Navigating the expansive maps of World Fighters Simulator requires more than just raw strength; it requires a strategic approach to progression. One of the most effective ways to boost your character's potential is by completing every World Fighters side quest available. These hidden objectives often provide massive multipliers, such as the coveted 1.5x power boost, which can significantly shorten the grind for endgame content. Following recent quality-of-life updates in 2026, players now benefit from auto-claim rewards, making it easier than ever to stack bonuses while focusing on combat.
In this guide, we will walk you through the precise locations of every side quest NPC, the specific requirements to clear their challenges, and the rewards you can expect. Whether you are hunting for the secret Broly unit or trying to survive the Tempest Invasion, understanding the nuances of each World Fighters side quest is essential for any player looking to dominate the leaderboards. From the starting island to the depths of Zone 6, here is everything you need to know to optimize your fighter's journey.
Overview of World Fighters Side Quests
Side quests in World Fighters Simulator function differently than your standard main-line progression. While main quests guide you through the zones, side quests are often tucked away in corners of the map, requiring players to explore thoroughly. These quests are designed for long-term progression, often requiring thousands of kills or specific RNG-based drops.
The 2026 update introduced several features that make these quests more manageable. The most notable is the improved quest tracking UI and the "Auto-Claim" toggle. Once you accept a quest from an NPC, you no longer need to return to them to receive your reward—the game will automatically apply the bonus to your account the moment the final requirement is met.
| Quest Category | Typical Requirement | Primary Reward | Difficulty |
|---|---|---|---|
| Early Game | 750+ Enemy Kills | Power Multipliers | Easy |
| Mid Game | 5,000+ Boss Kills | Haki/Stat Boosts | Medium |
| Endgame | Secret Units/Wave 25 | Unique Abilities | Hard |
Warning: Some side quests require "Secret" units or bosses. These have low spawn or drop rates, so prepare for extended AFK sessions or high-luck builds.
The First Step: Island One Power Quest
The very first World Fighters side quest you should encounter is located on the starting island. This NPC is essential for beginners because it provides a foundational power multiplier that affects all future gains.
To find this NPC, look for the first major building complex near the spawn area. Instead of following the main path toward the next island, head inside the designated quest building. The NPC inside will task you with defeating a specific set of enemies 750 times. While this may seem like a steep climb for a new player, the reward—a permanent 1.5x Power multiplier—is one of the most efficient upgrades in the early game.
Strategy for 750 Kills
- Equip Multi-Hit Units: Use fighters with AoE (Area of Effect) attacks to clear groups of enemies simultaneously.
- Auto-Clicker Setup: If playing on PC, positioning yourself between two spawn points can double your kill rate.
- Focus on Speed: Don't worry about high-damage units here; high-attack-speed units are more efficient for low-health mobs.
The Coliseum and Kaido's Challenge
As you progress toward the mid-game, you will encounter a significantly more difficult World Fighters side quest located near the Coliseum area. To reach this NPC, head to the first island and follow the right-hand path. Continue straight past the initial training zones, take a left at the fork, and proceed toward the circular Coliseum structure. The NPC is tucked away in the surrounding area, often overlooked by players rushing toward the boss arena.
This quest is notorious for its high requirements. You are tasked with using Rule Haki 1,000 times and defeating the boss Kaido 5,000 times.
| Requirement | Quantity | Recommended Method |
|---|---|---|
| Rule Haki | 1,000 | Set an auto-clicker on the Haki hotkey while training. |
| Kaido Kills | 5,000 | Join a private server to ensure boss respawn consistency. |
Tip: 5,000 Kaido kills is a massive undertaking. Most veteran players recommend an overnight AFK session with a high-DPS team to clear this within 8-12 hours.
Broly and the Secret Unit Quest
The third major side quest is located near the Secret Boss area. To find this NPC, navigate to the back of the map, past the primary boss gates. This quest is unique because it combines a high volume of "opens" with the requirement for a specific secret unit.
You will need to open 1,000 capsules (or units) and successfully obtain the Broly unit four times. Since Broly is classified as a "Secret" tier unit, his drop rate is incredibly low. This quest is designed for players who have already invested heavily in "Luck" stats or those who have access to Luck Potions.
How to Improve Your Odds
- Luck Potions: Always have a Luck III potion active before opening.
- Gamepasses: If you are a dedicated player, the "Super Luck" gamepass is almost mandatory for this specific quest.
- Fast Open: Use the "Fast Open" or "Triple Open" features to cycle through 1,000 units quickly.
Zone 6: Tempest Nation & Endgame Mastery
The final and most challenging World Fighters side quest currently available is found in Zone 6, also known as Tempest Nation. This area is intended for high-level players who have optimized their teams and reached a significant power ceiling.
To locate the NPC, enter Zone 6 and move straight toward the center of the city. Look for the largest building in the area; the NPC is hidden directly behind it. This quest requires you to defeat the secret boss "Guy" 5,000 times and reach Wave 25 in the Tempest Invasion game mode.
Tempest Invasion Tips
Reaching Wave 25 is a test of endurance and team composition. Unlike standard boss fights, the Invasion mode scales in difficulty rapidly.
- Balanced Team: Ensure you have at least one "Stun" unit to slow down fast-moving mobs.
- Placement Strategy: Place your highest DPS units at the corners where they have the longest line of sight on the path.
- Upgrade Priority: In-game, focus on upgrading your AoE units first to handle the early waves, then transition to single-target damage for the boss waves.

Maximizing Efficiency for Side Quests
Completing every World Fighters side quest is a marathon, not a sprint. To ensure you aren't wasting hours of playtime, follow these efficiency rules:
- Stack Quests: Always check if a side quest requirement overlaps with a main quest or a daily challenge. If you need to kill 5,000 bosses, wait until you have a "Slayer" daily quest to double your rewards.
- Movement Speed: Invest in movement speed items or mounts. Some NPCs are far apart, and the travel time adds up over dozens of trips.
- Community Servers: Use community Discord servers to find "Kill Groups." Farming 5,000 kills is much faster when four players are attacking the same boss.
| NPC Location | Main Requirement | Reward Tier |
|---|---|---|
| Zone 1 (Inside) | 750 Kills | 1.5x Power |
| Coliseum Path | 5k Kaido Kills | Haki Mastery |
| Secret Boss Area | 4x Broly Units | Secret Luck Boost |
| Zone 6 (Behind Building) | 5k Guy Kills / Wave 25 | Endgame Aura |
FAQ
Q: Can I do multiple World Fighters side quests at once?
A: Yes, you can have multiple side quests active simultaneously. It is highly recommended to pick up every quest you find so that your progress is tracked while you work on other objectives.
Q: What happens if I accidentally sell a unit required for a quest?
A: The quest tracks the acquisition of the unit, not the possession. If you get Broly four times, it will count toward the quest even if you delete or fuse them later. However, it is always safer to lock your secret units until the quest is officially marked as complete.
Q: Are the rewards from side quests permanent?
A: Yes, the power multipliers and stat boosts gained from side quests are permanent additions to your character. They do not reset when you move to a new zone or when the game updates, making them some of the most valuable investments in the game.
Q: Why isn't my kill count increasing for the Kaido quest?
A: Ensure you have the quest actively accepted in your quest log. If the counter still isn't moving, try re-logging or checking if you are attacking the correct version of the boss. Some quests require the "Elite" or "Secret" version of a boss to count.
