He also punishes Sherri and Terri for tormenting Lisa. Another curious example of his "good side" is with Martin, a boy whom Nelson picks on perhaps more so than any other kid in town. Despite the utter cruelty, there are occasional hints that Nelson does not harbor any real hatred towards Martin and only does so to maintain his 'tough guy' reputation. In "Dial 'N' for Nerder", when it is believed that Martin has died, Nelson endeavours to learn the truth and find Martin's killers. When it is revealed that Martin is alive, Nelson mocks and punches him, but also states that he is glad Martin is not dead. In this same episode, however, when Lisa tries to bribe him to not rat her out by offering to get back together with him, he rejects it. In another episode, it is revealed that both Martin and Nelson went to space camp, and that Nelson was a loyal officer to Martin. (See "I'm Spelling as Fast as I Can")
