Kaiju No 8 The Game Character Tier List
This Kaiju No 8 The Game tier list focuses on mid-to-late game progression and the Fierce Battle Area mode. I'll show you the best characters for DPS, buff/debuff support and shield/heal defender taking into account dupes/ascensions. You'll find the strongest options for the three roles in S and A-Tier with the B-Tier being decent alternatives. The C and D-Tiers are underpowered options that you start with but should avoid later for Fierce Battle Area. Let's dive into each unit individually below.
S-Tier Characters
| S-Tier | Why S-Tier |
|---|---|
 Reno Ichikawa 5-Star Shot/Ice Attacker | • A must-have DPS for Fierce Combat Area just due to his Ice Break dealing Ult-like damage as a regular skill • Ult deals great damage with a Crit Rate buff and deals AOE damage and Freezes which is an incredible mix of DPS and utility • Plus, you get SP back most of the time due to his passive • Lastly, offers excellent support damage off-turn as allies pop your Ice Crystals • Shines in single Kaiju battles |
 Sagan Shinomiya 5-Star Blunt/Fire Defender | • The best tank in the game • Sagan is a META tank that taunts enemies while boosting her own DEF and her Taunt is extended at A4 and grants team shields at A6 • She has an auto-revive so you don't need Akari • Sagan is also great offensively with her self DMG ups on Counter and overall buffs ATK with Ultimate plus CRIT dmg at A1 • A no-brainer must-have tank for Fierce Combat |
 Gen Narumi 5-Star Slash/Shot Attacker | • If Reno is for single Kaijus, Gen is best for crowds due to his massive AOE damage • Cycles speeding up buffs and ulting and then speeding up again • Has amazing shield breaker potential • Also has great boss-killing potential with his Core Exposed status for self-buffs and fast attacks • Overall a very flexible character both due to his kit and his Ultimate gauge effect for either Speed or Damage |
 Soshiro Hoshina 4-Star Slash Supporter | • One of the best 4-Stars and supports overall in Kaiju NO8 that's good with any DPS character • A crazy strong A1 dupe effect for massively buffing Crit Rate that's easy to unlock • Combine with Reno who already has a ton of Crit Rate and Hoshina will make sure Reno crits all the time • Instant Inspiration & Resourcefulness in a Pinch are also a must on your battle buddy for increased damage and debuff cleansing |
A-Tier Characters
| A-Tier | Why A-Tier |
|---|---|
 Kaiju No. 8 5-Star Blunt Attacker | • Since you get no weapons and Uniparts critting takes some extra steps but you can still do it yourself and your base stats are cranked way up along with perma buffs • Kaiju No. 8 is a great early carry since you don't need gear • That said, as you max out and evolve weapons and artifacts on other top-tier units I feel like this unit falls behind slightly • Still, it's a beast for Fierce Battle Area with the proper support characters like Mina and Soshiro because you do so much burst and adjacent damage and can also tank and taunt • Executes mobs so get them low with your team and have Kaiju finish them |
 Isao Shinomiya 5-Star Blunt Defender | • A must-have tank for any game mode if you don't have Sagan due to the ally shield protection making sure no one dies • Ult is both for damage and damage reduction • Shields give a damage boost while they last • Resurrects and heals himself on first dupe which is incredibly strong |
 Kikoru Shinomiya 5-Star Slash Attacker | • Gets progressively stronger the longer the fight is with each action • Her Ultimate is amazing team DMG utility because it lowers enemy DEF for the entire team to take advantage off • Best for Giant-Class Kaiju • Has great adjacent damage for AOE that is even better than Gen but she takes time to ramp up |
 Mina Ashiro 5-Star Shot Attacker | • One of the best boss-killers in the game so she's better for end-game bosses since she does more damage against Giant-class • While her DPS is okay Mina 5-Star is all about playing around her guaranteed Crit every 3 Focus stacks so make sure to buff her up before that and then Ult with it • Don't build her with Crit Rate since she auto crits with Focus and just buffs herself up before that big turn |
 Akari Minase 4-Star Shot Defender | • Amazing healer-based support that along with Isao makes sure your team doesn't die in any end-game mode, especially later floors of Fierce Battle Arena • Boosts Ultimate charge-up rate • Great for SP economy since you only need to use SP with her when you need to and you can otherwise let your 5-Star DPS use it • Revives allies on A6 which is incredibly OP |
 Mina Ashiro 4-Star Shot Supporter | • One of the better 4-Star characters that buffs your attackers and is really good with later support dupes • The cool thing about the Morale damage buff is that you only need to apply it once and then you don't have to spend SP for a while which is great for SP economy for 5-Star DPSs • Can also deal decent burst damage with her Ult and skills that trigger damage boost if there's Morale • She's kind of a mix between DPS and Support and she would be higher if she specialized in one |
