This week Marvel unveiled the cover of <b>All-New, All-Different Avengers #4</b>, which features a tease at a superhero romance would be <i>surprising</i> to say the least – Captain America and Thor. <p> While it's too early to say if the cover is an old school comic book tease or a preview of things to come, if the Goddess of Thunder and the Sentinel of Liberty do 'couple' figuratively or literally, it would be one of the more unpredictable pairings in comic book history. Imagine if just a couple of years ago someone had told you Thor and Captain America would be hooking up... Well, we'll leave it at that. <p> Superhero hook-ups are a dicey topic. When it comes to most superheroes, the genre is decidedly PG-13. But sometimes things get… Steamy. While we’re not sure how far Cap and Thor’s romance will go, this list explores ten times superheroes threw down – in the sack. Just like in real life, some of these couplings have stood the test of time, and others resulted in little more than a super-powered walk of shame, but either way, check out the countdown for some of the biggest ones. Parental advisory suggested. <p>Oh, and for you romantic types, we <a href=>have a countdown for you about all this, too</a>.


Oh Roy Harper, why do you wind up on all of our lists? <p>When Roy decided to go "legit" as a hero back in the old DCU, he joined up with Checkmate, the international espionage agency of the DC Universe. One of his assignments had him going undercover to tail Cheshire, a supervillain, and find out about her organization from the inside. <p>Well, he certainly got inside. After hitting and quitting, he took off, leaving the pregnant Cheshire behind. She would later have the child, Lian, and eventually freely give her over to Roy. <p>Unfortunately, that didn't work out too well either, as she wound up dying under his charge. Fortunately, the relaunch seems to have just erased all of that altogether! (Not that Roy hasn't gotten involved in some eyebrow-raising entanglements in the "New 52.")


This one may really be more of a "Eh, shouldn't they have all along?" When you take the ultimate specimen of a man and ultimate specimen of a woman, it only makes sense for them to come together. <p>In the "possible future" Elseworlds story <b>Kingdom Come</b>, the story ends with a kiss between Kal-El and Diana, hovering above the ground. Then the epilogue hits, which reveals the two of them have uh, "flown the invisible jet" together, and that Diana is pregnant. <p>But a Superman/Wonder Woman romance is no longer limited to the territory of "imaginary stories" (other than the fact that they're both fictional characters): Supes and Diana are now a couple in continuity, with a romance sparked early in the "New 52" in <i>Justice League</i>, and has been going for some time, remaining the status quo for the time being (Clark Kent and Lois Lane are, for now, "just friends"). In fact, the pair have their own ongoing series, meant to explore what it means for the two most powerful beings on the planet to be an item -- and to be a past item.


Norman Osborn famously murdered Spider-Man's girlfriend Gwen Stacy in the classic <i>Amazing Spider-Man #121</i>. But as revealed in the 2004 storyline "Sins Past," their shared history is actually a bit more complicated than just that. <P>Turns out, Gwen Stacy and Norman Osborn who, let us remind you, is the insane, murderous Green Goblin actually had a consensual congress, as creepy as that may sound. This dalliance also resulted in Gwen being pregnant with twins, who aged prematurely and showed up to attack Spider-Man. In Peter Parker's quest to confirm that these twins were indeed the offspring of his lost love and greatest enemy, he dug up Gwen's grave to fetch a DNA sample. The "ol' Parker luck," indeed.


This one is notable not for being shocking or creepy, but for how delightfully normal it is. Here are two characters, each with their own crazy pasts and villainous ways. They are fleshed-out and unique, and they also happen to have a sexual relationship. The only shock is that while it was shown in some level of detail, it was never pushed out as <i>being</i> shocking. <p>Writer Gail Simone has been a strong proponent of having other-than-heterosexual relationships in comics. It's fitting that she wrote one of the best examples. The couple had their troubles for a while, but wound up in a very happy and committed relationship. Um, until Knockout died (don’t worry – she got better). The pair have not been seen together in the New 52 just yet, but Scandal recently returned in the relaunched <b>Secret Six</b> series.


Chuck Austen's early-to-mid 2000s X-Men run was marked by controversy – Angel dated Cannonball's little sister (while his little brother, who also happened to have angel wings, had his own fatal relationship), Nightcrawler was revealed to essentially be the son of Satan and a nurse fell madly in love with comatose Havok. <p>But one of the moments that angered fans the most was the Juggernaut and She-Hulk had a meeting between the sheets that appeared to be both unstoppable and savage. Not only did She-Hulk show questionable moral judgment in getting involved with a villain (who, to be fair, was in the midst of an attempted reformation at the time), she was also representing Juggernaut as an attorney at that point. Despite what prime time TV might suggest, a lawyer having sex with his or her client is generally not part of "attorney-client privilege," and is in fact, frowned upon. <p>At least one prominent creator wasn't a fan of the hookup: Dan Slott wrote it out of continuity during his <I>She-Hulk</i> run.


