As an AI text-based model, I can assist you in providing a basic outline for a simplified version of the game you described. However, developing a fully functional 3D fighting game with complex animations and textures would be beyond the scope of a single HTML file and the capabilities of a text-based conversation. Nonetheless, I'll provide a sample structure for a basic turn-based fighting game using JavaScript and pictograms. Please note that this is a simplified version and you may need further development to make it a complete and engaging game.
Note that the code provided is a basic outline and lacks specific functionality and details such as character movements, attack animations, health systems, and other gameplay mechanics. Developing a complete 3D fighting game requires a more comprehensive approach, including the usage of libraries, frameworks, asset management, and more.
