Waluigi is one of the Fun Pack characters in LEGO Dimensions 2: The Rise of Enoch, from the Super Mario franchise.
Waluigi is a recurring character found in the Mario series who was made to rival Luigi. Waluigi mainly appeared in spin-off games such as Mario Tennis and Mario Party 3. Waluigi is known to be Wario's partner ever since Waluigi made his first appearance in Mario Tennis for the Nintendo 64 and was voiced by Charles Martinet ever since. Waluigi also appeared along with Wario and Luigi in Super Mario Advance games as a palette swap of Mario. He has also appeared in every Mario Party game since Mario Party 3 came out in 2001.
The details of Waluigi's past are unclear since he has no confirmed background, although he was evidently been antagonizing the Mario Bros., especially Luigi, for quite some time before his debut as seen in the opening of Mario Tennis, where he and Luigi confront each other.
