The ending of the comic series varies greatly depending on the specific series in question. For instance, the ending of "The Walking Dead" comic series involves the main characters finding a new home and attempting to rebuild society, while "The Flash" comic series has seen multiple endings, with the most recent one being the "Flashpoint" event that altered the DC Comics universe.

The reason for the diverse endings lies in the creative freedom granted to comic book writers and artists. Unlike movies or television shows, which often have a predetermined number of episodes or a set budget, comic series can continue for as long as the creators and publishers decide. This allows for more complex and nuanced storylines, as well as the potential for unexpected twists and turns. Additionally, the medium of comic books allows for a visual storytelling that can convey emotions and themes more effectively than text alone, which can lead to powerful and memorable endings.

Data from the comic book industry shows that the average comic series runs for around 12 issues, with some running for much longer. The length of a series can impact the ending, as creators may have more time to develop the story and characters. For example, "The Sandman" by Neil Gaiman and Sam Kieth is a 75-issue comic series that explores complex themes of dreams and reality, and its ending is a fitting conclusion to the intricate narrative. In contrast, shorter series like "The Dark Knight Returns" by Frank Miller and David Mazzucchelli, which is only 4 issues long, deliver a more concise and impactful ending.

The ending of a comic series is also influenced by the audience's expectations and the publisher's goals. For instance, some series may end on a cliffhanger to encourage readers to continue following the story in a related series or to sell more issues. Other series may end on a definitive note to provide closure for the characters and the story. The success of a comic series can also affect its ending; if a series is popular, creators may be more inclined to give it a satisfying conclusion to maintain the fanbase.

In conclusion, the ending of a comic series is a multifaceted element influenced by the creators' vision, the length of the series, audience expectations, and publisher strategies. The diversity of endings reflects the rich and varied nature of the comic book medium.
