Ace Eater is a Secret-rarity unit added to Universal Tower Defense Z in Update 4.75, built around Don Lorenzo from Blue Lock. He works as both a heavy DPS pick and a debuffer, and his evolved form pushes Yen income, drops enemy attack speed, and hits groups with stacking crowd control. Every one of his abilities is tied to an upgrade slot, so his power grows only as you invest.
Quick answer: Clear Act 1 of the Universal Football Event for a 15% drop chance at Ace Eater. Complete the event map 7 times and the unit is guaranteed.
How to get Ace Eater from the Universal Football Event
Ace Eater drops from the Universal Football Event map. Beating Act 1 gives you a 15% chance at the unit per clear, and 7 completions of the map guarantee it. A Shiny Ace Eater can also come out of the same event as a reward.
The event map plays like a soccer match layered on top of tower defense, so your unit roles decide where they line up on the pitch.
You confirm the pull worked when Ace Eater lands in your unit collection after a clear. If it does not appear, you simply missed the 15% roll for that run. Keep completing the map, since the 7th completion pays out the unit no matter what.
How to evolve Ace Eater into Ace Eater (Zombie)
Ace Eater upgrades into Ace Eater (Zombie). Talk to the Evolutions NPC, select the unit, gather every item below, then press Evolve.
| Item | Amount |
|---|---|
| Universal Fragment | 3 |
| Petal Fragment | 4 |
| Phantom Fragment | 10 |
| Football | 10 |
| Sealed Rose | 1 |
| Gold | 25,000 |
Fragments come from clearing Acts in the Legend Stage and the Challenge maps, and you can also buy them from the Merchant with Gold, which most game modes hand out on clear. Football and Sealed Rose are exclusive to Act 1 of the Universal Football Event map, with Sealed Rose sitting at a 25% drop chance there.
All Ace Eater (Zombie) passives and how they unlock
The core passive, Gimme Money, opens up a new ability at each upgrade tier. Nothing is active by default beyond placement, so you unlock the full kit by upgrading through all four levels.
| Passive | Unlocks at |
|---|---|
| Swallow them Whole | Placement |
| Yo, Michael | Upgrade 1 |
| Ace Eater | Upgrade 2 |
| Zombie Dribble | Upgrade 3 |
| Absolute Defense | Upgrade 4 |
Swallow them Whole
Active from placement. On hit, it stamps a Yen value of 250 onto an enemy, and that value climbs by 125 each second up to a 1,250 cap. When the enemy is taken down, you collect the built-up value as Yen. Each upgrade boosts the effect by 25%, and it can only apply to 25 enemies per wave.
Yo, Michael
This active ability costs 25,000 Yen and starts at a 50% success rate. Land it and you double the Yen gain from Swallow them Whole for 2 waves. Fail and your accumulated Yen resets to 0. Every failed attempt raises the success rate by 12.5% until it lands.
Ace Eater
The unit always Cross Passes to the furthest ally. Passing the ball hands the receiver a -20% SPA buff for 12 seconds. When that receiver passes on, the second receiver instead takes a +10% SPA penalty for 15 seconds.
Zombie Dribble
While Ace Eater is not holding the ball, he fires a full AoE attack every 3x SPA. Enemies caught in range are hit with a set chain of effects and each affliction can land twice per enemy.
- +20% Damage taken for 15 seconds
- Stun for 4 seconds
- Confusion for 3 seconds
- Move 2x faster for 7 seconds
Absolute Defense
An active ability that grants Stock Invincibility against Boss Attacks for 15 seconds. It has a single global use, so save it for a critical boss moment.
Deployment cost and quick facts
| Detail | Value |
|---|---|
| Rarity | Secret |
| Added in | Update 4.75 |
| Deploy cost | 500 Yen |
| Base drop chance | 15% (Act 1, Universal Football Event) |
| Guaranteed at | 7 event map completions |
| Sealed Rose drop rate | 25% (Act 1) |
| Shiny variant | Yes, from the event |
Between the money-stacking economy of Swallow them Whole, the SPA swings from Ace Eater, and the layered stun-and-confuse chain in Zombie Dribble, the evolved unit rewards a full four-upgrade investment more than most. Get him onto the board early, farm the event for the Football and Sealed Rose drops, and upgrade through every tier to unlock the boss-shredding Absolute Defense at the top.
