My Lex Luthor was made using a Clark Kent. I took an exacto knife and gave him a hair cut and some plastic surgery. A coat of paint and done.
Bruce Wayne here got a little trim and chin-job like Lex, followed with a paint job and Clark Kent got a lot richer.
My final presentation today is my repaint of the Batgirl figure. I wanted her to look more like she did in her initial appearances. I added a waist bag and then gave her several coats of paint. The yellow on the inside of her cape took several coats. I first painted it white as a primer and then did three full coats of yellow before I got good enough coverage.
