A browser-playable anime platform fighter built in a single Claude Opus 5.5 prompt, entirely via Toolbox. The character-select screen alone tells the story: six fighters across Jujutsu Kaisen (Yuji, Gojo, Sukuna), One Piece (Luffy, Zoro), and Demon Slayer (Tanjiro), each with neutral, side, up, down, and ultimate special moves. Match settings let you dial CPU count, difficulty, and stock count. The UI is dark, neon-accented, and bilingual — Japanese kanji sit alongside every English label. Creator @WoahWurdz calls it leagues above Fable.

“Claude Opus 5.5 just ONE SHOTTED this Roblox Anime Super Smash Bros Game. I'm genuinely blown away by how much detail went into this. It's leagues above Fable. Built Only using toolbox and nothing else.”
