Ultra Jack Bangboo Guide: Skills, Best Teams and How to Get It - Zenless Zone Zero

Ultra Jack is an S-Rank Fire Combat Bangboo introduced in Zenless Zone Zero Version 3.0, the Roscaelifer-themed update that expanded the game's Bangboo roster with new high-tier options. As a member of the Roscaelifer faction itself, Ultra Jack brings a unique combination of sustained aerial Fire damage, team-wide Energy regeneration, and massive burst damage through its Chain Attack. With a T0 rating on community tier lists, it represents one of the strongest Bangboo investments currently available for players building around the Roscaelifer faction.

Ultra Jack Base Stats

Ultra Jack's base stats at level 1 start at 396 HP, 72 ATK, 103 Impact, and 28 DEF. At maximum level 60, these scale to 4,210 HP, 8,863 ATK, 103 Impact, and 666 DEF. The Impact stat remains fixed across all levels, while ATK scales dramatically to become Ultra Jack's defining offensive attribute. These stats place Ultra Jack among the highest-damage Bangboos in the game, with its ATK at level 60 exceeding most other S-Rank options.

Skill Breakdown

Ultra Jack's Active Skill, Ultra Firepower Suppression, activates a flying state where Ultra Jack hovers above the battlefield and continuously fires at a targeted enemy. Each shot deals Fire DMG and accumulates Fire Anomaly Buildup, making it effective for triggering the Burn anomaly in Fire-based teams. The sustained nature of this skill provides consistent damage application over its duration rather than a single burst, allowing it to chip away at enemy HP while building toward the next anomaly trigger. The flying state also grants Ultra Jack a degree of positional safety, keeping it elevated above many ground-based enemy attacks.

The Extra Ability, Ultra Boost Module, is Ultra Jack's defining passive and requires at least one Roscaelifer faction character to be present in the active team. When any team member triggers a Vortex effect or uses a Chain Attack, all team members receive 2 Energy and Ultra Jack's Active Skill DMG increases by 25% for 45 seconds. This effect has a 30-second cooldown between activations. The 2 Energy regeneration applies universally, making it valuable for teams that rely on frequent Ultimate usage. In Roscaelifer teams that naturally generate Vortex and Chain Attack opportunities, this passive provides near-constant uptime on both the Energy regeneration and the damage boost.

The Chain Attack, Super Ultra Cannon, fires a fully charged hand cannon that deals massive Fire DMG to all enemies within its area of effect and accumulates significant Fire Anomaly Buildup. This skill functions as Ultra Jack's burst damage window and can be triggered during standard Chain Attack sequences alongside player-controlled Agent Chain Attacks. The combination of its Active Skill for sustained pressure and its Chain Attack for burst makes Ultra Jack a versatile offensive Bangboo that contributes damage throughout the entire combat cycle.

Best Team Compositions

Ultra Jack's team building revolves entirely around the Roscaelifer faction requirement for its Extra Ability. Without at least one Roscaelifer character on the team, Ultra Jack operates at significantly reduced effectiveness, making faction synergy non-negotiable for optimal performance.

The premier team composition pairs Ultra Jack with Velina as the Main DPS, a Wind Anomaly character and fellow Roscaelifer member introduced in Version 3.0. Yuzuha fills the Support role, accelerating Anomaly Buildup for the entire team with her Physical Support kit. Promeia serves as the Sub-DPS, an Ice Anomaly character who triggers Ice Vortex effects that create Bloom reactions, simultaneously activating both Velina's Wind Anomaly synergies and Ultra Jack's Extra Ability Energy regeneration. This composition generates frequent Vortex and Chain Attack triggers, keeping Ultra Jack's 25% damage boost active with minimal downtime.

The Chain Attack team offers an alternative composition centered around Norma, an upcoming Fire Stun character and another Roscaelifer member. Norma's Stun role creates frequent stagger windows that chain into Chain Attacks, activating Ultra Jack's Extra Ability consistently. Astra provides Ether Support buffs for the team, while Evelyn contributes as a Fire Attack Main DPS. This composition leans into Fire element stacking while leveraging the Roscaelifer faction requirement through Norma, and the Chain Attack focus aligns perfectly with Ultra Jack's passive trigger conditions.

Players who lack Velina or Norma should prioritize pulling at least one Roscaelifer character before investing heavily in Ultra Jack, as the Bangboo's performance without its Extra Ability falls significantly behind other S-Rank alternatives that have less restrictive passive requirements.

How to Get Ultra Jack

Ultra Jack is obtained exclusively through the Bangboo Channel in Signal Search, which uses Boopons as its dedicated currency. A single pull costs 1 Boopon and a 10-pull costs 10 Boopons. The Bangboo Channel operates with an 80-pull S-Rank pity system that is entirely independent from Agent and W-Engine channels, meaning progress on those banners does not affect Bangboo pulls and vice versa.

