"Make a D and character" is a bit ambiguous. Are you asking about:
* Creating a character in a game like Dungeons and Dragons (D&D)? If so, you'll need to tell me more about the game system you're using, what kind of character you want to create, and what information you need help with.
* Designing a "D" character in a visual medium like drawing or graphic design? If so, I can provide tips and ideas on how to create a visually appealing character with the letter "D" incorporated into its design.
* Something else entirely? Tell me what you have in mind, and I'll do my best to help!
