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.
| Requirement | Where to get it | Amount |
|---|---|---|
| Ice and Nova Dragon (5-star base unit) | Dual Starhunt special banner | 1 |
| Black Star Ball (evolution item) | Otherworld Raid (Adventure mode) | 8 |
Evolution steps from base unit to 7-star
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) | Damage | SPA | Range |
|---|---|---|---|
| Base placement | 54.1k | 4s | 70 |
| Max (Upgrade 10) | 384M | 10s | 200 |
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.
| Ability | Unlocks at | Effect |
|---|---|---|
| Negative Energy Swarm | Upgrade 7 | Active attack ability |
| Negative Energy Rebirth | Upgrade 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.
