Can you mention instances in the comic book history where two arch-enemies/rivals have joined forces?

Oh, this has happened so many times, it's not even funny.\n\nAs mentioned already, Venom and Spider-Man has teamed up to beat Carnage, but also, Punisher and Spider-Man has teamed up, Spider-Man and Sandman has teamed up to take on the Sinister Six... I know Spidey has teamed up with a few other ex-enemies as well.  There's been other less notable characters that started out as criminals, but have since turned sides thanks to Spidey, such as the Prowler, Rocket Racer, Will O The Wisp to name a few.\n\nNot only that, but Magneto has teamed up with the X-men before, and so has Wolverine with Sabretooth - back in their Weapon X days, and also Juggernaut has been part of the X-men for some time now.  \n\nIn the X-Men Legends II: Rise of Apocalypse game, the X-men teamed up with the Brotherhood to fight Apoc.\n\nCaptain America had at one time, dated Diamondback, who was part of the Serpent Society.\n\nI can't think of any others right now, but will add more later, time permitting.

Grand Comic Book Database (comics.org) can be a good place to start.  Not all the title have synopses and there were some titles missing.  But the screenshots are rad.

Um out of the two mystique, but really much hotter babes in comics, have you seen the chicks in witchblade? or even more traditionaly black cat, wow, or cat woman, or posin ivy. I read way to many comics.

No. \n\nWe can see certain current issues fictionalized and addressed in some of our comics (in "Ex Machina" the hero manages to save one of the twin towers), but I think that iconic heros should not be brought into this.\n\nWhat's the point of Batman v. Bin Laden? Obviously Batman will win, but it will be a hollow victory, as the real terrorist is still at large.\n\nI'd like to see a comic about radical islam, terrorists, or even one that painted a picture of what's going on from their point of view. However, to have our mythic do-gooders clash with real evildoers could leave us feeling empty.\n\nI fully realize that Captain America was originally out smashing Nazis, but times were simpler then. The enemy had a plan, wore uniforms, and were easy to single out from non-combatants.\n\nIf Batman actually went after Bin Laden, he'd probably have to spend a fair amount of time beating up innocents for information that they didn't have. Cap can just smack any guy with a swastika armband. There's certainly a difference.

Arcs in comic book terms are stories that strecth across (or arc) more than one issue.

They both seem to make people fight a lot, and even kill each other.

wolverine. despite them being fairly evenly matched, wolverine has berserker rage on his side and when he gets like that, he can't distinguish between friend or foe and in that state, he could beat almost anyone

good question, and hard to answer!\n\nthe abomination is one of the few beings in the nmarvel universe who can make the claim of having beaten the incredible hulk. that being said, the hulk almost always prevails. i'd place my bet on the hulk.

The most recent (and best) instance in which he became evil was in Jim Lee's "Hush" storyline in the Batman comicbook last year.  Poison Ivy seduced him and he attacked Batman.  Ever resourceful, Bats was able to level the playing field with an old fashioned kryptonite punch!

I remember his name & likeness in one little comic strip. I didn't save it but I remember reading it about five years ago. That doesn't mean he wasn't featured in more comics, there are so many and I'm not really a collector.

No that's called a Rival. But that can also form a strong bond that can sometime develope into friendship.

some people say no and some say yes.  I have checked and except for ultimate marvel team-up #9 the rest count as a vaild first appearance.  To make sure though see the first time the appear in another title, you can't go wrong with that and it's good as a backup

In the beginning...  Ha.  Start in chapter one.  I am curious to know, though, what 'two' stories you are referring to.

Don't forget Darkseid- he's also one tough hombre.  Lobo has also beaten him.  Batman can also kick his butt (if he's prepared for it!)...
