In a game where updates arrive fast and the meta shifts constantly, knowing which units shine above the rest is crucial. Strong units don’t just help you progress through story stages—they’re the foundation for surviving endless waves, outlasting bosses, and clearing the hardest content in the game. Think of this list as your roadmap to building a powerful, efficient squad.

S-Tier: The Meta-Defining Units

These are the game-changers. If you have them, they should form the backbone of your team. With unmatched damage, utility, and crowd control, S-Tier units are essential for pushing into high-level content.

  • Michishibo (Unbound): The undisputed DPS king. His devastating damage plus bleed effect make him irreplaceable.
  • Magma Marine (5-Star): A burn-focused ground unit that melts waves of enemies, especially useful in Infinite Mode.
  • Slayer Mage (5-Star): A must-have for hill placement, offering long-range AoE that reliably clears waves.
  • Spider Boss (Chrollo) (5-Star): A hybrid of damage and crowd control, with poison effects and wide AoE.
  • Etri (Unbound): Packs heavy DPS while freezing enemies—offense and utility in one.
  • The Strongest One (4-Star): Despite his rarity, his insane single-target DPS can shred bosses in seconds.

A-Tier: Reliable High-Performers

Not quite meta-defining, but still incredibly strong. These units are versatile and effective across most content.

  • Fire Officer (5-Star): Solid AoE and utility, great for controlling waves.
  • Zorro (5-Star): Strong AoE and range, though expensive to place.
  • Mysterious X (5-Star): Brings valuable stun power and good DPS, limited only by his shorter range.
  • Kuroma (Yoko) (4-Star): A flexible DPS pick for filling team gaps.
  • Frezer (Final Form) (5-Star): Reliable AoE and utility, effective against most threats.

B-Tier: The Serviceable Squad

Good for newer players or mid-game progression, but they don’t scale well for end-game.

  • Zaruto (Sage) (4-Star): Solid DPS early, but long attack animations hold him back later.
  • Vegu (Mind) (4-Star): Strong DPS, but overshadowed by units with better AoE and range.
  • Ramen Grill-Master (4-Star): Low damage, but his cash generation makes him a helpful support pick.

C-Tier & D-Tier: Stepping Stones

These units are mostly filler, quickly replaced once better options arrive.

  • Spirit Detective (Orb) (3-Star): Decent starter unit, but low scaling makes him obsolete fast.
  • Jon Jo (3-Star): Early-game single-target damage, easily outclassed later.
  • Koro & Anti Magician (3-Star): Minimal utility, not recommended for serious teams.

The Current Meta: What Works Right Now

The All Star Tower Defense X meta revolves around maximizing damage output and AoE coverage. Unbound rarity units sit at the top, but smart use of 4-Star and 5-Star characters with the right traits can still build a championship-level team.

  • Best Traits: All Star, Genesis, and Tempest lead the pack with huge perks. Bloodlust and Companion are also excellent choices for squeezing more power out of your lineup.
  • Team Composition: A balanced squad usually mixes hill units, AoE powerhouses, and boss-melting single-target specialists.
