Niles appeared to be coolheaded and rebellious, given how he often ends up in detention and enjoys picking on others, especially Melony due to her naivety and goody two-shoes personality, but is also sarcastic and obnoxious as he makes jokes about politics (making him an absolute anarchist) and has no problem giving openly rude opinions to others when he feels like it, such as when he tells Mario his speech in the cafeteria was terrible despite being the only one to cheer.
