Bros. Item

Bros. Items are special items used by Mario and Luigi and their younger selves in Mario & Luigi: Partners in Time. Bros. Items are different from regular items in that they are used for attack (oftentimes a specialized Jump attack), and require at least two heroes to be alive when utilized (some Bros. Items only work with all the four heroes together, though).

They replaced Bros. Attacks from Mario & Luigi: Superstar Saga and are replaced by Attack Pieces in Mario & Luigi: Bowser's Inside Story.
