Universal Tower Defense Z Gremmy Build Guide: Best Setup & Team Synergies

Creating the Ultimate Universal Tower Defense Z Gremmy Build

Setting up a powerful Universal Tower Defense Z gremmy build is one of the most effective ways to conquer high-tier raids and late-game content. The Visionary unit, heavily inspired by Gremmy Thoumeaux from Bleach: Thousand-Year Blood War, offers unparalleled field control through clone generation and status debuffs. To unlock his full potential, players must optimize their Universal Tower Defense Z gremmy build by choosing the right traits, pairing him with synergistic units, and mastering his active abilities.

In his final Unrivaled form, Gremmy (known in-game as Visionary) becomes a cornerstone for high-DPS teams. Because his mechanics scale dynamically based on the units surrounding him, throwing him into a random lineup will severely limit his capabilities. This comprehensive wiki-style guide breaks down the math, mechanics, and strategies required to build the ultimate team around this top-tier unit.

Core Mechanics of Visionary (Gremmy)

To make the most of your Universal Tower Defense Z gremmy build, you must understand how Gremmy's Unrivaled form behaves on the battlefield. Gremmy has a base spawn cost of 1,700 Yen and possesses permanent immunity to Stun. His kit is divided into highly synergistic passives that reward tactical placement and precise timing.

Intangibility and Debuff Management

Gremmy is completely immune to stun effects. His presence also acts as a clean-up utility for your other damage dealers. When an enemy attempts to apply a debuff to any "Peroxide" Tag unit within Gremmy's range, the duration of that debuff is immediately slashed by 50%.

Furthermore, every time an enemy attempts to debuff an allied Peroxide unit in his range, Gremmy instantly spawns an Imagination Clone (provided he hasn't reached his clone limit). This makes him an exceptional counter to bosses that rely heavily on disabling your towers.

The Power of Imagination Clones

Gremmy's primary source of damage and crowd control comes from his clones. Understanding how these clones scale is the secret to maximizing your Universal Tower Defense Z gremmy build:

• Spawn Rate: Gremmy spawns a clone on every other attack, up to a maximum cap of 3 active clones at any given time.
• Clone Stats: Clones inherit 50% of Gremmy's current Damage and Range. Crucially, clones have a locked SPA (Seconds Per Attack) of 7.
• Duration: Clones naturally despawn after 20 seconds. However, if a "Peroxide" Tag unit is placed within Gremmy's range, the clone duration is increased by 10 seconds, keeping them on the map for a total of 30 seconds.
• Self-Buffs: For every active clone on the field, Gremmy gains a -5% SPA reduction and a +20% Damage increase. At his maximum cap of 3 clones, Gremmy enjoys a -15% SPA reduction and a +60% Damage boost.
• On-Death Crowd Control: When a clone's timer expires and it disappears, it automatically applies a 3-second Stun to all enemies within that clone's attack range.

Fragile Reality

This passive makes Gremmy a premier shield-breaker. For every eight shielded enemies that enter Gremmy's range, he completely strips their shields for 5 seconds. Additionally, when Gremmy lands a Critical Hit on an enemy suffering from an alteration (such as Bleed or Suffocation), he instantly deals an extra 75% Damage. This effect has a 20-second cooldown but can chunk boss health pools significantly.

The Best Trait for Gremmy

Selecting the correct trait is a make-or-break decision to finalize your Universal Tower Defense Z gremmy build.

• The Absolute Best Trait: Ruler

Why Ruler Outperforms Other Traits

Because Gremmy's clones copy 50% of his raw Damage and Range, any trait that provides flat, massive boosts to these two specific stats will scale your clones exponentially. Furthermore, since Gremmy's clones have a locked SPA of 7, traits that heavily favor attack speed over raw damage lose a significant portion of their value when applied to his summons. The Ruler trait provides the perfect stat profile to ensure both Gremmy and his three clones deal maximum damage over the largest possible area of the track.

Materialization Arsenal: Active Ability Strategy

Gremmy's active ability, Materialization Arsenal, allows players to manually change his attack type mid-battle. When you first place Gremmy down, his default attack is Spiritual Steel.

To get the most out of your Universal Tower Defense Z gremmy build, you must cycle through his forms depending on the current wave composition and enemy types:

Attack Type Breakdown

Tactical Application

For general wave clearing, Galaxy Void is the undisputed best form. Converting Gremmy to a Hybrid unit allows his clones to target flying enemies, which is essential in late-game maps. The 30% Slow provides excellent stalling utility, and the Suffocation damage ticks constantly prime enemies to trigger Gremmy's Fragile Reality passive, resulting in massive 75% instant damage critical hits.

Save Colossal Meteor strictly for isolated bosses at choke points where the temporary -50% Range penalty won't cause fast enemies to slip past your defense.

Team Synergies and Unrivaled Buffs

Gremmy is a team player who offers massive passive stat boosts to specific tags and elements. To run a highly competitive Universal Tower Defense Z gremmy build, you must construct your deck to exploit these Unrivaled Buffs.

Passive Buffs Provided by Gremmy (Unrivaled)

When Gremmy is active on the field, he grants passive stat increases to all units within his range that carry the following Tags or Elements:

• For Tag "Peroxide": +50% Damage and +10% Critical Rate.
• For Tag "Summoner": +35% Damage and -7.5% SPA.
• For Element "Rose": +20% Damage and +15% Critical Damage.

Recommended Teammates

To maximize these buffs and ensure Gremmy's clones remain active for the extended 30-second duration, always run him alongside:

1. The Almighty King (Peroxide Tag): Benefits directly from Gremmy's massive +50% Damage buff while easily keeping Gremmy's clone duration extended.
2. Moonless Sky (Peroxide Tag): Another top-tier DPS unit that thrives when placed within Gremmy's range, shredding enemies with boosted critical rates.
3. High-tier Summoner Units: Any unit with the Summoner tag will receive the -7.5% SPA reduction, allowing you to flood the path with extra defensive units.

How to Obtain and Evolve Gremmy (Visionary)

Before you can run a complete Universal Tower Defense Z gremmy build, you must obtain the base unit and collect the necessary fragments to fully evolve him to his Unrivaled state. Plan the summon and evolution grind as part of the build, since his clone scaling and final team role depend on reaching the evolved form first.

Step 1: Summoning Visionary

Visionary is an Unrivaled-rarity unit that can be pulled from either the Basic Banner or the Selection Banner.

• Cost: 50 Gems per single summon.
• Summon Chance: 0.05%. There is no pity meter for Unrivaled units, meaning you must rely purely on luck to pull him.

Step 2: Evolving to Visionary (Inspired)

Once you have secured the base unit, you must complete his first evolution. Navigate to the Evolutions menu and submit the following materials:

Note: Fragments can be obtained by clearing Challenges and specific Acts in the Legend Stage. They can also be purchased directly from the Merchant or the Virtual Merchant.

Step 3: Evolving to Visionary (Unrivaled)

To reach his final form and unlock the clone-scaling passives required for the build, you must collect four unique Unrivaled Fragments and 25,000 Gold:

• Unrivaled Fragment 1: Drops from Act 3 of the Beast Desert Legend Stage.
• Unrivaled Fragment 2: Obtained by completing the Moonless Sky Rift in Universal Tear mode.
• Unrivaled Fragment 3: Purchased from the Reaper City Raid Shop or rewarded for clearing the Reaper City Boss Rush level.
• Unrivaled Fragment 4: Obtained by participating in the Hollow Destroyers vs Reapers event mode.
