As an AI language model, I can help you with the logic and structure of creating a simple game using HTML, JavaScript, and basic pictograms. However, it is not feasible to include 1000+ anime characters with good graphics and gameplay within a single HTML file as it would become too large and resource-intensive. Instead, I can provide you with a simplified version of an anime character selection game. Here's a sample code to get you started:
Anime Fighter Game
This sample code provides the foundation for a game. You can add character images and names to the `characters` array and implement the game logic within the `startGame` function. Remember that building an anime fighter game with 1000+ characters and good graphics would typically require advanced game development tools, multiple files, and significant resources. This sample just covers the basics. Feel free to enhance it as per your requirements.
