We love superheroes because their indomitable will and often noble causes inspire us. We read about and watch these people use superpowers we only ever fantasized about as children and it's all fantastic fun. This is truer than ever now on screen with their ever increasing budgets and dramatic plotlines. Of course, that's not the only reason we love watching superhero television shows. A part of the appeal is that they tend to always star incredibly attractive people. We're not just talking about the beautiful actors and actresses that portray our favorite heroes -- we're talking about the qualities that add to their undeniable sex appeal.

That's why we've brought to you 15 of the hottest heroes from both old shows and relatively new ones. To be clear, these heroes are all from current shows but their shows were popular at one point or another. In no particular order, these are the television heroes that instantly drew us in with their charisma and beauty, these are the ones that maybe even tugged at our heartstrings and kept us wanting more week after week. They may not all be main characters but, when they did appear, we got hooked.

15 CONSTANTINE

Constantine

For some fans, the appeal of John Constantine's (played by Matt Ryan) might not seem as immediate as the others on this list. Constantine is a cynical antihero who got carried away long ago, messing with the occult and damning a poor girl's soul to the depths of hell. Now he fights demons to try and save his own tormented soul from damnation.

After a few episodes of the short-lived (but fantastic) Constantine, it'll become clear as to why we've put him on our list. It's not just his impeccable style or that charming accent, it's the way he wades through the world of angels and demons with a cool, confident cynicism. He can smile and get a laugh from us, all while maintaining that air of mystery about him, just like a real hellblazer would.

14 SUPERGIRL (SMALLVILLE)

Supergirl-Smallville

The first time Supergirl appeared in a live action television series was in Smallville, in which she was played by Laura Vandervoort. Kara had been sent to Earth long ago in order to watch over her cousin, Superman. Her ship crash landed in Reeve's dam and Kara was kept in stasis, until Superman and Bizarro destroyed the dam during a battle and released the ship.

Aside from the fact that she's a total bombshell, she also drew us in with her steadfast sense of duty as well as her outspokenness, which often put her at odds with Clark. Despite that, Clark needs her, as we see when she teaches him how to fly in the episode, "Supergirl" (written by Anne Cofell Saunders) with all the patience and understanding that you'd expect from someone sent to teach and guard their cousin.

13 SUPERGIRL

Supergirl-CW

Speaking of Supergirl, what about that Supergirl from CW's show, Supergirl? She was sent to Earth to protect Kal-El, too, but her ship was thrown off course into the Phantom Zone, where she remained for more than a decade. She crash-landed on Earth and was raised by the Danvers, hiding her powers until the time was right.

Kara Danvers (played by Melissa Benoist) is selfless, kind and a little dorky, while her alter-ego is confident, powerful and a little reckless at times. Melissa Benoist does a great job at seamlessly switching between the two and exhibiting all those qualities, adding depth to Kara's character, which is something she seemed to lack in other depictions. That's why her charm alone is enough to carry the show, even when the special effects or writing fails to impress. It also helps that she's got that fantastic musculature that you'd imagine a superhero like Supergirl would have.

12 CLARK KENT

Clark-Kent-Smallville

Kal-El was rocketed to Earth as a baby and was raised by the Kents in Smallville to be a decent human being by the name of Clark Kent. Clark spent his time mastering his solar-powered kryptonian abilities as we see over the course of the series Smallville, in which he's played by Tom Welling.

What makes Clark Kent stand out from most other television show heroes? Is it his chiseled jaw worthy of the man of steel? Is it his character's unrelenting optimism in humanity? Is it his inspiring, tireless fight against powerful forces in defence of his new home? Is it all of the above, exhibited across the show's ten seasons? Yes, that last one, for sure. Few things are more attractive than human decency and the confidence to fight for the values you believe in... especially on a good-looking frame.