B-Tier Characters
| B-Tier | Why B-Tier |
|---|---|
 Soshiro Hoshina 5-Star Slash Attacker | • Has decent AOE damage for clearing groups • The ult deals a lot of single target damage for bosses • Excellent at breaking shields • That said, Hoshina doesn't have as much utility as A-Tiers in terms of DPS with Kikoru also doing great damage and reducing DEF or Kaiju Kafka executing |
 Rin Shinonome 5-Star Shot Attacker | • Has great AOE damage with both her Combat Skill and Ult so she's strong for clearing groups • Great at breaking shields • Lacks boss-killing single target DPS • Overall she's a B-Tier DPS since she's slightly underpowered compared to the rest of 5-stars but still a good choice if you're a beginner |
 Ryo Ikaruga 4-Star Shot Supporter | • Excellent choice as autofill for your teams on Fierce Battle Area for team ATK/damage buffs • Has a permanent attack buff and plays mostly around his first skill and ult so you don't have to spend a lot of SP and therefore have more for your 5-stars |
 Kota Tachibana 4-Star Shot/Ice Defender | • Similar to 5-Star Mina in the sense that you want this guy for end-game Giant-class Kaiju battles to lower their ATK with Menacing Blow • Also freezes with Freeze grenade which is always good utility in a fight to debuff enemies • Otherwise deals okay damage and has a strong niche use so B-Tier |
C & D Tier Characters
All the other units in Kaiju No 8 The Game are just beginner options that offer some form of early-game DPS or weaker support. You can pick your favorites here and run whatever you want as you start but aim for the S, A and B-Tier options. Special shoutouts to Keiji Itami 4-Star who can debuff enemies, Haruichi Izumo who can lower ATK and Speed and 4-Star Kafka who is okay in his Ult Kaiju form.

Best Teams in Kaiju No 8 The Game (All Modes)
Now that you have a general idea of the best characters in Kaiju No 8 The Game individually, let's talk team comps. I'll recommend 2 team compositions each for Fierce Battle, Story progression and Giant-Class battles. Let's dive in:
| Game Mode | Team #1 | Team #2 |
|---|---|---|
| Fierce Battle Arena | Reno Ichikawa 5-Star Gen Narumi 5-Star Soshiro Hoshina 4-Star Sagan/Isao Shinomiya 5-Star This is a highly flexibile team comp that focuses on Reno's single and Gen's AOE damage with Soshiro's and Sagan's ATK buffs to make the most of Reno's single-target and Gen's AOE damage. | Kikoru Shinomiya 5-Star Reno 5-Star Mina Ashiro 4-Star Sagan Shinomiya 5-Star This is a team that relies on Kikoru's defense shred and I would fill it with Reno for single-target DPS since Kikoru already has good AOE. Mina is there for Morale buffs. |
| Story | Kaiju No. 8 5-Star Gen Narumi 5-Star Soshiro Hoshina 4-Star Isao Shinomiya 5-Star Kafka 5-Star is the best for story since you can easily get him and you don't have to worry about gear. Just support him with Soshiro and you'll clear story easily. Isao is there for tougher fights and you can replace him with Sagan if you have her. | Kaiju No. 8 5-Star Reno Ichikawa 5-Star Soshiro Hoshina 4-Star Isao Shinomiya 5-Star Same deal here with Kafka but you can combine him with Reno instead of Gen for more single-target DPS instead of Gen's AOE since Kafka deals pretty good AOE either way. |
| Giant-Class | Kikoru Shinomiya 5-Star Mina Ashiro 5-Star Soshiro Hoshina 4-Star Sagan Shinomiya 5-Star This is your go-to team to shred Giant Kaiju DEF with Kikoru and then burst them down with Mina's boss-killer damage. Soshiro and Sagan are there to boost all of this with their offensive buffs. | Kikoru Shinomiya 5-Star Reno Ichikawa 5-Star Soshiro Hoshina 4-Star Sagan Shinomiya 5-Star This is a similar team but you have more sustained DPS with Reno. |

Kaiju No 8 The Game FAQ
The best beginner damage unit that you don't need weapons for is the Kafka 5-Star Kaiju form. As for the weapon-based characters, 5-Star Reno, Gen and Kikoru are really strong with Reno having Crit and Freeze and Gen and Kikoru being great AOE (Kikoru shreds DEF).
The best support characters in the game are 4-Star Soshiro and Mina. Both buff your team's damage and can drastically improve specific DPS characters in your team.
As for the defender-oriented supports your best options are the 5-Star Sagan and Isao Shinomiya who taunt, are tanky themselves and either buff your ATK or shield your team.
I recommend the 5-Star Kaiju Kafka since you don't need to farm weapons for him. Get the Soshiro 4-Star support next to buff Kaiju Kafka and you can autofill the team with another DPS for a great early to mid-game start until you get the other 4-Star and 5-Star characters.
