Zephyrus Mech Strategies

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Zephyrus Mech Jail King Monarch Boss Strategies

Here is a breakdown of the battle strategies against the boss:

Carry HP and SP Recovery Items

Before engaging the boss, bring a stock of HP and SP recovery items. These items can be bought from accessible vending machines, food stands, store, and restaurants. You can also buy ingredients from Sophia’s Shop and other real world stores. Then, cook these ingredients for additional HP and SP items through Joker’s Kitchen.

Joker’s Kitchen Guide

Engage from the sides or behind

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Zephyrus Mech Jail King Monarch Attack from the Sides or Behind

Strafing to the side or back is generally a good strategy against Zephyrus Mech as most of its damaging attacks will only hit you if you are standing directly in front of it. The only exceptions are its cluster missiles that home in on you and its laser blasts (both ground and airborne).

Land Debuffs

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Zephyrus Mech Jail King Monarch Land Debuff

Start the battle by landing multiple debuffs on Zephyrus Mech. Debuffs can be in the form of attack power decrease (Tarunda), defense power decrease (Rakunda), and evasion/critical evasion power decrease (Sukunda). These debuffs can be accessed by Joker (from Arsene and other Personas). Another option is by using Debilitate for an all-in-one debuff. This special debuff can be accessed by Joker (from other Personas) or Wolf.

Cast Buffs

Follow-up the debuffs with party members buffs. Buffs can be in the form of attack power increase (Matarukaja), defense power increase (Marakukaja), and evasion/critical evasion increase (Masukukaja). These buffs can be accessed by Joker (from other Personas), Skull, and Queen. Another option is by using Heat Riser for an all-in-one buff. This special buff can be accessed by Joker (from other Personas) and Wolf. You may also use Charge and Concentrate buffs to boost your damage even further if available. These buffs can be accessed by Joker (from other Personas) and Skull.

Remove Enemy Buffs

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Zephyrus Mech Jail King Monarch Remove Buffs

Zephyrus Mech has all-in-one buff skill similar to Heat Riser. In order to remove it, use a Dekaja debuff skill. The debuff can be accessed by Joker (from other Personas) and Wolf.

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Zephyrus Mech Jail King Monarch Heat Riser Buff

When facing the boss again for Painful Past requests, it may use the buff skill repeatedly. Always check the boss data to ensure that the boss will not gain an advantage from you.

Use Elec and Nuke Attacks

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Zephyrus Mech Jail King Monarch Supernova

Zephyrus Mech is weak to Electricity and Nuclear attacks which Skull, Queen, and Joker can capitalize. Continue on using elemental attacks in order to break the shields and stagger the boss. Make use of narrow range elemental skills if you’re close and wide range elemental skills if you’re far from the boss.

Avoid Special Moves like Supernova

While damaging the boss, it will unleash its unique attacks to your party. For the first phase of the battle, the boss will rely to his mech suit skills to do the damage.

Capitalize on Terrain Gimmicks

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Zephyrus Mech Jail King Monarch Use Terrain Gimmicks

There is only one terrain gimmick accessible during the first phase of the boss fight. Look for a capture point to get near to it.

Terrain Gimmick Strategy

Unleash Showtime Attacks

Persona 5 Strikers - Osaka Jail King Zephyrus Mech Unleash Showtime Attacks

While engaging Zephyrus Mech, you may build up your showtime gauge. When it’s available, unleash the showtime attack against the boss. If Joker’s showtime attack is available, make sure he has the right Persona that can capitalize on the weakness of the boss. Also, there is a consumable item that will quickly boost your Showtime gauge build up so feel free to use it against the boss.

Akira the Hero Strategies

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Akira the Hero Jail King Monarch Boss Strategies

Party Build

The party is still the same and cannot be changed mid-battle.

Land Debuffs

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Akira the Hero Jail King Monarch Boss Strategies

In similar fashion, land debuffs on Akira the Hero. Either use a -nda buff or Debiliate. These debuffs can be accessed by Joker (from Arsene and other Personas) and Wolf.

Cast Buffs

Likewise, cast party member buffs to all party members. Either use a -kaja buff or Heat Riser. These buffs can be accessed by Joker (from other Personas), Skull, Queen, and Wolf. You may also use Charge and Concentrate buffs to boost your damage even further if available. The buffs can be accessed by Joker (from other Personas) and Skull.

Keep using Elec and Nuke Attacks

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Akira the Hero Jail King Monarch Use Electricity Attacks

Same with Zephyrus Mech, Akira the Hero is also weak to Electricity and Nuclear attacks. However, the boss loses his resistances to Fire and Ice attacks. Bombard him with skills using Joker, Skull, and Queen’s elemental attacks.

Capitalize on Terrain Gimmicks

There is only one terrain gimmick accessible during the first phase of the boss fight. Quickly transfer on them and use Phantom Dash to hurt the boss.

Terrain Gimmick Strategy

Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Akira the Hero Jail King Monarch Terrain Gimmick Armored Zephyrus Broken Wing PartsZephyrus Mech Broken Wing Parts Jump from the broken and unleash an Physical attack on Akira the Hero. Effective when the boss is under Shock status.

Deal Technical Damage with Phys, Gun and Nuke Attacks

Persona 5 Strikers - Osaka Jail King Akira the Hero Deal Technical Damage

When the boss is inflicted with a status ailment such as Shock, deal technical damage by using Physical, Gun, and Nuclear attacks. Have all party members switch turns in dealing Physical and Gun attacks while Joker and Queen consistently heals the party. Also, switch between Joker and Queen to avoid running out of SP.

Avoid Special Moves like Supernova

While damaging the boss, it will unleash its unique attacks to your party. For the second phase of the battle, the boss will rely to sword skills to do the damage.

Special Move Strategy
Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Akira the Hero Jail King Monarch Justice SlashJustice Slash Akira the Hero mainly uses melee attacks with his sword and will often perform a three-strike combination. His swings are quite slow but have wide range so dodge to the side to avoid getting hit. The boss can also fire lasers from his sword.
Persona 5 Strikers - Osaka Jail Shadow Akira Konoe Akira the Hero Jail King Monarch Dynamic MeteoDynamic Meteo Akira the Hero will do a quick jump that sends a shockwave down the floor. Use double-jump to avoid getting hit by the waves.

Unleash Showtime Attacks

While engaging Akira the Hero, you may build up your showtime gauge. When it’s available, unleash the showtime attack against the boss. If Joker’s showtime attack is available, make sure he has the right Persona that can capitalize on the weakness of the boss. Also, there is a consumable item that will quickly boost your Showtime gauge build up so feel free to use it against the boss.
