Zenless Zone Zero Billy Best W-Engine
Steel Cushion is an amazing W-Engine to have on Billy as it boosts the wearer’s Physical damage output. You can also go for the Cannon Rotor or Housekeeper if you don’t have Steel Cushion yet.

Zenless Zone Zero Billy Best Drive Disc
If you’re looking to boost Billy’s damage even further, equip him with four pieces of the Woodpecker Electro set for bonus Crit damage for performing almost any attack, including each basic attack. Just remember that this set benefits from you having as much Crit Rate as possible. Then, you can use two pieces of either Fanged Metal or Puffer Electro for additional damage.

This attack will inflict a large amount of Daze and can launch small targets. | Active skill will inflict 80% more Anomaly Buildup when there are 2 or more Physical attribute Agents on the team.

Zenless Zone Zero Billy Mindscape Cinema
Unlocking Mindscape Cinema levels in Zenless Zone Zero requires you to pull duplicates of an Agent. They provide powerful upgrades for a character but aren’t necessary to clear content. Since Billy is a free character, however, you'll naturally be one step closer to getting all of his upgrades.

1 | Dazzling Entrance | Billy gains an additional 1.8 Energy when hitting enemies with Dash Attack or Dodge Counter. This effect can trigger once every 5 seconds. |
2 | Roaming Gunslinger | Dodge Counter deals 20% more damage. Rolling Shots during Basic Attacks are counted as dodges, giving the move invincibility and the ability to trigger Perfect Dodges. A Perfect Dodge triggered from Rolling Shots will become a Dodge Counter. |
3 | Teachings of the Starlight Knights | All skill levels are increased by 2. |
4 | Starlight Ballistics | The CRIT Rate for Billy's EX Special Attack is increased based on the distance of the target. The skill will gain a higher CRIT Rate boost the closer an enemy is up to a maximum of 32%. |

6 | Corrupting Energy Field | Billy's damage is increased by 7% whenever he accumulates 10 enemy hits or triggers a Perfect Dodge. This can stack up to five times and will last until Billy is staggered by an attack. |
Zenless Zone Zero Billy Materials
If you plan on tackling Zenless Zone Zero endgame content, you’ll need to raise the levels of your characters and enhance their abilities. You’ll need the following items to do that with Billy.
- Physical Chips (skill enhancement material)

These materials can be obtained by doing Combat Simulation Training at the HIA Club. You might also be able to find some of these items for sale at the 141 store so be sure to check what they have available at least once a week.
How to Get Billy in Zenless Zone Zero
You will automatically unlock Billy shortly after starting the game. However, you can earn additional copies of Billy to upgrade him in either the standard or event banners. As an A-Rank character, although it's more common to get them than an S-Rank, it's not possible to narrow down your search. Eventually, though, you're bound to get another drop of Billy.
