Small Cosmic Clones behave like the Cosmic Clones of Super Mario Galaxy 2, matching the player character's movements and actions in the course. If the player character stops moving and makes contact with a Small Cosmic Clone, the player's character is damaged. However, Small Cosmic Clones do not appear in groups, nor do they dissipate when touched. Mario or Luigi can defeat Small Cosmic Clones by touching them while in his invincible form or by touching the course's Goal Pole. They will also be defeated on contact with a Poison Mushroom. They give three coins upon defeat. Upon Mario or Luigi reaching a certain area (normally the course's halfway point), the Small Cosmic Clone disappears. If the player character leaves that area, the Small Cosmic Clone appears again, even if it has been defeated with a Super Star.
Big Cosmic Clones have a much larger size, a lower-pitched voice, and the ability to destroy Brick Blocks and pillars. Big Cosmic Clones appear once the player reaches a certain point in a stage and mimic their movements. They can be defeated in the same ways as Small Cosmic Clones: by touching the course's Goal Pole, touching them while invincible, letting them come in contact with a Poison Mushroom, or crossing a point they cannot. The player receives ten coins after defeating them by using the former three methods, as opposed to three coins from a Small Cosmic Clone. They otherwise behave the same as Small Cosmic Clones, and they still resemble Small Mario.
The contemporaneous name for each language is listed first. Subsequent names are listed in chronological order for each language, from oldest to newest, and have the media with which they are associated in the "Notes" column. Names exclusive to localizations of the Super Mario Bros. Encyclopedia are not prioritized due to concerns about circular reporting, and are only listed first for their respective languages if they are the only ones available.
