Best Nikkes
Red Hood B3: One of the best Pierce DPS. She easily outdamages Rapi: Red Hood due to piercing core and both parts. She is also manual-friendly and does not need expensive OL to perform. 
Rapi: Red Hood: One of the best Fire DPS. Despite being a Fire Nikke, she enjoys elemental advantage against Iron-weak enemies. She can be used as a Burst 1 CDR or Burst 3 DPS depending on the team. 
Crown: The best general Burst 2 Nikke. She provides a shield that allows you to block stunning slams and poison spits from Ultra. She is almost irreplaceable in the AI Ultra fight. 
Anis: Star: The best general Burst 1 CDR. She helps with breaking parts if your team struggles to. She also provides burst gen. 
Milk: Blooming Bunny: One of the best Pierce DPS. However, she requires proper manual, investment and reload or ammo support from the team. 
Mast: Romantic Maid: One of the best general flex. However, bursting Maid Mast costs you one burst of Crown shield. 
Siren: Great Burst 1 CDR. She does decent damage output while offering burst gen to the team. She also provides ammo support for Rapi: Red Hood and Milk: Blooming Bunny. Use Siren if you do not have Anis: Star. 
Raven : Great Iron DPS against Ultra due to not abusing the Pierce environment. She, being a collab unit, is not obtainable anymore (unless rerun). Her attack animation also causes a slight trouble when she needs to cover. She can be used as Burst 3 DPS or off-burst. 
Privaty (Treasure): One of the best general flex. 
Naga : The best Crown’s flex against enemies with a high-uptime core. She provides core damage buff and great passive healing. 
Helm (Treasure): Decent neutral DPS or flex. She offers burst gen, buff and increases Crown S2 uptime. When used as neutral DPS, she also offers lifesteal healing for the team. 
Snow White: Heavy Arms: Great neutral DPS. Since she is built universally, she can fill your Ultra team until you get a proper Ultra team. She also offers burst gen. 
Snow White: One of the best Pierce DPS. She abuses even a fragile and temporary/low-up-time multiple parts scenario heavily. However, she requires proper manual play, timing, investment and also rather niche supports to perform. Commonly paired with Miranda (Treasure) or Zwei (Treasure). 
Miranda (Treasure): Burst 1 buffer for Snow White hypercarry. 
Zwei (Treasure): Burst 1 buffer for Snow White hypercarry. 
Helm: Aquamarine: Great support CDR for iron-weak contents only. While her CDR value is rather low, her damage taken debuff against Iron-weak enemies outperforms most of the other CDR choices. Commonly used as flex and paired with Miranda (Treasure) or Zwei (Treasure). 
Eve : Decent Iron DPS. She, being a collab unit, is not obtainable anymore (unless rerun). While her damage is rather mediocre, she provides a damage taken debuff against Iron-weak enemies. 
Laplace (Treasure): Great Iron DPS against enemies with parts. She can be like a slightly weaker Red Hood that cannot cover during her burst. 
Maxwell: Decent Iron pierce DPS. She abuses multiple parts scenario like Snow White but much weaker. She also provides a great atk buff for 2 allies with the highest atk. 
Tia : The second-best shielder, right after Crown. She provides a shield that allows you to block stunning slams and poison spits from Ultra. However, she is Burst 1 re-enter Nikke, so an extra Burst 1 CDR Nikke is required for the team.
Best Teams
Here are some example teams you can try:
Pierce Heaven Mode: Anomaly - Ultra || Element: Iron When using Red Hood, save her B1 to be used with her B3 and Maid Mast’s Burst at 3 stacks once a fight. Anis: Star may be replaced with Little Mermaid or Rapi: Red Hood or Liter. Cinderella vs Ultra Mode: Anomaly - Ultra || Element: Iron Cinderella just keeps winning and replaces Rapi: Red Hood in her funneling team. Anis: Star may be replaced with Little Mermaid or Rapi: Red Hood. Characters
About the team
Burst Maid Mast every third burst (Crown → Crown → Mast). However, there will be situations where you need Crown to go third instead for her shield. When that happens, Burst Maid Mast at 2 stacks instead (Crown → Mast → Crown).Substitutions
Red Hood or Cinderella: Crystal Wave may be replaced with Rapi: Red Hood, Milk: Blooming Bunny, Laplace (Treasure), or Raven.
