Along with Mertle Edmonds from Lilo & Stitch and Nabiki Tendo from Ranma 1/2, Steve has served as an influence for the rival villains in the films of independent filmmaker and producer Ms. CMZ, such as the self-centered Madame Chairbird (Sesame Street MVs), narcissistic Yank the Jack Russell Terrier (Y.T.J.R.T.), the arrogant customer Tatewaki Kuno in No Ranmavations (2008), and the greedy, manipulative boxing announcer in CMZ's The Little Panda Fighter (2018).
