How to Get Flash in Pokemon Infinite Fusion
If you’re stuck in a dark cave wondering how to get Flash in Pokémon Infinite Fusion, you’re not alone! Flash is a crucial move (or item) that helps you light up dark areas like Rock Tunnel and without it, progressing through the story can feel frustrating. In this fully detailed guide, we’ll walk you through exactly what Flash is, how it works in Pokémon Infinite Fusion, and most importantly how and where to get Flash or its alternate the Lantern.
What is Flash in Pokémon Infinite Fusion?
Flash has traditionally served as HM05 (Hidden Machine 05) in classic Pokémon games, allowing players to light up dark caves and tunnels for easier navigation. In Pokémon Infinite Fusion, an innovative approach is taken where the Lantern item replaces the need to teach Flash as an HM move. This change creates an opportunity for players to enhance their experience by focusing on obtaining the Lantern, which not only illuminates dark areas but also preserves a valuable move slot on their Pokémon. By embracing this alternative, players can enjoy a more versatile strategy while exploring the game’s environment.

Why Flash (or Lantern) Matters in Pokémon Infinite Fusion
In Pokémon Infinite Fusion, caves like Rock Tunnel, Cerulean Cave, and several custom fan-made dungeons are completely dark without light.
Walking blind can:
- Slows down your progress
- This leads to unnecessary trainer battles
- Increases the chance of missing key items
So, getting a light source is essential. Just be sure to learn the best ways to acquire it and how to use it effectively.
How to Get Flash in Pokemon Infinite Fusion In Detail Guide
In Infinite Fusion, “Flash” isn’t just a move, it’s a function that lets you light up pitch-black areas like Rock Tunnel, Seafoam Islands, or special caves. You’ll need Flash (or its alternatives) to see where you’re going, find hidden items, and avoid annoying wild battles.
1) HM08 Flash – A traditional HM move
2) The Lantern – A reusable item that replaces Flash without needing a Pokémon move slot
Let’s break both down.
How to Get HM08 Flash in Pokémon Infinite Fusion
Visit a Hotel
Hotels are located in various major cities, including:
- Vermilion City
- Lavender Town
- Celadon City
- Cerulean City
- Fuchsia City
- Saffron City
- Cinnabar Island
Use the elevator or stairs in each hotel to reach the top floor, where the NPCs and the scientist are located.
Talk to NPCs and Accept Side Quests
Once you’re on the hotel’s top floor, you’ll see multiple NPCs offering side quests. These tasks are usually quick and varied:
- Find or deliver lost items
- Talk to specific characters
- Solve small puzzles or riddles
- Locate certain Pokémon
Important:
These quests can be completed in any hotel and in any order, progress is shared across all locations.
Complete at Least 5 Side Quests
After completing five total hotel side quests, talk to the Quest Scientist. You’ll usually find him standing near the stairs or elevator on the hotel’s top floor.
He tracks your quest progress. If you’ve helped 5 different people, he will recognize your efforts.
Receive HM08 Flash
Once the scientist confirms you’ve helped 5 people, he’ll reward you with HM08 Flash. You can now teach it to a Pokémon to light up dark areas.
Quick Tips:
- You do NOT have to complete all quests in the same hotel.
- You can mix and match quests from different cities.
- Revisit the Quest Scientist anytime to check how many quests you’ve completed.
- Some quests are faster than others — prioritize the quick ones to speed up the process.
How to Get the Lantern in Pokémon Infinite Fusion
Once you have HM08 Flash, you can go a step further and unlock the Lantern, a superior alternative that works automatically and doesn’t take a move slot.
How to Unlock the Lantern (Step-by-Step)
Help 10 NPCs Across Hotels
Continue completing hotel side quests. Once you have helped a total of 10 people (across any hotel), return to the same scientist who gave you HM08 Flash.
Receive the Lantern
After verifying that you’ve completed 10 side quests, the scientist will reward you with the Lantern, a key item that automatically lights up all dark caves and areas when you enter them.
No need to teach it, no need to activate it – it just works.
