Ultimate Tower Defense Tier List (2026) — Best Units Ranked

Ultimate Tower Defense (UTD) on Roblox is one of the longest-running anime tower defense games on the platform, and Update 51 just dropped on May 18, 2026 alongside Battlepass Season 9. With 14 rarity tiers, a shiny evolution system, and brand-new Tower Sets, knowing which units actually matter has never been more important.

This tier list ranks every notable unit in UTD based on raw damage output, AoE capability, late-game scaling, and how well they perform across Dungeon content (now extended to Floor 40) and standard maps. We've tested these units at comparable investment levels, factoring in both base and evolved forms. If you're wondering where to spend your gems, this is the guide.

S Tier — Best Units in Ultimate Tower Defense

These are the units that define UTD's current meta in Update 51. They carry runs, dominate Dungeon floors, and show up in virtually every competitive composition. If you're pulling from the summon pool and land one of these, you've won the lottery.

Thanos (Godly)

Thanos is the single most devastating unit in Ultimate Tower Defense right now. At Level 5, his ability can obliterate all enemies currently on the map plus 50% of your remaining units — it's a full board clear that no other unit comes close to replicating. In Dungeon content where waves stack up fast, that kind of reset button is the difference between clearing a floor and getting overwhelmed.

The trade-off is real: you lose half your deployed units when you pop the ability. But experienced players build around this by treating Thanos as a panic button and positioning expendable units as sacrifice fodder. When used correctly, he turns unwinnable situations into clean slates. He's been the top pick since his release, and Update 51's Tower Sets haven't changed that.

Greybeard (Divine)

Greybeard is the raw DPS king of UTD. His Tsunami ability deals 20x his displayed damage on a 20-second cooldown, which translates to some of the highest burst numbers in the entire game. His cone-shaped AoE attack means he's shredding multiple enemies with every activation, and when you stack that with shiny bonuses and a fully evolved 6th upgrade, the damage becomes absurd.

His one weakness is range. Greybeard's attack radius is noticeably smaller than other Divine-tier units, so positioning matters more than usual. You need to place him at chokepoints where enemies are forced to walk through his cone. Get the placement right and he'll outdamage everything else on your roster. Get it wrong and he's hitting air. At a 0.03% drop rate for Divine rarity (1,200 gems per pull), he's not easy to obtain, but he's worth every gem.

Blue Drago (Godly)

Blue Drago sits comfortably as the top DPS unit in the Godly rarity tier. His damage output is consistent across all content types, and he doesn't require specific team compositions to perform at a high level. Drop him on a map, upgrade him, and he carries. That simplicity is part of what makes him so valuable — he's a plug-and-play carry that works in any setup.

Where Blue Drago really separates from other Godly units is scaling. Most Godly-tier DPS units start falling off around Dungeon Floor 25-30, but Blue Drago keeps pace well into the higher floors thanks to his damage multipliers. If you're a free-to-play player who can't realistically chase Divine-rarity units, Blue Drago is your best investment.

Anyah (Godly)

Anyah is the most versatile unit in S-tier. She handles wave clear, single-target damage, and late-game scaling equally well, which means she fits into any team composition without creating gaps. Most S-tier units excel at one thing; Anyah excels at everything. That versatility makes her a permanent slot in your lineup from the moment you pull her.

Her shiny variant pushes her even further. With a 9% shiny chance on Godly pulls, you've got a reasonable shot at landing the enhanced version. Once she's shiny, max level, and evolved through Urahara with her 6th upgrade unlocked, she becomes one of the most complete units in the game. She pairs well with both AoE-focused and single-target compositions, which is rare at this level.

Jotaro Kujoa (Godly)

Jotaro Kujoa delivers some of the most consistent damage numbers in UTD. He doesn't have the flashy board-clear of Thanos or the burst of Greybeard, but what he does have is reliable, sustained DPS that never drops off. Wave after wave, floor after floor, Jotaro keeps putting out damage. That consistency is underrated in a game where most units have clear peaks and valleys.

He's also one of the better units to invest evolution materials into. His 6th upgrade adds meaningful power rather than a gimmick, and the investment payoff is immediate. If you're building a core team and need a DPS unit you can count on without worrying about positioning or ability timing, Jotaro is that unit.

