One-Punch Man x MapleStory Event Guide

March 19, 2026

With the release of MapleStory GMS Patch V267, a new event featuring a cross over with the popular manga series One-Punch Man has begun. Play in a temporary special world as Saitama for exclusive rewards you can claim on your main.

Many of the quests for this event are only available in the Special World. You can select it from the main menu when you login to MapleStory.

There you'll be able to create a new character called Saitama. All other classes in this world are locked.

Special World

Saitama

In the special world, you'll only be able to create a Saitama class. You'll start at Level 10 with just a couple of skills and need to level up to progress.

This world has the following server rates:

  • +1,000% EXP until Level 250
  • +500% EXP after Level 250
  • 10x Mesos Rate
  • Increased Monster Spawn (frenzy spawn)
  • Maps are instanced where monsters are Level 60+

Once you reach Level 200, you can claim a Justice Enforcement Booster each day. You can also complete all Arcane River quests by completing the quest Maple World at Last.

All characters in the Special World will be deleted once the event is over.

You'll also have access to the Slime's Meso Shop where you can buy a bunch of useful items to help with progression (see below).
