Dylan (Jason Marsden) is one of Betty's classmates. Tall, athletic, and intelligent, he appealed to just about every girl in school but was interested in Betty because of her interest in science. This began a rivalry between Betty and Penelope over him, though Penelope soon lost interest when she found out he was a bit too geeky for her tastes. Betty has also lost interest in him when Chaz appears in Mission: Earth, and he is only seen in cameos since. However, Dylan will finally have a crush on Betty again in the show's revival onward.
