Copen is a lone wolf who is a part of neither QUILL nor Sumeragi. He is, however, known for bearing a deep loathing for the Sumeragi Group and all Adepts in general. He believes that Adepts are a threat to world peace that will eventually subjugate anyone who is not an Adept, and thus, Copen has made it his mission to destroy Adepts at all costs.
Although Copen himself has no Septimal powers, he is a brilliant scientist and incredibly skilled fighter on par with the best Sumeragi has to offer. Utilizing septimosome that he has stolen from defeated Adepts, he crafted battle gear that replicates septimal powers, making him a formidable foe for even the most powerful Adepts.
