Luigi is one of the main characters and main protagonists of the Mario and Plush Friends series. He is the brother of Mario, who is older yet shorter than Luigi. Just like Mario, he is friends with everyone, but at times he can be enemies with his friends, especially Mario, Red, Hoppy, Zippy, and Matilda. He is cowardly, somewhat strong, fast, carefree, lazy, energetic, and friendly. He likes pizza, too many parties, which is why he's so energetic, and playing with Banana Joe. What he dislikes is Mario telling him what to do, running out of pizza, being broke, and Chilly constantly saying he might melt.
