Treasure chest

A treasure chest (宝箱), also known as treasure box, is an object found throughout ruins in the Mega Man Legends series, and are also present in Mega Man & Bass. They usually contain items, but sometimes it may have a trap or be an enemy in disguise.

Mega Man Legends series
In most appearances they are simple treasure chests that can be opened by interacting with them, but inside the Cardon Ruins is a green chest that can't be opened normally due to being rusted. To open it, MegaMan Volnutt needs to break the floor under the chest so it will fall and be carried by the conveyor belt below, being destroyed in the end of the path, its content popping out afterwards. The chests in The Misadventures of Tron Bonne are golden, and some are locked, requiring a key to be opened. In Mega Man Legends and Mega Man Legends 2, some chest are Trap Boxes that release bombs when opened. Also, some chests are Mimics in Mega Man Legends 2.

Mega Man & Bass
Treasure chests appear in Ground Man's stage, Pirate Man's stage, and King Stage 2. They can be easily destroyed by Mega Man or Bass, revealing their content, but some are Kamikamins that will attack the player if approached or attacked.
