Copy Block

The Copy Block is a block appearing in Mario & Luigi: Paper Jam created by the Paper Toads that allows Paper Mario to clone himself. After saving the eight Paper Toads in Peach's Castle, they and Toadette make the Copy Block and give it to Starlow. Afterwards, while battling with the Paper Goomba in Sunbeam Plains, Paper Mario floats down onto the battlefield and Starlow gives him the Copy Block. Every time he gets hit, he does not take any damage, but rather loses one or more clones, depending on the strength of the attack. Paper Mario only starts accumulating damage when he is the sole copy. During the Paper Petey Piranha boss fight, he steals the Copy Block from all the Paper Marios

There is a special Battle Card that enables Paper Mario to create eight clones after using it. Additionally, a rank bonus allows Paper Mario to increase the number of maximum clones he can create by two permanently.