While Newsarama has a certain level of editorial leeway to discuss more adult-oriented topics (allowing us to publish this countdown in the first place) discussing the infamous first hook-up between Jessica Jones and Luke Cage in Brian Bendis' 2001 then mature-readers MAX series <i>Alias</i> is proving a little difficult. <p>How do we back into this topic without upending our general audience's mandate, and becoming the butt of jokes? <p>Ah forget it, guess it can't be done, only to say we think it's a fair bet that Jessica and Luke's daughter Danielle wasn't conceived that evening. <p>Oddly enough, there’s a scene in the first episode of Netflix’s <b>Jessica Jones</b> series that somewhat emulates this bit from the comic book. Check out our review of the episode <a href="">right here</a>.


Cyclops is never alone for long. After his long-time girlfriend, Jean Grey, was presumed dead post-"Dark Phoenix Saga," his grief took the form of marrying Madelyne Pryor, a clone of Jean. <p>Then in Grant Morrison's <i>New X-Men</i>, when things got rocky in his marriage with the real Jean Grey, Scott turned to Emma for support... which soon turned into a full-fledged telepathic affair. <p>Then when Jean died at the end of Morrison's run – for good this time, it seems, though her younger self came to the present day, where she currently remains – Emma and Scott wasted no time in taking their psychic tryst to the physical realm, literally kissing while standing on Jean's grave. But it's not as bad as it sounds; from beyond the grave, Jean Grey was telepathically urging Scott to move on. (Hey, that's the X-Men for you.) <p>Scott and Emma haven’t been an item since <i>Avengers Vs. X-Men</i>, and it seems that, in the "All-New All-Different Marvel" universe, Cyclops isn’t exactly around. However, his younger self – and the younger Jean Grey – remain in the present day.


Ummmm... <i>damn</i>. <p>Was there any scene from the first month of The New 52 in September 2011 that got fans talking more than the final sequence of the Judd Winick-written <b>Catwoman #1</b>? <p>Sure, the relationship has already been hinted at, both in interviews and <i>Detective Comics #1</i> earlier that month, but in an issue filled with sex and skin (see the cover and pages 1, 8, and 11), it's the last 4 pages that take it – and the long-time flirtation between the Cat and the Bat – to a whole new level. <p>Expect a lot of debate about whether arguably the most disciplined character in comic books would give in to the moment like that, some questions about the “Still... it doesn't take long...” line (really Bruce?), and a few new jokes about the contents of Batman's utility belt. <p>Of course, it's gone farther over in the pages of <b>Earth 2</b>, where Selina and Bruce were married and had a child, Helena, who now fights crime as The Huntress.


When it comes to "no... just no..." there probably hasn't been another moment in comics that pops to mind more than this one. In Mark Millar's initial run on <b>Ultimates</b>, it was implied but never outright said or shown that this brother and sister, the children of Magneto, were... living in royal tradition. <p>Then Jeph Loeb came along and decided it was time to be up front about the situation, having Ultimate Wasp explain it all to Ultimate Captain America. <p>Wasp: "You don't get it, Mister Rogers, Do you? They love each other." Cap: "Of course, they do. They're brother and sister." Wasp: "No, it's more than that. They're <b>in</b> love." <p>Yup, ew. <p>The pair appeared in <i>Avengers: Age of Ultron</i>, and while they were certainly close, there was no hint of any Lannister-like twin shenanigans in the film.


If there's an unwritten rule about sex and superheroes, it's that the unsettling extracurricular implications of the superpowers of folks like the Atom, Colossal Boy, and Mr. Fantastic are mostly left (thankfully) unsaid, beyond dialogue in Kevin Smith movies. <p>But then in 2003, Geoff Johns broke that rule with extreme prejudice with this, um, "memorable" scene featuring super-shrinker/grower Henry Pym showing some southern hospitality to ex-wife Janet Van Dyne during the writer's short-lived <b>Avengers</b> run. <p>There really isn't much left to say about this one - it does its own justice - other than to say if you haven't already seen it and are too curious not to, <a href=>take a look at the full-size version</a>. <p>Consider yourself forewarned...