Additional S-Tier Units

Four more units round out S-tier in Update 51. Gaara (Godly) brings powerful AoE control that locks down entire lanes while dealing solid damage. Crimson Doflamingo (Godly) is a high-damage specialist whose output rivals Blue Drago in the right setups. Todoroki (Divine) deals strong elemental damage with excellent scaling into late Dungeon floors. And Blackbeard (Divine) is a high-tier damage dealer whose kit complements the new Finisher Tower Set bonus introduced in Update 51.

A Tier — Meta Units

A-tier units are strong, reliable picks that can carry content when properly invested. They fall short of S-tier because they're either slightly less versatile, have lower damage ceilings, or require more specific team builds to reach their potential. An invested A-tier unit will still outperform an underleveled S-tier unit, so don't ignore these if they're what you have.

Bulma (Godly) and Tanjiro (Godly) lead the A-tier pack with strong all-around kits that work in most compositions. Colosal (Godly) brings massive AoE coverage that's especially effective on maps with tight corridors. Madika (Godly) and Berserk Gus (Godly) are both solid DPS options with good scaling, though they need more team support to match S-tier output.

On the Divine side, Dr. Joterio (Divine) and Whis (Divine) are both excellent units that just barely miss S-tier. Luffy Gear 4 (Godly) is a fan favorite with strong burst damage. Kid Naruto (Godly), Dio (Divine), and Rage Draco (Godly) round out the tier with reliable performance across most content types. Any of these units deserves investment if you're missing S-tier options.

B Tier — Sub-Meta Units

B-tier units get the job done during your early-to-mid progression but start showing cracks once you push into higher Dungeon floors. They're perfectly functional for farming standard maps and clearing content up through Floor 20-25, but their scaling doesn't hold up against the HP pools you'll encounter beyond that.

Muzan (Godly) and Rieza (Godly) are the strongest B-tier picks, both offering decent damage that carries through mid-game content. Eato (Divine) and Raruto Six Paths (Divine) have higher rarity but lower practical performance than the best Godly units, which is a common trap for newer players. Renjae (Godly), Lite (Divine), Diavolo (Godly), and Monkey (Godly) are all serviceable but should be replaced as you pull better options.

If you're currently running B-tier units as your main carries, focus your gems on pulling from the summon pool. At a 0.03% rate for Divine and roughly 1 in 11 Godly pulls being shiny, your resources are better spent chasing upgrades than investing evolution materials into B-tier units.

C Tier — Low-Meta Units

C-tier units are functional in early content but get outclassed quickly. Super Drago (Divine) and Rengo (Divine) are the most notable names here — both have Divine rarity but underwhelming kits that don't justify the investment. Armored Titan (Godly), Bomb Guy (Godly), and Nagato (Godly) are all examples of Godly units that simply can't compete with the S and A-tier options above them.

Goku Black Rose (Divine), Sasuke (Godly), Car-4 (Godly), and Gojo (Godly) round out C-tier. Some of these were once higher-ranked but have been power-crept by newer units. The biggest mistake you can make with C-tier units is spending evolution materials on them. Keep them at base level, use them to fill slots when needed, and replace them the moment you pull something from B-tier or above.

Tier List Summary Table

Here's the full tier list in table format for quick reference. Use this when you're building teams or deciding which units to invest in next.

How We Ranked These Units

Our rankings are based on four core factors: raw DPS output (damage per second at max investment), AoE capability (how effectively the unit clears grouped enemies), late-game scaling (performance in Dungeon Floors 30-40 and beyond), and ability power multipliers (game-changing abilities like Greybeard's 20x Tsunami or Thanos's board clear).

We tested each unit across standard maps, Dungeon content through Floor 40, and competitive scenarios. Units were evaluated at comparable investment levels. A fully evolved shiny unit with its 6th upgrade will always outperform a base version of the same unit, so we compared evolved-to-evolved and base-to-base separately to keep rankings fair.

The evolution system is a major factor in UTD's meta. A unit must be shiny, at max level, and have the required materials before you can evolve it through Urahara. All evolved units gain a unique 6th upgrade that can dramatically shift their power level. Some C-tier base units become B-tier when evolved, but none of them jump high enough to compete with evolved S-tier units. The gap at the top is real.

We also considered Update 51's Tower Sets — Fighter, Brawler, Guardian, Finisher, and Dragon. These set bonuses add a new layer of synergy that rewards building your team around units in the same category. A team of 5 S-tier units from different sets will still perform well, but a team that activates a set bonus gets a measurable edge. It's worth checking which set your favorite units belong to before committing resources.
