11 Iconic Comic Book Characters Originating from TV Shows

by

While many think comic books came first, television actually created some of the most famous superheroes. Over the years, TV shows have launched original characters from Marvel and DC that became incredibly popular and were later included in the official comic book storylines. These characters often went on to appear in movies, video games, and other media.

Many characters who first appeared on TV have become incredibly important to their respective franchises. Starting with villains created for Batman animated series and expanding to original characters from the Arrowverse who even made it into the DC Comics universe, these TV creations have significantly impacted their worlds. Some are now widely recognized, while others are beloved by dedicated fans.

Harley Quinn In Batman: The Animated Series (1992)

Harley Quinn first appeared in the animated series Batman: The Animated Series, in an episode called “Joker’s Favor.” She quickly became incredibly popular with DC fans. Originally, creators Paul Dini and Bruce Timm planned her as a one-time sidekick for the Joker, but her sad past and quirky personality instantly connected with viewers.

Harley Quinn first appeared in DC Comics as part of the ongoing story from the popular animated series in The Batman Adventures #12, which was released in 1993. Six years later, in 1999, she was officially established as a core character in the DC Universe with the release of Batman: Harley Quinn.

Harley Quinn has quickly become one of DC’s most popular antiheroes. She’s led her own comic book series, appeared in video games like Injustice, and starred in movies like Suicide Squad, where she was a perfect fit for the role. Her journey from a character first seen on television to a DC Comics icon is truly remarkable.

X-23 In X-Men: Evolution (2000)

X-23 debuted in season 3, episode 10 of X-Men: Evolution as a new take on the story of Wolverine. Created for the animated show, Laura Kinney is a clone built to have Logan’s powers. She was first intended to appeal to viewers who enjoyed a younger Wolverine character.

As a big X-Men fan, I always appreciated that Wolverine didn’t get the teen makeover in X-Men: Evolution like some of the others. But you know what? X-23 totally nailed that vibe, and she became so popular that Marvel actually brought her into the main comic book universe with NYX #3 back in 2004. It was a really cool move!

Initially created as a spin-off of Wolverine, X-23 quickly developed into a unique and fully developed hero. She eventually even took over the Wolverine identity in the comics and appeared in the films Logan (2017) and Deadpool & Wolverine. This success has established her as one of Marvel’s most impactful characters to originate in television.

The Wonder Twins In The All-New Super Friends Hour (1977)

The Wonder Twins first appeared in the seventh episode of the animated series The All-New Super Friends from Hanna-Barbera. The show already included popular DC heroes like Batman, Superman, Wonder Woman, and Aquaman. Zan and Jayna, known as the Wonder Twins, were designed to attract younger viewers and bring a science fiction element to the Super Friends team.

The Wonder Twins were once the subject of ridicule for their simple abilities, but they eventually became a beloved, niche favorite among fans. They first appeared in a DC comic book, Super Friends #7 in 1977, which was connected to the animated series. Later, in 1995, they were officially added to the main DC Comics universe in Extreme Justice #9.

The Wonder Twins gradually became more complex and well-developed characters. They moved beyond their original cartoon appearances, showing up in DC Comics, animated movies and TV shows. Their inclusion in the popular live-action series Smallville really solidified their place as official parts of the DC Universe.

Firestar In Spider-Man And His Amazing Friends (1981)

Firestar, a Marvel character, first appeared in the animated series Spider-Man and His Amazing Friends. She was created because the show’s producers wanted to feature the Human Torch, but couldn’t due to rights problems. As a solution, they designed Firestar with a backstory as a former member of the X-Men.

Firestar first joined forces with Spider-Man and Iceman as a teammate with fire-based powers. Fans loved her so much that Marvel officially added her to the X-Men comic book series in 1985, starting with issue #193. She then starred in her own short comic series, which finally revealed her complete backstory within the established Marvel Universe.

Firestar eventually became a member of both the New Warriors and the Avengers. She was a key player in significant Marvel events, most famously “Civil War.” Over time, through appearances in animated series, comics, and video games, she evolved from being a character created to connect different TV shows into a well-established and enduring Marvel hero.

Terry McGinnis In Batman Beyond (1999)

Terry McGinnis first appeared in Batman Beyond as the new Batman, taking over from Bruce Wayne in a future setting. He was created to appeal to younger audiences and brought a fresh, more emotionally open and sometimes impulsive style to the role. Terry has since become an official part of the Batman story through the Batman Beyond comic books.

