Gallery Pieces in My Hero Ultra Rumble are a cosmetic currency you use to unlock artwork that can be used as loading-screen wallpapers; they do not affect gameplay or power at all.

What Gallery Pieces Actually Do

  • You spend Gallery Pieces in the Gallery menu to complete illustration “puzzles” made of panels.
  • When you finish an illustration, it becomes a loading screen / wallpaper option for your matches.
  • They are purely cosmetic : no stats, no damage buffs, no gameplay bonuses.

In other words, they’re basically a collectible currency for unlocking art and customizing how your game looks between matches.

How They Work (Step‑By‑Step)

  1. Earn Gallery Pieces
    • You get red/green/blue (and sometimes pink) Gallery Pieces from missions, season pass levels, and chest drops in matches.
  1. Go to the Gallery
    • From the Main Menu , open Menu → Gallery to see the available illustrations and how many panels each needs.
  1. Use Pieces to Unlock Panels
    • Select an illustration, choose Use Pieces , and spend your Gallery Pieces to clear the blank tiles/panels.
 * Different pictures can require different amounts or colors of pieces.
  1. Set Them as Loading Screens
    • Once an image is fully cleared, it joins the pool/rotation of loading screen images , similar to banners or wallpapers.

Forum‑Style Take

On community forums, players usually summarize Gallery Pieces as “wallpapers, that’s it,” sometimes joking that once you’ve unlocked every gallery picture, you’d rather get tickets or other rewards instead.

TL;DR

Gallery Pieces are only for filling out the Gallery art and turning those completed images into loading-screen wallpapers; they’re a style/customization collectible, not a gameplay resource.
