Here is an archive of all the past top five lists I've one over the years.

With the news that Mary Jane Watson will soon be a supporting cast member in the pages of Invincible Iron Man, I thought it would be interesting to spotlight other notable examples of supporting cast members who moved from one title to another...

NOTE: We're not talking about characters who had their own titles and then ended up as supporting characters in another character's book, like Jessica Drew in Wolverine. We're just talking characters who were supporting characters in one book and then became supporting characters in another book.

HONORABLE MENTIONS

Father Craemer

Father Craemer was the prison chaplain in Suicide Squad.



After Suicide Squad ended, John Ostrander brought Craemer with him to The Spectre...





Thanks to Jacob Levy for suggesting the good father.

Liz Allan Osborn

The interesting thing about Liz Allan is that while she was originally one of the girls that Peter Parker vied for in his personal life, or in the case of Liz, she vied for Peter, as seen in this bit from Amazing Spider-Man #24...



When he graduated high school, the character was just flat out dropped. I mean, don't get me wrong, both Mary Jane Watson and Gwen Stacy were more interesting than her, but you'd think she'd still pop into a story here and there. Instead, it was over a hundred issues until we saw her again in Amazing Spider-Man #132, when Gerry Conway presumably wanted to beef up Peter's circle of friends (which had recently taken a famous hit due to the death of Gwen)...



In Amazing Spider-Man #166, Harry Osborn and Liz get engaged.



She and Harry remained supporting cast members for the next decade or so, along with their kid, Normie Osborn. Eventually, though, Harry went nuts and died.

When he began his run on Daredevil, writer Karl Kesel brought Liz Osborn over to Daredevil as Foggy's new love interest...



She remained in the book until Kevin Smith restarted the series, at which point he wrote Liz out of the books. Norman Osborn has recently returned to the pages of Spider-Man, and he naturally was interested in his grandson, so Liz became a Spider-Man cast member once again. More recently, she has been a major supporting cast member (and possible love interest for Miguel O'Hara) in Spider-Man 2099.

5. Marlo Chandler

The punderful Marlo Chandler was first introduced along with the introduction of the Hulk's "Joe Fixit" persona, from his time when he worked as an enforcer in Las Vegas. Marlo was his girlfriend...



Even when the Hulk personalities merged, Marlo stuck around, only now she dated fellow supporting cast member, Rick Jones. They eventually got married...



Over time, they separated.

Writer Peter David, who had created Marlo, eventually brought her over to his newly launched Captain Marvel comic book, as Rick had now merged with Genis-Vell to become the new Captain Marvel...





While in the book, Marlo had a brief relationship with another supporting cast member in the book, Moondragon...



4. Karen Page

Karen Page was the secretary for Matt Murdock and Foggy Nelson, as well as the main love interest for Matt Murdock as the Daredevil series began in 1964.



In Daredevil #57, she even learned his secret identity!





Eventually they broke up and Karen set off to Hollywood to become an actress. It was here that she became a supporting cast member in the pages of Ghost Rider #13, as Johnny Blaze got a job as a stunt rider on the Stuntmaster TV series that Karen was the female lead on...





What's amazing about their relationship is that the writer who brought her into the book, Tony Isabella, was taken off the title six issue into her stint as a cast member. There were a few different writers after him, and yet each one of them had a chance to take her out of the book but they each just doubled down on her presence in the title...



But then in Ghost Rider #26, Johnny just abruptly leaves town. And that was it for Karen Page (outside of a cameo in an issue of Marvel Two-in-One set in Hollywood) until Frank Miller brought her back to Daredevil in Born Again.

Go to the next page for the top three!

3. Maggie Sawyer

Maggie Sawyer was a great addition to the Superman titles during John Byrne's reboot, and it was interesting to see a lesbian character given such prominence in the 1980s...





She even got her own mini-series during the 1990s!



After a while, though, for whatever reason she became less and less of a presence in the Superman titles, so Greg Rucka asked and was given permission to bring her over to Detective Comics, where she replaced Harvey Bullock in the GCPD in Detective Comics #764...





She eventually became a major part of the Gotham landscape, particularly as the new love interest for Batwoman. They even eventually got engaged....



2. Snapper Carr

Jacob Levy reminded me that Snapper belongs on the list.

He debuted as the Justice League's mascot...



After being tricked into betraying the League, he gave up his affiliation to the League and went into limbo for years until he popped up as a supporting cast member, in of all places, Supergirl's feature in Superman Family...



He gained superpowers during Invasion! and became a member of the shortlived superhero team, the Blasters...



He then became a supporting cast member for Hourman...



and then Young Justice, where he served as their adult supervisor...



1. Rick Jones

Rick Jones is the king of this category.

Okay, so he is introduced in Incredible Hulk #1, as the reason Doctor Bruce Banner was caught in a gamma bomb explosion...



Feeling responsible, he sticks around to help the Hulk out...



Well, he inadvertently helps to form the Avengers in an attempt to capture the Hulk. After the Hulk joins the Avengers, Rick keeps hanging around. This leads to a chance meeting with Captain America, who thinks Rick is his old partner, Bucky...



Cap decides, "Well, if he LOOKS like Bucky, I might as well train him to go fight deadly villains, right?" So he eventually becomes Cap's new partner...



Then, however, he ends up finding some nega bands and develops a relationship where he switches bodies with the Kree hero, Captain Marvel, in a clever twist on the original Captain Marvel from Fawcett Comics (with Rick in the Billy Batson role)....



After Captain Marvel's story ended, Rick was sort of aimless and ended up a supporting character in Rom, of all places...



Then Rick came back to the Incredible Hulk for a long spell, before merging with the NEW Captain Marvel (as I showed you above in Marlo Chandler's entry on the list). He eventually became the new Abomination in the pages of Hulk, but he hasn't appeared as a regular character in any book since his stint with Captain Marvel.
