The 7-star Omega Dragon is the in-game version of Omega Shenron in Roblox All Star Tower Defense, developed by Top Down Games. Reaching it takes two things: the base 5-star unit from a special banner and a stack of Black Star Balls earned through a raid. Once maxed, the unit ends with a full-map nuke that clears crowds in a single hit.

Quick answer: Summon Ice and Nova Dragon from the Dual Starhunt special banner, collect eight Black Star Balls from the Otherworld Raid, then evolve twice — four balls to reach 6-star Syn Dragon, and four more to reach 7-star Omega Dragon.

What you need before evolving

Two components complete the full evolution chain. Gather both before you start, since the evolution consumes all eight Black Star Balls across the two upgrade steps.

Evolution steps from base unit to 7-star

Open the Dual Starhunt special banner in the summon area and pull until you land Ice and Nova Dragon. This 5-star unit is the starting form for the entire chain.

Run the Otherworld Raid in Adventure mode until you have eight Black Star Balls in your inventory. You cannot finish both evolution stages without the full eight.
Evolve Ice and Nova Dragon into the 6-star Syn Dragon using four Black Star Balls. Syn Dragon lands at 7,677.67 damage, 60 range, a 5.00 second attack speed, and a 1,000 placement cost.
Evolve Syn Dragon into the 7-star Omega Dragon using the remaining four Black Star Balls. Once equipped, the unit shows a red and black swirling aura in the lobby, which confirms the evolution went through.

Note: Feed XP units afterward to raise Omega Dragon’s level. At level 125, it reaches its base placement stats and unlocks its full upgrade path in a match.


Omega Dragon stats and upgrade path

Omega Dragon starts as a ground unit and becomes a hybrid unit at Upgrade 4, meaning it can then hit air enemies as well. Its attack begins as a cone AOE and shifts to a full circle or sphere visual at later upgrades, with range and damage climbing sharply toward Upgrade 10.

State (Lv. 125)DamageSPARange
Base placement54.1k4s70
Max (Upgrade 10)384M10s200

The maxed upgrade costs $9.3M in-match, and the unit sells back for $8.75M. Damage scales through the upgrades, with the biggest black sphere attack animation and widest range appearing across Upgrades 8 through 10.


Abilities and the Negative Energy Rebirth nuke

Omega Dragon carries two special abilities that unlock at set upgrade points. The second one is the main draw for late-wave clears.

AbilityUnlocks atEffect
Negative Energy SwarmUpgrade 7Active attack ability
Negative Energy RebirthUpgrade 10 (max)Full-map nuke, 7-second charge, roughly 500M damage

Negative Energy Rebirth takes 7 seconds to charge before it fires, then hits every enemy on the map for around 500M damage. Against a high-HP test dummy it lands that full amount, which makes it a reliable answer to dense or high-health waves once the unit is fully upgraded.

The whole chain comes down to one summon and one raid grind. Pull Ice and Nova Dragon, farm eight Black Star Balls from the Otherworld Raid, evolve through Syn Dragon, and finish at Omega Dragon. Level it to 125, upgrade to 10 in a match, and you have a hybrid unit that ends fights with a full-map nuke.