Mast: Romantic Maid may be replaced with Naga or Privaty (Treasure) or Helm (Treasure) or Helm: Aquamarine.Characters
About the team
Switch Cinderella: Crystal Wave to Sniper mode for phase 1, and MG mode for phase 2.
Burst Maid Mast with Cinderella as much as possible. However, there will be situations where you need Crown burst for her shield. Substitutions
Cinderella: Crystal Wave may be replaced with Rapi: Red Hood.
Helm (Treasure) may be replaced with Snow White: Heavy Arms.
Artillery vs Moth Mode: Anomaly - Ultra || Element: Iron A high investment, high reward team. Snow White needs highest final ATK than the rest of the team to make sure she gets Miranda (Treasure)’s Critical Rate buff. Zwei (Treasure) may be replaced by Miranda (Treasure). Battle without your King Mode: Anomaly - Ultra || Element: Iron A shielder is needed to survive the fight, which is the only reason Tia is here. Tia needs to Burst to apply shields and requires a second B1 Nikke for the team to function. Anis: Star may be replaced with any B1 CDR. Characters
About the team
Make sure every Snow White nuke hits the core and 2 parts. Substitutions
Maxwell may be replaced with Rapi: Red Hood or Cinderella: Crystal Wave if and only if Snow White still manages to get Miranda (Treasure)’s S2 Critical Rate buff.Characters
About the team
Since Tia is Iron, you pretty much get the freedom of running whatever you’ve invested in, hence very beginner friendly.
Burst Tia to block the slam or shockwave from Ultra. Substitutions
Naga may be replaced with Nayuta or Grave.
Boss Fight Breakdown
Ultra is a light boss, although it has weird quirks related to its core. For a quick TL;DR:
Ultra has 1 core and 2 parts; Pierce DPS Nikkes will utilize them well.
Bring an Iron Code Nikke or Rapi: Red Hood for QTE (red circles).
Make sure you have some sort of shield to survive the shockwave(s).
Cover from the poison or use a powerful shield to tank it.
Core can respawn multiple times if certain conditions are met:
For the 1st respawn, reach Stage 3 and destroy the core before the first shockwave; if you reach Stage 4, you get a tankier core.
For the 2nd respawn, reach Stage 6 and destroy the core before the second shockwave; really hard to do unless you respawn a tankier core at the beginning.
For the 3rd respawn, reach Stage 8 and destroy the core.
If you are looking for the full breakdown, Ultra’s stats increase a lot in certain stages; at Stage 4, ATK and DEF increase massively (the DEF increase is so high that it can result in lower-sync players dealing 1 damage). After that, at Stage 5, ATK increases slightly. Starting from Stage 6, ATK will rise by a massive amount every Stage, capping at Stage 8. DEF increases slightly at Stages 7 and 8.
Ultra deals increased damage to Water Nikkes:
300% at Stages 1~3
400% at Stages 4~6
500% at Stages 7~9
Phase I
Ultra has:
A core under a shell; only pierce units can hit it.
2 Poison chambers; they do absolutely nothing and can be hit by manually aiming for them or having a Nikke with pierce shoot the core, hitting both parts at the same time.
At the beginning, Ultra will fire guns at the highest attack Nikke in the team. There will be a warning sign on the aimed target before guns are fired. This attack can be covered from or taunted.
After the gun attack, Ultra will obtain an elemental shield and spawn the first QTE (red circles) of the fight, only Iron Nikkes and Rapi: Red Hood can do damage through this shield. Failing to destroy QTE in time results in an attack that wipes 2~3 Nikkes on your team. Successfully destroying the QTE on time results in Ultra getting stunned for a short duration and the shield being dispelled.
