Luigi is the younger twin brother of Mario and a hero in the Smash Fighters Z series.



Luigi is very timid and rather cowardly, and therefore ends up becoming frightened and discouraged from fighting, much to his teammates' dismay. He often teams up with others whenever he gets his momentary bursts of courage, mostly for team attacks or assists. He could be often seen as comic relief in the series, due to his fearful nature and his antics.

Luigi is also considered to be compassionate and shows great concern for his brother, often helping, healing and reviving him when he is injured, or saving him from a fatal blast. When provoked, Luigi has been shown to be a powerful fighter who does not hold back, as seen when he relentlessly charges at Bowser with a few hits during the Mecha Sonic Saga. He is normally the one who is the most frightened of major threats.
