What Are Uniparts?

Kaiju No. 8 Uniparts

Uniparts are enhancement parts that can be equipped on characters to increase their stats and, in certain cases, grant additional abilities through Set Effects. They are a core progression system designed to let players customize characters for different roles such as damage dealers, tanks, or support units.

Each Unipart provides specific stat bonuses depending on its type, rarity, and development outcome. Choosing the right Uniparts is essential to fully optimize a character’s performance in both PvE and PvP content.

Unipart Types

  • Arms: Typically focused on offensive stats such as Attack, Critical Rate, or Skill Damage.
  • Body: Usually grants defensive or survivability stats such as HP, Defense, or Damage Reduction.
  • Legs: Often provides utility-focused stats like Speed, Evasion, or Gauge Gain.

When developing Uniparts, you can choose which part type to create, allowing you to target the stats your character needs most.

Not all characters are able to use Uniparts. Some special characters are excluded from this system, including: Kaiju No. 8 Kafka Hibino. These characters are usually balanced around unique skills, exclusive mechanics, or higher base stats, meaning they are designed to perform effectively without relying on Uniparts.

Developing Uniparts

Kaiju No. 8 Uniparts

Uniparts can be developed directly from the Character Equipment Screen. To do so:

  1. Select the Unipart type you want to create (Arms, Body, or Legs).
  2. Choose the appropriate Unimaterials required for development.
  3. Complete the development process to obtain a Unipart with randomized stats based on its type.

Because the resulting stats can vary, developing Uniparts is both a strategic and resource-management decision.

Keep or Overwrite Existing Uniparts

If a character already has a Unipart equipped in the selected slot, the game gives you a choice after development:

  • Keep the currently equipped Unipart.
  • Overwrite it with the newly developed Unipart.

This system allows you to compare stats before committing, ensuring you only equip Uniparts that improve your build.

How to Obtain Unimaterials

  • Unimaterials, the resources required to develop Uniparts, can be obtained through Training stages.
  • The Training stage you need to challenge depends on the Unipart set you want to create.
  • It’s recommended to decide which Unipart or Set Effect you are aiming for before farming materials, to avoid wasting resources.
  • Efficient material planning is key to building strong and flexible Unipart setups.
Uniparts Are Character-Bound Uniparts Cannot Be Swapped Once a Unipart is equipped on a character, it becomes permanently bound: Equipped Uniparts cannot be removed or transferred to another character. When developing a new Unipart, the one you choose not to equip is discarded. This makes Unipart development a high-commitment decision, especially at higher rarities.

Uniparts Rolls

Kaiju No. 8 Uniparts

Even among Uniparts of the same rarity, stat values can vary due to random rolls. To make optimization easier, the game highlights high stat rolls in orange. Because of this system, long-term progression usually focuses on farming 5-star (Gold) Uniparts with optimal orange stats, as these provide the highest possible performance ceiling.

Available Stats by Unipart Type

Each Unipart type has a fixed pool of possible stats, meaning you can target specific builds by choosing the correct part.

Type Stat Pool Role Focus
Arms HP (Flat, %)
ATK (Flat, %)
DEF (Flat, %)
Raw survivability or damage scaling
Body CRIT Rate
CRIT DMG
Healing Multiplier
Ultimate Gauge Charge Rate
Effect Hit Rate
DPS optimization, healing, debuff support
Legs Elemental DMG Dealt
SPD (Speed)
Effect RES
Turn order control and resist utility

Unipart Set Effects

Uniparts feature Set Effects that activate when you equip matching Uniparts in all three slots (Arms, Body, and Legs).

  • There is no benefit to mixing different Unipart sets.
  • To activate and maximize a Set Effect, all equipped Uniparts must belong to the same set.