Terry McGinnis’s version of Batman became officially part of the main Batman storyline during the “Countdown to Final Crisis” event in 2005. He was then featured in regular Batman comics published by DC Comics.

I’ve always been a huge Terry McGinnis fan, and it was amazing to see how popular he became! It was so cool when they brought him back into DC’s animated world – he showed up in movies, TV shows, and even video games. And honestly, the love for him hasn’t died down at all. People, including me, are still hoping to see a live-action version of his story one day!

Condiment King In Batman: The Animated Series (1992)

I still remember when Condiment King first showed up in Batman: The Animated Series! He was totally a joke villain, made just to be funny, but honestly, he was brilliant. The show’s writers were so clever and knew exactly what they were doing, and fans instantly loved him. It was awesome to see him become an official part of DC Comics canon when he appeared in Birds of Prey #37 back in 2002!

Condiment King has become a recurring character in several animated shows, usually played for laughs as originally intended. His rivalry with Kite-Man in Harley Quinn is particularly funny, and he’s also had some memorable roles in the Lego Batman films.

Condiment King, originally a comedic character, has surprisingly stuck around in comics and other DC projects, proving that even characters meant as jokes can become enduring. His evolution from a silly animated bit on Batman: The Animated Series to a recognized comic book villain demonstrates the show’s significant and lasting impact on DC Universe history.

John Diggle In Arrow (2012)

John Diggle joined the show Arrow as a key ally to Oliver Queen. Initially hired as a bodyguard and military veteran, their bond grew into a close friendship. Diggle became Oliver’s most trusted friend and someone he could always confide in during his work as a vigilante. As a character created for the Arrow universe, Diggle quickly won over fans with his strong moral values and relatable emotional struggles.

As a huge comic and TV fan, I always thought Diggle was a fantastic addition to the DC universe. It’s cool how he officially showed up in the comics with Green Arrow #23.1 back in 2013. But what really struck me was how he became so tied to the Green Lantern stories, both on the small screen and in the comics themselves. Diggle’s journey proves that a great TV character can actually influence and even change the direction of a comic book world – it’s a testament to how impactful live-action shows can be!

Egghead In Batman (1966)

Egghead first appeared in the 1960s live-action Batman television show. Vincent Price famously played the character, a colorful villain known for his obsession with eggs and puns. Although he wasn’t originally in the Batman comics, Egghead became popular enough to eventually be included in the official DC Universe.

Egghead first showed up in DC Comics as an unnamed patient at Arkham Asylum in Batman: Shadow of the Bat issues #3-4. He was later officially named in Batman: The Brave and the Bold #16. Since then, he’s appeared in animated shows and other adaptations, keeping the fun, lighthearted style of the 1960s Batman series alive within the main Batman storyline.

Mercy Graves In Superman: The Animated Series (1996)

Mercy Graves first appeared in Superman: The Animated Series as Lex Luthor’s assistant and protector. She quickly became a memorable character, appearing in other animated shows as well. DC Comics officially added her to their main story continuity in Detective Comics #735, published in August 1999, as part of the “No Man’s Land” storyline.

Mercy has become a popular character, appearing in many comics, animated movies, and video games. She’s even been brought to life in live-action films like Batman v Superman: Dawn of Justice, and has also appeared in several live-action superhero TV shows.

I’ve always been fascinated by Mercy! Seeing her pop up in shows like Smallville, Supergirl, and Titans was fantastic. Even with a few changes to her look over the years, she consistently makes Lex Luthor’s schemes so much more interesting. Honestly, I think her appearances really prove that they can successfully update and revitalize Superman’s world and the characters around him through animation.

Livewire In Superman: The Animated Series (1996)

Livewire, a villain with electric-based powers, first showed up in the animated series Superman: The Animated Series. She started as Leslie Willis, a popular radio personality, and got her powers after an accident that involved Superman. Because she became so popular with fans, she later appeared in the comic book Superman Adventures #5 (1997), which was directly connected to the animated series.

Livewire officially became part of the established Superman story in 2006 with her appearance in Action Comics #835. Since then, she’s become a frequent villain in the Superman universe, appearing in comics, animated shows, and video games.

Livewire came to life in live-action adaptations of Superman, appearing in both Smallville and Supergirl within the Arrowverse. Her journey from a cartoon villain to a character featured across different media demonstrates how strong television characters can significantly expand and enhance comic book lore. She’s now considered one of the most iconic original characters created during Superman’s animated years.
