I couldn’t verify the exact Roblox UGC item ID for Black & Gold Legionnaire Commander Bottom from the sources I found, so I can’t give you a reliable ID without guessing. The closest verified result I found was Blue & Gold Legionnaire Commander Bottom on Roblox, which suggests the item exists in that Legionnaire Commander line, but not the exact black-and-gold version you asked for.

What I found

  • Empyror is the creator group associated with the item line.
  • A Roblox catalog page exists for Blue & Gold Legionnaire Commander Bottom with item ID 13235631805.
  • I did not find a confirmed public page for the exact Black & Gold version in the available results.

Best next step

If you’re trying to use it in an avatar app or game, the safest move is to search the Roblox catalog or Empyror’s item listings by the exact name and creator, since UGC item IDs are the numeric part of the catalog page URL.