11 ARROW

Arrow-Poster

His name is Oliver Queen (played by Stephen Amell) and after five years stranded on a deserted island (for the most part), he has returned home to Star City in order to protect it from those who have failed it, as well as superhuman, alien and mystical forces. With his bow and arrows and his team of close friends and allies, he's become one of Star City's greatest defenders.

He's come a long way from that party boy without a care in the world and Stephen Amell has done a fantastic job at showing us that organic growth. Oliver Queen is a flawed human being, and that's what we've come to love about him. He's not just that great looking guy with abs of steel you only get from years of fighting for survival, he's also a fighter trying to redeem himself and become better for the people he loves.

10 WHITE CANARY

Sara Lance as White Canary

Sara Lance (played by Caity Lotz) has really come into her own since her appearance on Arrow. She survived her fair share of hardships on the island of Lian Yu and she too became a fierce warrior, thanks to the League of Assassins, though she left to return to Starling City and watch over her sister. After years as the Black Canary, we find her leading the Legends as the White Canary.

How could you not be completely taken by the gorgeous White Canary? She's struggled through some horrible things, as we saw in Arrow and she's come out of it stronger, better and with a bit of a bloodlust to keep things exciting. She's a leader, a phenomenal fighter and she can pull off white that white costume like no one else could.

9 THE ATOM

Ray Palmer (played by Brandon Routh) was the CEO of Palmer Technologies when he was introduced to us in Arrow. He developed a powerful suit with which he could shrink to impossibly minuscule sizes. He called himself the Atom and went on to become a superhero, first an ally of Team Arrow and then one of the Legends.

He's a charismatic billionaire with a lot of brains to go with all that brawn. For some, that's enough of a reason for him to be here. He's here because he's an admirable guy and that's pretty darn attractive. He can be reckless and arrogant at times, but he'll never deny it. He's also honorable and optimistic. This is the guy who broke up with Felicity so she could go be with Oliver. How many other guys would really do that?

8 VIXEN

vixen-legends-of-tomorrow

When the Legends travel to 1942, one of the heroes they encounter is Vixen (played by Maisie Richardson-Sellers), a member of the Justice Society of America. She aids them in order to avenge Hourman, the former leader of the Justice Society. Using a special necklace, the Anansi Totem, given to her by her mother, Amaya is able to channel the abilities of any animal.

Amaya is a no-nonsense type of lady; for her, there is the mission and only the mission. But if you think that means she's cold, think again. Beneath that shell, hardened by warfare and battle, lies a soft heart. That's what we love about her. She's brave, beautiful and like the beasts she channels, there's something wild to her. She's one of the more exciting characters in Legends of Tomorrow, so we had to include her here.

7 THE FLASH

The-Flash-Grant-Gustin

Barry Allen (played by Grant Gustin) is the fastest man alive. After a freak accident involving lightning and a shelf full of chemicals, Barry was turned into the Flash, using his powers to protect the innocent and find other metahumans. Almost too often does he find himself shifting time and creating alternate universes with new enemies, but we love him anyway.

What's attractive about Barry Allen? He's not particularly muscular like others in the Arrowverse, he's not particularly confident... in fact he's a little awkward at times. Well, that's actually part of his appeal. He's the dorky, incredibly intelligent speedster who makes us laugh with those awkward moments and clever quips. That's just as attractive to some as Oliver Queen's rock hard abs are to others, but with a better smile.

6 ORACLE

Dina-Meyer-Oracle

In the short-lived Birds of Prey series, New Gotham City had been seemingly abandoned by Batman, so the city received new guardians in the form of the Birds of Prey. One of their members was Barbara Gordon (played by Dina Meyer), also known as Oracle. Unable to physically fight crime thanks to the Joker, Oracle fights crime from her computer, using her unmatched expertise to aid the Birds of Prey.

Dina Meyer portrays the character as a confident superhero in her own right who can rock a leather outfit. Barbara is a teacher, both in her civilian life and in her nights as a mentor to the Huntress. Having been trained by Batman, you never see her in any real panic and she doesn't shy away from a fight, as we see in the episode, "Lady Shiva" (written by Adam Armus and Kay Foster) when she stood to apologize to Lady Shiva who fought her, even though Babs couldn't walk.

