This suggests formative years filled with immersion in these media, laying the groundwork for his future creative endeavors.

Before achieving mainstream success, Toby Fox was active in the "EarthBound" community, creating ROM hacks. These were modifications to the original game that often involved new storylines, characters, and gameplay mechanics. This early experience provided him with invaluable experience in game design, programming, and storytelling, skills he would later leverage in his own independent projects. He was already honing his craft, learning to manipulate existing systems to create something entirely new.

Toby Fox began contributing music to Andrew Hussie's popular webcomic "Homestuck". His eclectic and energetic compositions quickly gained a following within the "Homestuck" fandom. This collaboration significantly boosted his visibility and provided a platform to experiment with different musical styles and genres. "Homestuck" exposed his talents to a large online audience, establishing him as a composer to watch.

Toby Fox independently developed "Undertale", a role-playing video game with a unique combat system that allows players to choose pacifist solutions. He handled the majority of the game's creation himself, including writing, composing the soundtrack, and designing the gameplay. The game was initially funded through a successful Kickstarter campaign, reflecting a strong belief in his vision from early supporters. This period was a crucial testament to his dedication and singular vision.

"Undertale" was released to critical acclaim, praised for its innovative gameplay, memorable characters, emotional storytelling, and exceptional soundtrack. The game quickly became a cult classic and garnered a massive online following. "Undertale"'s success established Toby Fox as a major force in the indie game scene and earned him numerous awards and accolades.

Following the immense success of "Undertale", Toby Fox remained relatively private but continued to contribute to other projects. He created music for the "Pokémon Sword and Shield" games, demonstrating his continued involvement in the wider gaming industry. He also focused on maintaining and updating "Undertale" and engaging with its passionate community.

Toby Fox surprised fans with the release of the first chapter of "Deltarune", a new project described as not being a direct sequel to "Undertale". The release was unexpected and generated immense excitement. The demo demonstrated an evolution in his game design, with more complex battle mechanics and a similarly compelling narrative, building anticipation for future chapters.

Toby Fox released "Deltarune" Chapter 2. Chapter 2 was released for free, like Chapter 1, with the promise that the following chapters would come at a price. While the world had to wait a few more years, many fans enjoyed finally getting to continue the adventure. The game had a significant impact on the gaming community again, receiving high praise for its story, characters, music, and humor. It generated immense discussions and fan theories, similar to those surrounding "Undertale".
