Universal Tower Defense X tier list rankings

Here is our Universal Tower Defense X tier list:

S+ Tier Units

The S+ tier contains the strongest units currently available in Universal Tower Defense X. These characters offer exceptional damage, utility, and scaling, making them the best choices for almost every game mode.

Joyful Captain

Widely considered one of the strongest units in the game. Joyful Captain delivers incredible damage and remains useful throughout all stages of progression.

King Sailor (Unrivaled)

A meta-defining unit that fits into nearly every high-level team composition.

Jinoo (Shadow Monarch)

One of the highest DPS units in Universal Tower Defense X. His damage output and late-game scaling make him a core member of many endgame teams.

The Strongest in History

Offers some of the best boss-killing potential in the game and scales extremely well with upgrades.

The Strongest of Today

A powerful damage dealer with excellent performance in Story Mode, Infinite Mode, and Raids.

Ancient Mage (Sage)

Combines strong damage with excellent utility, making it one of the most versatile units in the game.

S Tier Units

S-tier units are only slightly behind the S+ tier and remain excellent choices for all content.

• Gluttonous Warlord (Despair)
• Triple Threat (Unrivaled)
• Marine Hero (Grand Fist)
• Alpha Devil (Omega)
• Phantom Captain (Carrier)
• Dragon Guy (Silverite)
• Mimicry Sorcerer (Cursed Love)
• Love Goddess

These units can comfortably clear endgame content and often appear in meta team setups.

A Tier Units

A-tier units are powerful options that perform well in most situations but are generally outclassed by the top-tier characters.

Some of the strongest A-tier units include:

• Prodigy Mage (Apprentice)
• Virtual Idol (Super Star)
• Sharpshooter King (Trapper)
• Crow Shinobi (Reanimated)
• Sasku (Great War)
• Rule (ROOM)
• Underworld God

If you don't have access to S-tier units, many A-tier characters can still carry you through difficult content.

• The Drink (Survivor)
• Psycho (100%)
• Koyote (Number One)
• Super Roku (Enraged)
• Ultiorra (Oblivion)
• Shunks (Conqueror)

These units are perfectly usable for Story Mode and early Infinite Mode but eventually get replaced by stronger alternatives.

Players should avoid investing significant resources into:

• Nejo

• Fire Foot Cook
• Footballer (Ego)
• Laffy
• Nutaru
• Gaaru
• Orahemi
