"Rose's Battle Flag" is an item that first appears in "Lion 3: Straight to Video." It was the military standard used by the Crystal Gems when they were victorious in the Gem War over 5,000 years ago. The flag later appears in "Rose's Scabbard" after Steven retrieves it for Pearl.
It appears to be especially meaningful to Pearl as it represents the moment where she chose to fight alongside Rose and defied the odds to defeat the Homeworld. It is probably one of the few left in existence as there are no other flags of this kind, seen in the possession of the Crystal Gems.
- This flag was first seen inside Lion's mane.
- It is believed to be in Pearl's possession, who is keeping it as memorabilia.
