Mario

"'Tell me where the money is please and thank you or I will shoot you'"Mario was a contestant in the first season of Video Game All-Stars as a member of Team Eggman. He later returned to compete in the second season as a member of Triple Metal Dededes.

Personality
Mario is quite competitive, willing to do anything to secure a winning position, to an extent of revealing a darker side to his personality, which doesn't often sit well with other contestants.

Season 1 - Video Game All-Stars Island
Mario engages in small talk on the boat ride to the island in S1E1 - VGAS Kart Arcade GP, however he does not make any especially strong bonds with any other players. In the race, he attacks Mugman with a banana peel to get ahead of the others, but in the end he doesn't become a team captain. As K. Rool respects his offensive approach in the race, Mario is first picked to join Team Eggman, however the team's overall lack of coordination makes them lose the second part. Mario has no issue voting Pac-Man out.

In S1E2 - The Legend of VGAS, Mario gets to the top of the mountain relatively quickly, fast enough to be one of the seven to move on to the second part of the challenge. He notices the wave of enemies coming their way and is a strong help fighting them off. In the fight against Ganondorf, he is thrown against a wall, then with a lack of support from his allies, his team loses a second time. Mario decides to vote for Marisa, as he feels she doesn't help the team much, but K. Rool is eliminated instead.

In S1E3 - Catch Em' Fast!, Mario makes a point that he dislikes Sonic, due to their rivalry. He helps his team devise strategies to catch Sonic, though in all the confusion during the challenge he gets distracted by Team Squidbeak Splatoon's own plans. In the end his team wins, which he is happy with.

In S1E4 - Getting The Cash!, Mario's violent side is exposed during the challenge, as he steals a car and gets his hands on a gun, shooting at anyone who gets in his way. He makes it to the bank quickly and threatens the staff so he gets shown where the money is. Upon finding it, he steals as much as he can before making his escape. After shooting down a helicopter and driving through a wall to get to Banjo, he is slowed by Spyro and Gundham from the opposite team. The encounter makes him drop half of his money, but he still gets a decent amount in. Despite his efforts, Team Eggman loses, and while he makes an attempt to vote out Mugman, the vote ends up tying. He doesn't get as much money as Mugman in the tiebreaker, so he is eliminated.

He gets the opportunity to return in S1E8 - Star Return, however he is pushed out of Rise's ship, causing him to lose the contest. He is seen watching the finale, though he does not clearly root for either side. He leaves via warp pipe, considering attempting a second season.
