A comic book omnibus is a first-time collection of comics and tie-in issues, usually by the same writer and artist. This is a trade that collects comics and series that were never in a collection before. So, you may get the first 40 issues of the series, two annuals, and five tie-in issues, and the origin issue of the character from decades ago in a 900-page trade, for example.
Many modern and casual readers are intimidated by the decades of canon and backstory of certain comics. An omnibus collects vital stories and issues, and stories going back years or decades. You could learn the most important stories and moments of a specific character with the right omnibus. So, if you want an omnibus for yourself or as a gift for someone else, here are 10 that I highly recommend.
