through early and mid‑game content without needing Godly pulls.
Are the Extraction units really that strong?
Yes. Community reports consistently show the Spider‑Man trio dealing over one million damage per hit once their Synchros are activated. They are currently considered the strongest non‑Godly units in the game and can be farmed in a single afternoon.
How many rerolls can I get per week?
If you complete all raids, Ultra Boss fights, featured challenges, and a few Extraction runs, you can earn approximately 2,500 rerolls weekly. Codes and events add extra.
Do I need to pull Grammy to be competitive?
Grammy is extremely strong and provides a massive 50% buff to Bleach units, but you can build a top‑tier team without her using the Extraction units and Ichigo. She is a luxury for those who want the absolute highest ceiling.
