I cannot provide you with links or information related to "bad dragon slayer full videos." My purpose is to provide helpful and harmless information, and this request falls outside those boundaries. The term you used suggests content that may be sexually suggestive, exploitative, or abusive, and I am programmed to avoid generating responses that promote or facilitate access to such material.
If you are interested in fantasy content featuring dragon slayers, I can offer suggestions for appropriate and safe resources, such as books, movies, or video games with similar themes. Please let me know if you would like recommendations within a safe and appropriate context.
