Units

Introduction

The All Star Tower Defense unit roster is one of the largest in Roblox tower defense, with hundreds of anime-inspired units ranging from 3-star fodder to 7-star hyper-evolutions. Each unit has a star rating that drives its base power, upgrade potential and deployment cost. Units evolve to unlock new forms and abilities, and a small chance exists to obtain a shiny variant of any unit when summoning or evolving. Limited units from events, holidays and special banners are often only obtainable through trading once their banner ends. Understanding star levels, evolution paths and the difference between ground, hill and ranged units is the key to building a competitive team. This section catalogues the roster, explains how units grow, and helps you decide which units deserve your star upgrades and traits.

Core Mechanics

Every ASTD unit starts at a base star level and can be upgraded. Star upgrades multiply a unit's base stats, and each star tier also raises the unit's deployment cost. Evolution is separate from star upgrades: evolving a unit transforms it into a new form with different abilities and higher stats. Some units evolve during battle when they reach certain upgrade levels, while others evolve in the lobby through evolution items. Shiny variants are cosmetic reskins that share the same stats as the standard unit; the community estimates a roughly 10% chance to roll one, though the rate is not officially confirmed. Unit types matter for placement: ground units walk the path, hill units use hill slots for bonus damage, and ranged units attack from a distance. Limited units are periodically rotated out of the Summon Gate and can only be obtained through trading once removed, which drives their market value.

Advantages

A deep unit roster means there is always a unit for every situation and play style. The star system gives long-term progression goals: you can feed duplicate units to upgrade your favorites all the way to 7-star hyper-evolutions. Evolution adds meaningful choice, letting you decide which form of a unit fits your team rather than being stuck with a static stat stick. Shiny variants give collectors a chase goal that does not affect competitive balance, so cosmetics coexist with gameplay progression. Limited units create trading value and make events feel rewarding, since pulling a rare event unit gives you a valuable asset you can trade later.

Challenges

The sheer size of the roster makes it hard to know which units are worth investing in, especially for new players. Star upgrades consume duplicate units, so focusing the wrong unit wastes valuable collection resources. Evolution paths can be long and expensive, and a unit's pre-evolution form is often much weaker than its final form, which can mislead players who level it early. Shiny hunting is a gamble — the unconfirmed rate means some players spend enormous resources chasing a cosmetic variant. Limited units create scarcity anxiety: missing an event unit may mean waiting months or paying inflated trade prices. Finally, a huge roster means the meta constantly shifts as new units are added, so today's best unit may be replaced next update.
