James Stobux "Jimmy" Ronaldson, better known by his online alias MrBux, is a Robloxian BloxTuber, online personality, entrepreneur, and philanthropist. First, he became a young billionaire. He is known for his fast-paced and high-production videos, which feature elaborate and paid challenges and large giveaways, in which he calls them internally as "donation videos for my game winners". With over 259 million subscribers, he is the most-subscribed individual on BloxTube and the second-most-subscribed channel overall. MrBux has hired many Robloxians to make his videos. However, he is controversial in which his elaborate and paid challenges and large giveaways have sparked some questions as to the truth of his contests.

Criticism:
In 2024, MrBux would announce his new food line known as Runchly. Robloxians were getting unhappy with it due to a issue with it being moldy and triggering major allergic reactions in Robloxians.
Further criticism would start when one of his workers he fired blew the whistle on MrBux. In a video, he claimed MrBux scams and frauds Robloxians.
One of his employees was arrested in Bloxburg for harassing other celebrities.
In 2025, he would face major lawsuits after giving his Runchly meals away to members of the Robloxian government, Furry Headquarters, and United Roblox Countries ( there was a large amount of others but those two were the worst affected ) for causing many Robloxians of those agencies to receive severe food poisoning from it. In Mr. Bux v. Robloxia, Furry Headquarters, and United Roblox Countries (2025), he was sued for the hospital bills for severely food poisoning many Robloxians.
