Jim Henson once allowed me to visit the Muppets on set and spent an entire day showing me how he and the other puppeteers performed Kermit and all the characters! After that, I was lucky enough to work with both George Lucas and Steven Spielberg on many fun animation projects and learned so much from them.

I felt that, with 'Zatanna,' I had a chance to do a story about a strong, driven woman.

I remembered what it was like: the weirdness, being the odd man out, trying to make my way around campus, and trying to figure out who my friends would be, who to steer clear of. I wrote it all down in a fanciful way - the feelings of alienation, the feelings of uncertainty, of being away from home for the first time.

There's a sort of eternal, indefinable 20th century quality to 'BTAS.' We never really pegged the decade, but it's anytime in the 20th century, so I often harkened back to things from the '40s or '50s.

It's wrong to become a bully yourself or to take it out on other people, and in my case, I just retreated to a place where I was safe. And that place was my imagination, books, and television.

I really didn't have any plan for her other than the henchgirl role, who was better at getting laughs out of the other gang members than the Joker was. I gave her the name Harley Quinn because I thought Harley was a fun name for a girl, and a lot of 'Batman' character names have a bit of a pun to them, like E Nygma.

Most female characters have either been the temptress - like a Betty Boop type - or the victim - like an Olive Oil type.

The Joker is a tremendous vehicle for talented actors. Cesar Romero's was a bubbly, lunatic criminal. Nicholson did him as a vain, preening manipulator. Heath's performance of the Joker was remarkable, too. His was a low-simmering crazy street clown. Joker can be played all these ways, and they're all true.

With 'Tower Prep,' Cartoon Network wanted to go into a new area where no other kids' programming was going. There were a lot of kids' sitcoms on the air, but they wanted to really go with more of like an adventure/drama feel.

There are some short stories in R. Crumb comics that are just wonderful and touch me in ways no other comics do.

As much fun as it is gaming, I have so much to do that I've had to get away from them. I still enjoy them. When I go to a friend's house and they have a game on, I'll happily join in and play.

Encourage your kids to be creative. When you see them tracing a character from TV or a comic, say something like, 'That's nice. Now how about you create a character yourself?' Keep kids curious and excited about creating.

When you're writing for a game - even if you're using very well known characters like Batman and his villains who lend themselves to many different interpretations - you have to keep in mind that you're writing for a different medium. Things are a bit more straightforward than it is for a feature film or a TV show.

In those times when a kid first tries to express themselves creatively, it sets them on a different path. Sometimes, that path can be really wonderful and can lead to a career doing some of the things you love. I also think that the price on that is a certain amount of alienation or distance created between a lot of the people around you.

Wonder Woman is out there very much defending the right and being strong and being a positive role model.

To overcome any form of adversity, to not give up, to not give up on yourself, your dreams, to not sequester yourself away from people - that's the most important thing to do with your life.

There's a different energy to Spider-Man than there is to Batman.

Jeph Loeb has been great to work with, and he's been really supportive of some really bizarre ideas I've had.

When it's only you that you can rely on, you're surprised at the resilience you have.

You don't have a Batman without Bruce Wayne. Batman is the edge or scary image for Bruce to use.

As much as I liked the build-up to Christmas, the week after always socked me with the blues.

I get it, cops deal with a lot, but at the same time, we crave justice, and we do want to believe things are going to be all right.

If 'Jingle Belle' harkens back to anything, it's sort of the Harvey Comics. Not really 'Archie,' but more of a teenage version of what Harvey Comics would have become, with the type of fantasy wonderland of her and her various friends.

A lot of times, female characters - particularly the villains - come off as very one-dimensional. They get the short shrift in that they're only given the snappy comeback, or they're relegated to a very stereotypical role. I want to know what's driving them - that's what's really interesting.

'Batman Beyond' started because we were tossed a curve, because the higher ups at Warner Bros. wanted a different take on him.

I wouldn't call the Joker exactly easy to write.

Bruce Wayne needs a sense of humor to do his job. Batman, for a very long time, was going to a very dark place.

If everybody's a winner, nobody has to try very hard.

My story is just my story, and it's not nearly as traumatic as some.

'Jingle Belle' spins out of my love for just sitting down and reading a good, fun Sunday morning comic strip panel.

Hugo Strange is interesting in the sense that he's a master manipulator. He doesn't really engage Batman in any sort of physical way. His weapon is his mind, and he's very incisive and clever: he reads people and sizes them up almost instantly.

Batman is dark and moody and spooky and, in some cases, methodical.

You can have villains like the Penguin, who strut around in a tuxedo with an umbrella, and Poison Ivy and all of the fantastic stuff she does, but unless there's a bit of a human in there, and unless there's a credible threat, then Batman himself doesn't work.

With 'Wonder Woman,' I did one story with Alex Ross, and I had a lot of fun doing it, but I don't think I could do a 'Wonder Woman' book on a regular basis, because there's so much history there and so much mythology and everything.

Kids love the Hulk, but they're not really sure: 'Is he a monster or is he a hero?'

I was working in cartoons. I could go to Comic-Con, buy the Hal Jordan ring, I could buy animation cels, but at the end of the day, I come back to an empty apartment. I had a life that was only around me, and when I was broken, my world was broken.

In every story I've written with Batman, there's an element of justice - you never want to have the story end on a defeatist or a cynical note.

When you do an animated series and add characters who are not from the canon, you really have to win over the hardcore fans.

I grew up loving cartoons, comics, magic, and writing.

To some degree, I don't think 'Batman' works in a completely modern city; I think Gotham has be reflective of his personality and those of his enemies.

That's the thing about writing for a lot of the villains is that, as a writer, you kind of have to put the best part of your own personality aside and instead focus on whatever little strange quirks you may have in your personality.

You have to remember, when someone hurts you, that you are so much more than what they took from you.

You have to be kind to yourself to survive in the world.

Initially, kids are attracted to Superman as a hero because he can take care of problems and still appear as friendly as your dad.

You don't have to limit yourself or feel that you've been limited by an act of cruelty.

Mickey Mouse did not stay the little squeaky guy in 'Steamboat Willie.' He went on to have many different versions.

We're all painfully aware of how suddenly violence can occur, how crippling it is, and how survivors have to find a way back from that.

As much as I love elements of Spider-Man's past, I don't really want to go back in and retell the Gwen Stacy and Green Goblin story in animation just so I can do my take on it. I don't want to redo the first 'Spider Slayer' story.

I look at the Marvel movies and the DC movies and various creators' creations, and I think, you know, that's really pretty cool.

I'm a very visual thinker, so the characters are running through my head, doing what they're doing when I'm writing them. And there'll be moments where I'll just kind of throw a look off to the side as if I'm talking to one of the characters. It's always been something that I've had with me since I was a little kid.