Version 3.0 introduces a selectable S-Rank guarantee for the Bangboo Channel, allowing players to choose a specific S-Rank Bangboo as their target before pulling. When an S-Rank pull occurs, it is guaranteed to be the selected target rather than a random S-Rank from the pool. Players can freely switch their selected target at any time without resetting their pity count. This eliminates the randomness that previously made acquiring specific S-Rank Bangboos unreliable, making Ultra Jack a deterministic investment for players willing to save Boopons until hitting the 80-pull pity.

Boopons are earned through several in-game sources. Hollow Zero provides Boopons as completion rewards across its various difficulty levels. Rally Commissions offer Boopons as mission completion rewards. The Bangbuck Exchange allows exchanging accumulated Bangbucks for Boopons. Limited-time events frequently distribute Boopons as event rewards. Players who consistently clear weekly Hollow Zero content and participate in events can accumulate enough Boopons for an S-Rank pull across approximately two patch cycles without spending premium currency.

Building up your Boopon reserves and securing Ultra Jack before its focused availability period ends requires consistent resource management. Whether you need Polychromes to pull for Roscaelifer characters like Velina or Norma to activate Ultra Jack's Extra Ability, or Monochrome to convert into Boopons for the Bangboo Channel, Topuplist offers fast and reliable top-up services. Visit the Zenless Zone Zero top-up page to grab the currency you need and pair Ultra Jack with its ideal Roscaelifer teammates.

Upgrade Materials and Costs

Leveling Ultra Jack from 1 to 60 requires a total of 500,000 Denny, 4 Ether Electrolyte, 30 Concentrated Cooling Fluid, and 32 Energy Transfer Fluid. The material costs are distributed across five breakpoint thresholds, with the largest single investment at the level 50 to 60 range requiring 250,000 Denny and 20 Concentrated Cooling Fluid.

The level 10 to 20 breakthrough costs 15,000 Denny and 4 Ether Electrolyte. The 20 to 30 range requires 35,000 Denny and 12 Energy Transfer Fluid. Levels 30 to 40 consume 75,000 Denny and 20 Energy Transfer Fluid. The 40 to 50 bracket demands 125,000 Denny and 10 Concentrated Cooling Fluid. The final push from 50 to 60 uses 250,000 Denny and 20 Concentrated Cooling Fluid. Ether Electrolyte is the rarest material, needed only for the initial breakthrough and obtained primarily from high-level Hollow Zero clears and event shops. Energy Transfer Fluid and Concentrated Cooling Fluid are farmed from Hollow Zero stages at corresponding difficulty levels, with higher difficulties providing better drop rates.

Should You Pull for Ultra Jack?

Ultra Jack is a strong investment for players who own or plan to acquire Roscaelifer faction characters. The Energy regeneration on its Extra Ability provides consistent value across long fights, and the 25% Active Skill DMG increase with 45-second uptime against a 30-second cooldown ensures near-permanent uptime in teams that trigger Vortex or Chain Attacks frequently. The T0 rating reflects its performance ceiling when fully enabled, not its baseline effectiveness.

For players without Roscaelifer characters, Ultra Jack loses its Extra Ability entirely, operating at a fraction of its potential. In this state, other S-Rank Bangboos with less restrictive passives may provide more consistent value. Players should plan to pull a Roscaelifer character either before or alongside Ultra Jack to avoid underutilizing the investment.

The new selectable guarantee system removes the risk of pulling unwanted S-Rank Bangboos, making Ultra Jack a safe target for players who have saved enough Boopons to reach the 80-pull pity. This system also benefits free-to-play players who want to guarantee a specific S-Rank Bangboo without relying on random pulls. Players with fewer than 80 Boopons can still pull but should be aware that hitting Ultra Jack before the pity threshold relies on early luck rather than guaranteed rates.

Comparison to Other S-Rank Bangboos

Ultra Jack differentiates itself from other S-Rank Bangboos through its faction-locked Extra Ability and Energy regeneration utility. While most S-Rank Bangboos provide damage amplification or anomaly buildup without faction restrictions, Ultra Jack trades universal applicability for higher peak performance within Roscaelifer teams. This makes it a specialized pick rather than a generalist option, best suited for players who have committed to building Roscaelifer teams as their primary composition.

The shift from random S-Rank pulls to the selectable guarantee system also increases Ultra Jack's relative value compared to older S-Rank Bangboos that players may have obtained randomly. Players who previously avoided the Bangboo Channel due to its unpredictable S-Rank distribution can now target Ultra Jack with confidence, making it one of the most accessible S-Rank Bangboos for players who plan their pulls around the new guarantee mechanic.

Ultra Jack's Fire element places it in a competitive space alongside other Fire Bangboos, but its unique combination of sustained aerial damage, team Energy support, and selectable guarantee acquisition gives it a distinct role that no other Fire Bangboo currently fills. For Roscaelifer team players, it is the clear best-in-slot choice and a worthwhile investment for both current and future content.