5 LUKE CAGE

Luke-Cage

The Netflix series follows Luke Cage (played by Mike Colter), an ex-con who was wrongfully imprisoned and experimented on, resulting in superhuman strength and a virtually indestructible anatomy. However, he doesn't go looking for chances to use these powers. For the most part, he's just trying to live a simple life as an average person, though the streets of Harlem often push him in a different direction.

A big, brawny ex-con who can walk through the streets of Harlem and fight the good fight with that much confidence is an obvious choice for this list. He towers over everyone else and doesn't need a colorful or fancy outfit to stand out and dominate the screen. He just does it, despite his efforts to keep a low profile. Is it any wonder he's gotten into bed with Misty Knight, Jessica Jones and Claire Temple?

4 QUAKE

Quake Agents of SHIELD

Agents of S.H.I.E.L.D. introduced us to Skye (played by Chloe Bennet) in its pilot episode, in which we see her as a member of the hacktivist group, Rising Tide. She was invited to join S.H.I.E.L.D. and during one of her missions, was exposed to the Terrigen Mists, unlocking in her the ability to generate shockwaves.

It wasn't just because she's a stunning girl in uniform, though does look great in that uniform. We've seen her develop a lot over the course of the show. She went from being the hacker, Skye, to Daisy Johnson, the Inhuman vigilante and ally of S.H.I.E.L.D. Through it all, she has proven to be fiercely loyal to her friends and unyielding in her fight for true justice, as we see when she declared that she would team up with the Spirit of Vengeance instead of the secret organizations she was used to.

3 DAREDEVIL

Matt-Murdock-Netflix

After a truckload of hazardous material blinded him, the life of Matt Murdock (played by Charlie Cox) changed forever. He studied hard and trained harder to become a better man. He's a suited blind attorney by day and the red-armored devil of Hell's Kitchen by night, taking on criminals who are otherwise untouchable, like the Kingpin.

Charlie Cox's performance as Matt Murdock has to be praised, not just for the fact that he portrays blindness so well, but for his ability to bring something very human to the character. He knows that he's doing the right thing but he doubts himself at times and still has trouble making the right choices... you also have to praise those muscles for screaming, "I fight crime in my free time." Hell's Kitchen is hot indeed!

2 HAWKGIRL

dc-hawkgirl

In the Arrowverse, Kendra Saunders (played by Ciara Renée) is just a regular girl who Cisco dates; that is, until Carter Hall -- Hawkman -- arrives and tells Kendra of who she really is: the reincarnation of the ancient Egyptian priestess named Chay-Ara. She discovers herself and sprouts wings, earning the nickname Hawkgirl... as you do.

She's the cute barista in the beginning, one of the few normal people we see in the Arrowverse. She's still that person, only now she's trying to wrap her head around everything that's happening, including the powerful hero she truly is. Unlike many of the other superheroes in that universe, most of whom were highly trained and pretty superhuman to begin with, we can relate to Kendra in a lot of ways, which adds to her allure.

1 AGENT CARTER

Agent-Carter

Okay, Agent Peggy Carter (played by Hayley Atwell) isn't technically a superhero. You have to admit, though, that she's earned that title as a soldier, a founding member of S.H.I.E.L.D and as a top notch, confident agent despite the misogynistic attitudes that were common at the time.

At a glance, Carter is the embodiment of beauty in the 1940s. Go deeper and you're bound to be even more captivated by her dedication to the protection of liberty and her drive to prove wrong everyone who doubted her ability and skill based on the fact that she's a woman. She remains confident in herself and undeterred. As you've probably seen for yourself going through this list: few things are more attractive than confidence. It's also difficult to resist anyone who looks and sounds like Hayley Atwell.
