Rise of the Brave Tangled Dragons, frequently abbreviated as RotBTD or simply 'The Big Four,' represents one of the most enduring crossover fandoms on the internet. It unites four protagonists from different DreamWorks and Disney films—Jack Frost (Rise of the Guardians), Merida (Brave), Rapunzel (Tangled), and Hiccup (How to Train Your Dragon)—into a single, cohesive team. Emerging in the early 2010s across Tumblr and DeviantArt, the meme reflects a collective desire for a massive animated cinematic universe. Usage of this template typically involves fan-made 'Modern AU' scenarios, shipping debates, or nostalgic tributes to the era of 3D animation that defined a generation of fans. It remains a powerful symbol of how community creativity can bridge the gap between competing movie studios.
