Batman and Green Arrow. Two unpowered rich guys fighting crime, two very different styles, two clashing personalities.

Man, I loved that time that Batman teamed up with Nigel from Spinal Tap to solve “The Secret of the Stonehenge Strangler”. Turned out to be a midget professional wrestler who was killing people with a deadly sleeper hold while dressed as a druid.

I think that really happened…at least, as much as anything really happens…

I have to go with the Batman/ Harvey Pekar teamup.

In the comic book “real world”, I’d have to go with Batman and the Creeper. Extremes of vigilantism couple with a costume that would make The Joker blush- what more could you ask?

Batman & Plastic Man in the Joe Kelly issue of JLA, where they discover Plas has a son.

Batman and Scooby Doo – Zoinks!

I have to go with the three way team up between Batman, Plastic Man and Uncle Sam and the Freedom Fighters. It was great seeing the old “Quality” characters.

I like the first two storylines in the Superman Batman comics.

It’s so hard to pick, but I’m going to go with Batman and Etrigan, because if they hadn’t teamed up on The Brave and The Bold I wouldn’t have an Etrigan action figure.

Batman and Wildcat vs. the Joker, by Bob Haney and Jim Aparo in B&B #118 from 1975. It’s the issue where the Joker made Batman and Wildcat box each other wearing spiked cestus gloves.

I still love the old Batman/Scooby-Doo team-up, even though it’s campy as hell. Casey Kasem as Shaggy & Robin!

Batman teaming up with Kamandi seemed ludicrous to me at first, but they actually pulled it off in the cartoon series in a plausible and enjoyable fashion. LOVE seeing those Kirby characters animated!

I’d have to go with either the Batman-Scooby Doo teamup (though I’m hoping the updated “Brave and the Bold” version isn’t using the “Mystery, Incorporated” versions of the Scooby gang, but the generic direct-to-DVD versions instead… it’s not my favorite Scooby spinoff) or the “World’s Finest” Superman-Batman team (one favorite early Silver Age story: the one where Gotham City and Metropolis use both heroes to compete with each other to win the right to host some electronics convention…).

I would go with Michael Keaton and George Clooney in “Out of Sight.”

I was going to mention the Batman / Wildcat boxing one, but Cole already covered that, so I’ll say the Batman / Batman team-ups my son plays with his two Batman action figures, one a “Brave and the Bold” figure who he just calls “Batman” and the other an old “Super Powers” figure who he calls “Bruce Wayne” in order to distinguish the two.

Wow, several other people mentioned Batman and Scooby-Doo – yeah, I watched that one with my older son when he was just a little guy. Now he’s a father …! Zoinks indeed!

When I was a teenager, I thought that Velma was the best Scooby-Doo character … she kinda looked like me, only cuter.

Batman and Zatanna in Batman TAS, just a cute and fun little story that humanized Bruce a little bit.

Batman and Sugar and Spike teaming up to defeat Felix Faust. And he was even nice enough to invite them to the wedding.

The ep that always comes to mind first is the one with Batman and Black Canary teaming up against the Music Meister. But it also has Green Arrow and Aquaman.

Batman & The Creeper vs. a paper monster in a fantastic Alan Brennert/Jim Aparo issue way back in the day.

Batman with Metal Men is a treat.

I have to choose one? OK, Batman and Aquaman in the current B&B TV series, because I just love the way that Aquaman is completely oblivious to Batman’s opinion of him…

I’m going to have to go with the Batman/Superman: The Animated Movie from the Dini era where they first met. Because it was singularly great, that’s why

Bats and Commissioner Gordon. Nothing like an uneasy alliance between the caped crusader and Gotham’s finest for gritty, noir style detective stories.

I believe there was an episode of Batman:TAS in which Harley Quinn asked for Batman’s help. I may be misremembering that, simply because Harley Quinn is one of my favorite characters in Batman lore.

I also loved the Greg Rucka series “Gotham Central”. Detective Rene Montoya may never have directly teamed up with Batman, but they certainly worked on the same cases. That counts in my mind!

Batman and Judge Dredd. Watching two icons with complete opposite takes who really despise the others method but have to cooperate was a good deal of fun.

Batman and Simon Trent the Gray Ghost. One of my favorite episodes from TAS.

I’m going to go with the Batman/Plastic Man/Freedom Fighters team up on Batman: Brave and Bold. Not only did it feature my 7-year-old’s now-favorite character, Plastic Man and make her laugh at loud, but gave me a chance to explain some American history to her (making her laugh even harder that Plas was so confused), and gave us both a new version

a new, fun version of Yankee Doodle Dandy to sing together. And now she thinks Freedom Fighters (Especially Uncle Sam) are cool, too.

From way back in the seventies it was a meeting between Batman and Cain, host of the House of Mystery. Very unusual in how they never really met but Cain kept narrating and making his barbs just like he did in the mystery anthologies.

Batman and Spawn teamed up in a mystery related to the disappearance of the Colony on Roanoke Island. As a 12 year old, I couldn’t have imagined anything better than that story. Luckily, I haven’t looked at recently, I imagine it wouldn’t hold up.

Oh man so hard to answer. My favorite Batman actually is the Brave and the Bold cartoon. Favorite teamup? Dang, I’m gonna go with Plastic Man. Hilarious.

I’m too late for the contest, but I wanted to mention an old Brave & Bold story where he teamed up with Adam Strange — Adam swapped places with Batman in Gotham while Batman had to solve a murder on Rann!
