Mario is the #1 crime boss in the world and the main antagonist in Season 2 and again in Season 6. Even though his voice is similar to Sonic (only in an Italian-mafia accent), he was voiced by Clint Gage (who also voiced the narrator).
After Sonic was told by Tails that he had to borrow money to bail him out of jail in "Ice Hockey", he ends up working for Mario to work off his huge debt. In "Toad", Mario tells Sonic to kill Toad because he's having face sex with Birdo rather than doing his job which is watching the princess. In "Angry Birds", he orders Sonic to kill "a group of pissed off birds that have gotten a little too popular lately". In "Double Dragon", he asks Sonic to kill off the brothers from Double Dragon but he ends up failing the job due to poor assistance from Eggman and Earthworm Jim. In "Frogger", Mario sent Sonic to kill Frogger because he has been holding up trucks for his drugs. He also sends Luigi along with Sonic to keep an eye on him so he doesn't mess up, but Luigi licked him, and get's killed by a bus. Not only that, but he forgot to kill Frogger. In "Donkey Kong Country", Mario gets Sonic to go get some TNT barrels from Donkey Kong Country because he feel like blowing up some worlds. Sometime after Sonic and Tails leave, Frogger shows up at Mario's office and tells him what happened. Soon he pursues Sonic to Donkey Kong Country and is ready to kill him but he get's knocked into a cliff by Candy Kong. Mario survives the fall, however, and calls up all of his goon friends and most of Sonic's enemies to kill him in "The Battle" story arc, until he and most of Mario's allies get killed.
In "The Battle Part 02", most of Mario's allies get killed and he ends up dead after Sonic knocks him in a pit of spikes. His last words were "If you see the princess, tell her....tell her I said....she's a bitch!". Due to his death, Sonic is made the new crime boss.
Despite his death, Mario was mentioned alot in Season 3. In "Tapper" Tails tells the bar tender that Sonic took over Mario's buisness. In "Link" because Sonic and co. had no idea how to run a mob buisness, Tails suggests that, since Peach was close to Mario, she could give them some tips. In "Peach" Sonic reveals to Princess Peach that along with Bowser, Mario was killed and he wanted him to tell her that she was a bitch. It was also revealed that Mario was close to another Princess named Princess Potato. It was revealed in "Casino Zone: Part One" that Mario was going to rob Casino zone, and he'd tell Princess Potato everything while they were..."doing it". If he was alive and still the crime boss, it's possible that the same thing that happened to Sonic in Casino Zone would've happend to him. Mario was mentioned by Sonic in "The War: Part One". Vader challenged Sonic to a battle, but Sonic didn't want to, because he'd already fought with Mario, but agrees when Vader frees Dominique Wilkins from the carbonite. Mario made a cameo as a ghost in "The War: Part Two" where he along with the ghosts of Louie Anderson, and Darth Vader were smiling and congratulating Sonic on his victory. This is a parody from star wars. His corpse was seen in "It's On" and Sonic jumped on him and his arm fell off just to avoid falling into the spikes, then Mario's corpse was seen again in Movie Magic where Kirby swallowed him and take his powers so he can play as him.
Mario was mentioned in Season 5 "Shadow". Sonic's old rival Shadow the Hedgehog to entered StarFox with a bag full of stolen TVs, xboxs, weed, beer, and the chaos emeralds. The cops were on his Tale, but Tails had an idea that involved bringing Mario back to life by having Sonic using the Chaos emeralds and becoming Super Sonic.(After taking out the cops of course) Then they would have Mario become mob boss again so He could use his mob-ties to sell the weed which would make Sonic's group rich and powerful. Unfortunately Sonic only became super sonic to get the xbox to work, and the cops Shot shadow in the back, therefore forfetting Tails's plan.
In Season 6 "Thunderhead" after Sonic had changed the past again and defeated Thunderhead in a Spin Dash contest, Princess Potato, now the president of the U.S.A., stole the epoch and went through time travel. It was shown at the end of her Speech that Mario was back and said "Guess whose back motherfuckers," much to Sonic's hatred. It can be assumed that Princess Potato must have picked Mario up around the time he was out to kill Sonic for messing up his buisness, killing Luigi, and the whole Bachelor Pad thing on his DVR. Mario will most likely appear again when he tries to kill sonic. "In Avengers" Mario hires bounty hunters to kidnap Sonic and bring him to him alive. The first group was an other failure, especially since Earthworm Jim killed them, so Mario hires the Avengers to do the job. IT goes well When sonic goes to hire them to protect him, Hulk grabs him and he, ironman and captain america take off with him leaving behind Catness, who gets treated like crap. In the next Episode "Return Of The Plumber" Mario kills Sonic. This action brings out world peace for some reason, he then uses the epic to go back in time, revive all his dead goons, then goes to take over the world. Unknown to him, Soniqua learned about this and set off on a journey to kill him. In "Soniqua Mad" Mario learns his allies are being killed by Sonic's Daughter, when she sent him the head of bowser, and set a trap using peanut butter and a cage. In the next episode "Flaming Bag of Poop", he's talking to Luigi, whose he probably brought back, about dinner and gets ready to kill Soniqua with lava. Unfortunately, it doesn't work, and Luigi ends up dying again. He gets really annoyed with Soniqua when she keeps saying Avaccodo, and gives her some, but it fails. He then tries to kill her with Bullet Bowser; however, due to a prank Earthworm Jim, Tails, and Eggman set up, his base gets set on fire. As the heroes leave with Soniqua and Sonic's body, Mario escapes to the epoch, but he, along with the time machine, are blown up by Bullet Bowser. However, he survived, according to the Reset section on the Volume 6 DVD episode guide.
It was revealed in "Things Get Messy" that, for whatever Tails, Jim, and Eggman did, not only revied Sonic, but Mario had become a chicken farmer.
Unlike his game counterpart, Mario is cruel, coniving, and vengeful. He will do whatever it takes to eliminate his enemies and take over the world. His main goal in season 2, was a mob buisness that went well until sonic ruined it. Mario's very persistant. However, it seems that the only thing he cares about is Luigi as he was very angry when Sonic got him killed (Along with ruining his buisness and putting bachelor pad on his DVR) which triggered his mission to kill him in the first place, and even brought his younger brother back to life In "Flaming Bag of Poop" and was annoyed when Soniqua killed him.