After that, Ultra charges its first shockwave of the fight. Shortly after, it will shockwave the ground, dealing damage to all Nikkes while stunning them. Can take cover from the attack or use a shield (mainly Crown’s or Tia’s Burst) to block the attack entirely.
If the core was destroyed, a few things can happen:
Didn’t reach Stage 4 before respawn time (2:34): Core respawns with low Max HP.
Reached Stage 4 before respawn time (2:34): Core respawns with higher Max HP.
Reached Stage 4 before shockwave starts charging: Core immediately respawns at Full HP before charging shockwave.
It is possible to stall the QTE awhile to do more damage before the respawn time.
Right after the shockwave, Ultra spits a poison attack on the entire team that applies DoT (damage-over-time) to Nikkes hit by the attack. Can be blocked by covering or by using a really strong shield to tank it (mainly Crown’s or Tia’s Burst). DoT won't apply through the shield.
If any Poison chambers were destroyed, they respawn after the attack.
Rest of Phase 1 will repeat these same actions but in a different order: Guns (at the highest ATK Nikke) → QTE → QTE → Guns (at highest ATK Nikke) → QTE → QTE → Poison chamber respawn → QTE → Stun → Core respawn (if core is destroyed and Stage 6 is reached before shockwave charge) → Shockwave → Poison Spit.
Interim
After the Poison Spit attack, Ultra removes its outer shell, exposing the core for all Nikkes to hit. Then, it'll respawn any destroyed Poison chambers right before entering a Special QTE (red and grey circles). Failing to destroy red circles in time or destroying any grey circles results in a squad wipe.
The circles spawn with a fixed pattern a total of 2 times. The first time, it will be centered, then the 2nd time, it will be at a slightly different location on the screen. Successfully destroying the QTE (red circles) leads to Phase 2.
Be careful where you pre-aim, as the grey circles can spawn where you are aiming your crosshair.
Phase 2
Ultra's core, if alive, is now permanently exposed to all Nikkes for the rest of the fight.
After successfully destroying the previous QTE (red circles), the boss will be stunned for a short time. After that, if any Poison chambers are not destroyed, it'll proceed to shoot a bunch of purple balls; these apply DoT (damage-over-time) on any Nikke they land on, but can be i-framed or blocked by cover. If Poison Chambers were destroyed in time, Ultra will literally AFK instead.
Next, it'll respawn the Poison Chambers before proceeding with another Shockwave and Poison Spit (at Stage 8, Crown’s shield alone won't be enough to block the poison, so you will need to cover towards the end of the Spit). If you destroy the current core before reaching Stage 8, it will respawn the core after reaching Stage 8.
The rest of the fight will be repeating this pattern one more time, then another Special QTE.
Tips
The biggest damage boost is getting the core respawns right: reaching S4 and destroying the core at the first shockwave, reaching S6 and destroying the core before the 2nd shockwave, and reaching S8 after the core is destroyed.
Stalling QTE (red circles) can bring more damage if it allows you to respawn the core in time.
If you are having issues surviving the guns, you can time Crown’s S2 reaching 20 stacks to tank them.
Poison Spit hurts very badly at Stage 8; Crown’s shield isn't enough to tank it alone, so you will need to cover when the shield dies till the attack is over.
If running Mast: Romantic Maid, you can use her 2-stack Burst at your 2nd Burst in the fight for more damage than Crown’s Burst while still saving her Burst for the Poison Spit. For this to work, you have to manually take cover from the first shockwave.
Holding your Burst till after the Special QTE can result in more damage.
If using Red Hood and Mast: Romantic Maid, you get the most damage by timing your one-time Burst 1 and 3 Red Hood rotation with a 3-stack Mast Burst in Phase 2 (when the core is exposed, so the rest of the team can benefit from the teamwide ATK buff).
