|S-Tier Units – The Meta Definers
S-tier units dominate the battlefield, offering exceptional damage, utility, and synergy. Whether you’re clearing waves or tackling bosses, these picks deliver consistent results.
- Michishibo – Bleed-focused and capable of one-shot kills.
- Spider Boss (Chrollo) – Devastating AoE with a Poison effect, though pricey to upgrade.
- Magma Marine – Unmatched burn damage with powerful ground coverage.
- Slayer Mage – One of the best Infinite mode units with massive DPS and range.
- Xero – The ultimate Support unit; essential for meta setups despite low damage.
- Trio Picks like Dark, Fina, and Sky God – Balance between DPS, debuffs, and elemental power.
If you’re aiming for progression or late-game scaling, focus your resources on these units first.
|A-Tier Units – Reliable and Versatile
A-tier heroes are strong across all content, though they might need more upgrades or synergy to match S-tier performance.
- Fire Officer and Sorcerer Killer apply consistent burn and bleed effects.
- Kuroma (Yoko) and Alligator offer flexible attack styles and heavy burst damage.
- Freezer (Final Form) and Mercury Guardian provide great range and crowd control.
- King Kaoe stands out as a Support unit, boosting ally damage by 75%.
These are safe, well-rounded picks for mid to late-game players.
|B-Tier Units – Solid but Situational
B-tier units are decent gap fillers when you’re short on top-tier picks. Some can shine early on or in specific maps.
- Ramen Grill-Master – The best money-generating unit in the game, perfect for early waves.
- Tony Stark, Zesty General, and Kosuke (TS) provide steady damage but need heavy investment.
- Super God Koku and Blackstache can still clear waves effectively with enough upgrades.
They’re not must-haves, but they get the job done.
|C-Tier Units – Story Mode Specialists
These characters are great for early progression or story missions but struggle in tougher Infinite or Arena modes.
- Future T and Anti Magician (Demon) are decent early hybrid options.
- Borul and Stampede deal strong single-target damage but have long SPAs.
- The Cursed One and Zio Brundo offer unique mechanics but inconsistent DPS.
Use them while building toward higher-tier replacements.
|D-Tier Units – Starters and Fillers
If you’re new, D-tier units can carry you through the first few story chapters. However, you’ll quickly want to replace them.
- Freezer, Ruffy, and Vegu provide basic damage but lack scalability.
- Captain and Ice Queen offer utility (burn or freeze) but fall short in raw stats.
- Jon Jo and Humble Swordsman are solid early-game DPS options only.
Upgrade them early or move on once you pull better units.
