Step 21: For a more finished, inked look, carefully draw over the final sketch lines with a pen or marker. Wait for the ink to dry, and then get rid of every pencil mark with an eraser. You now have a finished inked drawing of the Riddler, Batman's enemy from Batman: The Animated Series! You can stop here or continue to the final step to complete your Riddler drawing.
Final Step: For a completely finished Riddler drawing, you have to color it. You can use markers, color pencils or even crayons! Color his hat green and leave the band white. His mask is purple, and his hair is orange. His skin is peach-colored, but if you don’t have peach, improvise and use yellow-orange or light brown. Experiment! That’s it! You now have a completed drawing of the Riddler, Batman's enemy from Batman: The Animated Series.
