The Blue TerrorEdit
Gonzo's first appearance is in The Blue Terror, as the main antagonist, Gonzo fights Mario and Luigi, but ends up losing. He comes back, more powerful, and defeats Jack and murders Kermit, but the Mario Bros, with help from Mickey Mouse, manage to defeat him by throwing him in the bowl of lava he intended to kill Mario and Luigi with, however, in a post-credits scene, it's revealed that he had survived, though weak, indicating the third movie.
Return of the EhhsEdit
In Return of the Ehhs, Gonzo is Kermit's boss and the Behind-the-Scenes villain. All that you can see is his feet to conceal his identity, because he is either behind a blind or a book. He recruits The Ehh Guy and The YOU! Guy to defeat the Mario Bros. but Kermit defeats them.
The Rise of GonzoEdit
In The Rise of Gonzo, Gonzo returns, once again the main antagonist. The beginning takes place right after Mario's Rock Band Part 3, where Mario has run away from home, he is confronted by gonzo in Death Forest, in the form of the Band Director, and then reveals his true form. He then starts beating up Mario, easily dominating over him. Just as it seems Mario is done for, Mickey appears and knocks Gonzo away. Mario and Mickey run through the forest, with a furious Gonzo hot on their tail. Although Mario is still angry at Luigi and refuses to make up despite Mickey's pleas, Mickey resorts to using a Time Stone to open up a portal to the future. As they jump in, Gonzo arrives, but is to late as the portal closes. With Mario gone to the future, Gonzo sets his next plan into motion: to find and kill Luigi. Later, Mickey and Mario arrive 100 years in the future, which is decimated and destroyed thanks to Gonzo's power. After finding Toadsworth and Mickey's hideout, a prophecy reveals that, due to Mickey's interference, Mario has dissapeared, and Luigi, Jack Skellington and Bowser are looking for him. Gonzo confronts and kills them all. Sometime later, Gonzo had found a Fire Flower, a powerful item that grants the user fire based abilities. Gaining it's power, Gonzo uses his new found power to lay utter destruction to the Mushroom Kingdom, killing thousands of people and causing massive damage. Gonzo is later seen in the past, after Mario uses Mickey's Time String to go into the past. Screaming Mario's name in fury, Mario goes into the house, just as Luigi, Jack and Bowser are about to go looking for them. Mario and Luigi then emotionally reunite and apologize to each other. Mario then explains the situation and his plan to change the future. However, Gonzo arrives and busts in. Mario and Luigi escape out the back. Gonzo finds Jack hiding and forces him to tell where Mario and Luigi are. Though Jack refuses, Gonzo threatens to kill him, saying he'll turn [Jack] to ash. Jack mistakes this, thinking he'll be turned into Ash Ketchmup. Jack relents and tells Gonzo Mario's plan. Gonzo knocks Jack aside and gives chase to the Bros.
Future (Season 4)Edit
It is planned that Gonzo will be revived by Mrs. Stinkybutt, however as a mind-controlled undead sidekick, and will be back in his normal form, he will be one of the Secondary Antagonists of the season, however it's planned that he will somehow go back to normal and develop his new hatred towards Mario and Luigi.
