Ultimate Secret

This story is a key part of the Ultimate Marvel universe, specifically following events established in other Ultimate titles. While it tells a self-contained narrative, understanding the broader context of the Ultimate line enhances the reading experience.

Warren Ellis is known for his work on 'The Global Frequency,' and 'Ultimate Secret' shares some thematic DNA with his broader exploration of clandestine organizations and global threats. However, it is firmly set within the established Ultimate Marvel continuity, distinct from his creator-owned projects.
