Marvel & DC Omnibus

Deadpool: Beginnings collects the mercenary's earliest appearances — from his New Mutants debut through his initial solo outings — before the character had fully evolved into the fourth-wall-breaking icon he would become. Fabian Nicieza and Rob Liefeld created a character who was initially played fairly straight as a threat, and watching the early material shows how gradually the humor, self-awareness, and meta-commentary were layered onto what began as a fairly conventional 90s assassin concept.
