To get Gear 4th in Anime Fighting Simulator, equip Rubber Fruit, have Gear Second unlocked, then complete Rubber Captain Luffy’s questline near the Monkey boss island and turn in the final Alligator boss mission.
Gear 4th is a transformation for Rubber Fruit users, so the unlock starts before you even talk to Luffy. Once you meet the two prerequisites, the rest is a six-mission chain built around paired stat training, Rubber Captain kills, and one Alligator boss clear.
Gear 4th requirements and Luffy location
| Requirement | Details |
|---|---|
| Rubber Fruit | Must be equipped before starting the questline. |
| Gear Second | Must already be unlocked before Gear 4th missions begin. |
| Quest NPC | Rubber Captain (Luffy). |
| Starting area | Small island near Celerina Island, close to the Monkey boss area. |
| Quest flow | Return to Luffy after each mission to receive the next one. |
Before starting the Gear 4th questline, make sure Rubber Fruit is equipped and Gear Second is already unlocked. If either one is missing, Rubber Captain (Luffy) will not start the Gear 4th missions.
Find Rubber Captain (Luffy) on the small island near Celerina Island, close to the Monkey boss area. Players also describe this as the island behind the arena where Monkey spawns. After every mission, go back to Luffy to turn it in and receive the next objective.
How to complete Luffy’s Gear 4th missions in Anime Fighting Simulator

Fast clears for the training and boss grind
The training missions move faster when you use champions that train paired stats together. For the first and fifth missions, prioritize champions that help with Strength and Durability; for the fourth mission, switch to champions with Speed and Agility bonuses.
KEY!Pay attention to the difference between increments and total stats. The 3,000, 1,000, and 5,000 tasks count training gains earned during the mission, while the 100 trillion Strength and 100 trillion Durability mission checks your actual stat totals.
Server hop after each Rubber Captain kill instead of waiting through the full respawn in one server; repeat until all eight kills are done.
Transformation skills in Gear 4th
| Skill | Use |
|---|---|
| Barrage | Throws out a fast series of punches, useful against groups. |
| Kong Organ | Delivers a strong multi-hit punch attack for big damage. |
| Bazooka | Sends a heavy forward punch with strong impact for single targets. |
| King Kong Gun | Creates a massive fist attack that lands like a meteor punch. |
After the final Alligator mission is turned in, Gear 4th becomes permanently available as a transformation. Its exact damage boost and damage-reduction numbers have shifted across updates, so focus on what the moves actually give you in fights: fast pressure, heavy hits, and a large signature attack.
Outdated Gear 4th methods and common mistakes
Older Gear 4th routes involving Bang or 5T Strength, 5T Durability, and 5T Chakra should not replace the current Rubber Captain (Luffy) questline. The current route starts with Rubber Fruit and Gear Second, then follows Luffy’s six missions.
The main mistakes are starting without Rubber Fruit or Gear Second, farming the wrong Rubber Captain enemies, skipping the 5,000 Strength and 5,000 Durability increment mission, and ignoring the Alligator timer board on Desert Island.
Frequently Asked Questions
Do you need Rubber Fruit to get Gear 4th?
Yes. You need Rubber Fruit equipped before Rubber Captain (Luffy) will start the Gear 4th mission chain.
Do you need Gear Second before Gear 4th?
Yes. Gear Second must already be unlocked before you can begin Luffy’s Gear 4th quests.
Where is Rubber Captain Luffy located?
Rubber Captain (Luffy) is on the small island near Celerina Island, close to the Monkey boss area. It is also described as the island behind the arena where Monkey spawns.
What does Strength or Durability increment mean?
An increment means a training gain earned during that mission, not your total stat value. The 100 trillion Strength and 100 trillion Durability mission is the separate total-stat check.
How do you make the Rubber Captain kills faster?
Use server hopping. Defeat Rubber Captain, switch servers, find him again, and repeat until you have all eight kills instead of waiting around 10 minutes in one server.

Where does Alligator spawn?
Alligator spawns at the center of Desert Island. Check the information board near the boss area to see when it returns.
Is the old Bang or 5T stat method still correct?
No. The old Bang route and 5T Strength, 5T Durability, and 5T Chakra notes belong to older methods. Use the current Rubber Captain (Luffy) questline with Rubber Fruit and Gear Second.
