Veguko IV, the Gogeta SSJ4 fusion, is a 7-star unit in All Star Tower Defense (ASTD) that you reach by summoning a base unit and evolving it twice with raid materials. The whole path runs through the Special Banner and the Otherworld Raid in World 2, so you need both a lucky (or persistent) summon and a group willing to clear the raid several times.
Quick answer: Summon “Koku and Vegu (Alternative)” from the Special Banner, then farm 8 Black Star Balls from the Otherworld Raid. Evolve the base into the 6-star “Koku and Vegu IV (Heroes)” with 4 balls, then evolve that into the 7-star “Veguko IV” with 4 more.
What you need before you start
The evolution chain has two hard requirements. First, you need the base fusion unit from the summon banner. Second, you need enough Black Star Balls, which only drop from the Otherworld Raid in World 2. Nothing else substitutes for these two items.
| Requirement | Where it comes from |
|---|---|
| Koku and Vegu (Alternative) — base unit | Special Banner (summon with Stardust) |
| Black Star Ball ×8 total | Otherworld Raid, World 2 |
Summon the base unit from the Special Banner
Farm Black Star Balls in the Otherworld Raid
Black Star Balls are the gating item for both evolutions. They come from the Otherworld Raid, which sits in World 2. A single successful clear yields one Black Star Ball, so plan on multiple runs.
Note: A solo attempt is likely to fail. Queue with a full lobby to save time instead of retrying alone.
Evolve into 6-star, then 7-star
The evolution is a two-step chain. Each step spends 4 Black Star Balls, and the final result is the shiny 7-star Veguko IV.
| Step | Result | Cost |
|---|---|---|
| Evolve Koku and Vegu (Alternative) | 6-star Koku and Vegu IV (Heroes) | 4 Black Star Balls |
| Evolve Koku and Vegu IV (Heroes) | 7-star Veguko IV | 4 Black Star Balls |
After the final evolution, you can equip a blessing and level the unit up. In practice the unit reaches high levels quickly, and it becomes ready to place in battle once leveled.
Veguko IV stats and abilities
Veguko IV is a fusion unit with a very low placement cost and two manual abilities. It starts cheap and scales up through upgrades that unlock stronger beam attacks.
| Attack | Damage | SPA | Range | Cost |
|---|---|---|---|---|
| Base placement | 4,902 | 3s | 60 | $100 |
| Ultra Red Beam | 1,860 | 4s | 60 | $600 |
| Big Bang Blue Beam | 1,003 | 6s | 80 | $1,000 |
Two manual abilities set the unit apart. “Bluff Beam” spawns multiple attacking clones that add extra damage output. The final upgrade unlocks “Positive Energy Stardust Breaker”, a full-screen cutscene attack that deals heavy area-of-effect damage.
How to confirm it worked
You know the process is complete when the unit in your inventory reads “Veguko IV” as a 7-star, shiny unit rather than “Koku and Vegu IV (Heroes)” or the base “Koku and Vegu (Alternative)”. If an evolution button is greyed out, the most common reason is that you have fewer than 4 Black Star Balls for that step, so return to the Otherworld Raid and clear it again until the count is met.
