Best Meta Weapons from Each Class in KAIJU NO. 8 THE GAME
1. Best Assault Rifle – AR-Boreas
I believe the AR-Boreas is a top since in the Assault Rifle category, since it’s Reno Ichikawa’s signature weapon. This weapon lets him perform even better and provides a CRIT Rate increase of 24 per cent.
So if you equip this to 5* Reno, after he uses a Combat Skill, it applies an Ice DMG dealt buff for three turns and increases Ultimate Gauge Charge rate for three turns. The best part is that this effect stacks up to two times.
2. Best Axe – Ax0112
Coming to Axes, the Ax-0112 stands out as one of the best options in the game, especially for Kikoru Shinomiya. If you’ve unlocked 5* Kikoru or even 4* one, you should definitely equip this one to her, as it provides a Slash DMG boost of 20 per cent.

Ax-0112 is one of the best, offering the Slash DMG effect. With this, before the equipped unit attacks a Kaiju that already has a debuff, it applies the DMG dealt buff to the equipped unit. Plus, after the equipped unit activates Combat Skill, it applies the ATK buff to the equipped unit. Max 3 stack(s).
3. Best Twin Swords – SW-Susanoo
For Twin Swords, SW-Susanoo, Soshiro Hoshina’s signature weapon, is one of the best options, which is also available in gacha along with him. This weapon works great with 5* Soshiro and provides a CRIT DMG effect.

So, before the equipped unit activates Ultimate, this weapon increases Combat Skill and Ultimate DMG for three turns. And after the unit uses a Combat Skill, if there are two or fewer Kaiju on the battlefield, it gives a SPD buff to the unit for two turns.
4. Best Gunsword – GS-3305
I love Gunswords because it’s perfect for Gen Narumi, who is my favorite unit. And in this class, GS-3305 is a solid option for Units whose optimal weapon type is Gunsword, especially 5* Narumi. I was lucky enough to unlock both, and this provides a Slash DMG boost of over 20 per cent.

Talking about its other effects, after the equipped unit, let’s say Narumi, uses a Combat Skill, it grants a DMG dealt bonus, which further stacks up to three times. And after he activates his Ultimate, it applies the Ultimate Gauge Charge bonus for two turns.
5. Best Cannon – T-25101985
Now, Mina Ashiro fans will be intrigued by this part as Cannon is her optimal weapon. While all three 5* cannons are strong, this one is much easier to obtain and also provides a huge Shot DMG Dealt bonus.

Plus, you should equip this one to 5* Mina, as before she uses a Normal Attack, this weapon applies the ATK buff and increases Ultimate Gauge Charge rate for two turns. And this also stacks up to two times, making Mina more deadly.
6. Best Gatling Gun – GG-5012
Now, for the Gatling Gun category, GG-5012 is one of the best weapons and fits perfectly well on Rin Shinonome. So, if you’ve unlocked 5* Rin, you should definitely focus on getting either this or GG-Iapetus. It also provides Shot DMG Dealt bonus.

If there are three or more Kaiju on the battlefield, this weapon boosts the equipped unit’s ATK. Moreover, when your equipped unit uses a Combat Skill or Ultimate against a Kaiju with 50% or less HP, it applies more DMG buff.
7. Best Gauntlet – Fs-1002
Now, I have a soft spot for Gauntlet, as Isao Shinomiya uses them, who sadly died in the anime. In the game, we can at least collect him for the squad, and equip him with Fs-1002, which is one of the best gauntlets among the 3x 5* ones. As a Defender, this works really well as it provides a huge DEF buff.

For instance, if you equip this one to 5* Isao, he will gain a DEF bonus for one turn after he takes an attack. And if your equipped unit has a shield like Isao, it also gives all allies a DMG Taken Reduction buff.
8. Best Powered Suit – PS-Dobermann 52
Currently, powered suits are a bit limited since there’s no 5* option, but PS-Dobermann 52, which is a 4* unit, is the best choice currently. You can equip it to someone like Eiji Hasegawa if you plan to include him in your squad. This weapon provides an ATK boost, and when there is a Core Exposed Kaiju on the field, it increases the equipped unit’s DMG.
9. Best Handgun – HG-Beetle 15
Handguns are also in a similar situation as the Powered Suit, since there is no 5* option yet, and I don’t think it is arriving anytime soon. However, the HG-Beetle 15, a 4* weapon, is the best choice now.

It works well with Hibino Kafka, and you unlock both for free, so you can use them until you get better ones. This weapon particularly provides 28% ATK boost, and after, let’s say Kafka activates his Combat Skill, it will grant him DMG dealt bonus for two turns.
