Command Block

"Note the blocks that appeared above you. Use those fellows to pick what you will do!"

- Toadsworth

Command Blocks (sometimes spelled in lowercase as command blocks) are blocks in the Mario & Luigi series. They appear during battles, so Mario, Luigi, Baby Mario, Baby Luigi, and Paper Mario can jump under or Bowser can punch under the block that they want to choose. The block they choose determines the move they want to do.

In some games, Command Blocks can be disabled by certain enemies and bosses temporarily (like Popple and Boos in Mario & Luigi: Superstar Saga and Mario & Luigi: Superstar Saga + Bowser's Minions, and Kamek and Paper Kamek in Mario & Luigi: Paper Jam), or permanently for the rest of the battle, some examples being Shrowser's battle in Mario & Luigi: Partners in Time, Thunder Sass's battle in Mario & Luigi: Dream Team (except the items Command Block and the hint Command Block if the player gets a Game Over), and Ludwig's battle in Mario & Luigi: Superstar Saga + Bowser's Minions. In Mario & Luigi: Paper Jam, when Mario, Luigi, and Paper Mario are locked away in Twinsy Tropics Dungeon, a team of Hammer Bros confiscate the trio's Command Blocks to hinder their fighting capabilities. The three must defeat the Hammer Bros using a combination of First Strikes and counter attacks in order to regain the Command Blocks.

In volume 35 of Super Mario-kun adapted from Mario & Luigi: Partners in Time, Luigi and Baby Luigi hit the flee Command Block to run away from a Snoozorb, much to Mario's irritation, therefore breaking the fourth wall.
