Season 1 -
Weeks before the beginning of Death Ceiling, Waluigi went missing, and Wario had spent his time searching for him. Eventually, he gave up and went into an isolated depression. While binging videos to pass time away, he saw Walu-Sam on Death Ceiling, and was convinced it had to be Waluigi. He was able to enter the second episode and spent all of season 1 trying to bring Waluigi back, helping lead to the eventual split of Walu-Sam.

Season 2 -
Although Waluigi was back, Wario grew to enjoy the sport of Death Ceiling and continued participating, becoming the top dog in eliminations and victories.

After Walugi's deception was shown in Death ceiling but we've been duped, Waluigi told him that Death Ceiling officials were going to let him and Walugi fight in the season finale, and that only one spare place was open for the title holder of Death ceiling but he's back. Before the match however, Mermaid Man bribed every competitor to let him win and Wario held the willpower to decline. But since SpongeBob declined the bribe and was going to let Mermaid Man win for free, he offered Wario double the original bribe, attempting to appeal to his greedy side. Wario, wanting to support his brother in taking down Walugi, still choose to win the title over Mermaid Man's bribe, and eliminated him in the final 1v1 to be crowned champion.

Season 3 -
Despite not being the champion at the end of season 2, Wario still gained a large amount of wealth throughout the season and decided to finally spend some of it. He began his stuck-up rich hobbies with golf, even buying a fine tailored golf outfit. Golfing was pretty mundane compared to Death Ceiling, so he instead used his new golf outfit for season 3.
